1. Introduction

Google Voice is a free service offered by Google and is designed to help you manage yourphone calls. When used for its original intended purpose, Google Voice can add unlimitedcalling to and from US phone numbers to any landline. With a little more effort, that benefitcan be extended to cellphones with "calling circles", or plans that allow a certain number ofnon-free phone numbers to be converted into free calls. With even more effort and asuitable phone, the feature can be further extended to not only maintain free calling evenafter a carrier decides those calls should no longer be free, but to also maintain free calling

while roaming outside of the United States. Finally, with the greatest amount of effort, oneor two lines with unlimited calling 24x7 can be added to any home or business.

2. Free Calling from a Landline

Google Voice offers two ways to enable 24x7 free inbound and outbound calling for landlinephones based in the US. First is a method that works the same way no matter what kind ofphone you end up using to make a call. From the main Google Voice web page(http://voice.google.com) you are able to enter phone numbers or choose contacts fromyour Google Voice contact list. With the phone number entered or selected, click the Call

button or link.

When viewed on a full PC browser, you will be asked which phone you would like GoogleVoice to ring. When viewed on a mobile phone browser, Google Voice will dial the phonenumber currently selected in the "My Mobile Number:" line on the Settings page. No matterwhich version of the website you use, ensure that your landline is selected as the phone youwant to use for the call. Start the call and the selected phone will start ringing. As you don'tget the option to choose which phone to ring when using the mobile browser, you mustensure you have the correct phone line selected prior to initiating the call.

Once Google Voice calls you, answer the phone. You will immediately hear the ringing soundof an outbound call. This is Google Voice connecting you for free to the number you enteredor selected on the website. As landlines don't typically incur any charges to receive calls(except "collect calls" where the recipient is asked to pay), there are no special steps totake to receive calls for free. If you are home quite frequently, don't have unlimited long

distance calling on your house line, have access to the web on your cellphone, but don'thave a lot of cellular minutes to spare, this is a great way to make unlimited free longdistance calls from your home, without giving out your home phone number.

Just pull out you cellphone, bring up the Google Voice page, make sure your house phone isselected as your Mobile phone number, and enter or select from the directory the phonenumber you would like to call. This method works regardless of whether or not your GoogleVoice number is a local call to your house number since all calls will be inbound to yourlandline.

The second method is entirely different, and is most beneficial if the Google Voice numberyou selected at signup is a local to you and you don't have long distance service. It is alsomuch simpler to use. Just pick up your phone and dial the Google Voice number you

selected. From the main menu, press the number 2 and you will be asked to dial thenumber you wish to reach. Google Voice then connects you, for free, to the number youdialed, so long as the number is in the US.

If your landline already has unlimited long distance or the numbers you call are within yourlocal or regional flat rate calling area, the main benefit of using Google Voice is to maskyour home phone. The people and businesses you call will see your Google Voice number ontheir caller id, and will only need to know one phone number to reach you.

3. Free Calling from a Cellphone (using the Voice plan)

Central to Google Voice is the ability to manage your phone calls and SMS text messages.Just as when using your landline, Google Voice can also help you mask your personalcellphone number to other parties,showing them just one phone number for reaching you.With a little planning (and a little cooperation from cellphone companies), Google Voice canhelp you turn your cellphone into a flat-rate, unlimited use phone line. There are generallytwo ways this can be achieved.

Cellphone usage is priced differently in the US from almost every other country. In general,US cellphone users are charged minutes for both incoming and outgoing calls. The same istrue for text messages, although unlimited text messaging plans have been available acrossall of the major carriers for many years. To help retain and build their customer bases overthe years, cellphone companies began by offering unlimited calling to other cellphonesoperating on the same network. Even that wasn't even enough eventually, and companiesbegan allowing customers to select a handful of out-of-network phone numbers anddesignate them as effectively being "in network". The out-of-network numbers don't have tobe other cellphones or landlines -- users can generally pick any set of numbers they like,and they will never be charged for the minutes used during calls to or from the numbers onthe list.

As described above, there are two ways in which calls involving the Google Voice Numberselected by a Google Voice user can be used to branch out to free calls to any other phone


3/31

number in the US free of charge. First, the user can access the Google Voice website andenter or select a number they want to call. Google Voice will then call the user at the phonenumber where the user indicated they can be reached, showing a caller id of the user's ownGoogle Voice number. When the user answers the incoming call they will be connected tothe phone number entered or selected at the Google Voice website, free of charge.

Alternatively, if the user does not want to use the Google Voice website or does not have asmartphone capable of browsing the web, the user may still dial their own Google Voicenumber. Google Voice will recognize the call as coming from a phone that is managed bythe user, and will offer to play any waiting voicemail or connect them to another number.The user may press 2 and then enter another phone number to which they will beconnected free of charge. It may become a hassle for users to dial phone numbers by handevery time they want to make a phone call. Since their introduction, cellphones have alwayshad the ability to have keystroke sequences programmed into telephone numbers stored foraddress book entries.

Two important programming codes available for numbers are the "pause" and the "wait".When a pause is inserted into a phone number, the cellphone will dial the portion of thephone number leading up to the pause. Then for each pause inserted into the stored

number, the phone will wait 2 seconds before continuing on to dial the remaining numbers.When a wait is inserted into a code, the phone will again call the phone number storedahead of the wait code, but instead of waiting a certain amount of time prior to dialing theremaining numbers, the phone will wait for the user to press a key to signify to the phonethat is okay to proceed in dialing the remaining numbers.

iPhone users who want to simplify dialing but weren't able to grab the official Google Voicedialer have another option. There is a free app called Prefix Dialer. The app can beconfigured to automatically prepend a dialing sequence in front of the numbers to be dialedwhen calling an entry in the phone's address book. Once the app is installed, go into thesettings, and enter this special sequence:

Enter your Google Voice phone number, the letter "p", your pin, another letter "p", the

number 2, another "p", and optionally the number 1 (the final "1" seems to speed up dialinga bit, but is not required).

For example, if your GV number is 555-666-7777, and your pin is 9999 then you wouldenter "5556667777p9999p2p1". Then, whenever you want to place a call go into PrefixDialer & tap "select number". The app then shows you your normal iPhone contact list.Select a contact and dial like you normally would. When the call is placed the app will dialyour prefix first, then the number you selected, thus routing the call through your GoogleVoice account.

Separately, there are options for Google Voice users who don't have a smartphone (or adata plan for their smartphone) but still want to enjoy free calling without typing 11 digits

for every outbound call. The solution is to update the phone numbers for each of theircontacts, starting with the most frequently called ones. Instead of just having the person'sphone number listed, the Google Voice user will update the number to read their ownGoogle Voice number, plus either a wait or a long enough series of pauses, the number 2,another pause or two, and finally the number that was originally stored in that memorylocation. This restores even "low tech" Google Voice users' ability to make unlimited freeoutbound calls with little inconvenience.

It should be noted, however, that any frequently called numbers that are on the GoogleVoice user's cellular network should not be changed. As Google Voice is not a cellphone


4/31

service, the parties receiving calls from new Google Voice users will now be chargedminutes to receive phones they have never been charged to receive before.

So by simply adding their own Google Voice number to their "Calling Circle", Google Voiceusers have two options for making unlimited outbound calls without consuming any talkminutes allocated to their account. One way requires a drastic change in the way in which

phone calls are placed by forcing users to visit a website instead of their own local addressbook. The other way either requires a significant amount of extra button presses at the startof each call or the systematic editing of every frequently called number in the user's addressbook that is not a mobile phone on the user's own cellular network.

In addition, Google Voice has an option to further extend the benefits of this approach. Bygoing into the configuration settings of their Google Voice account, users are able to decidewhat is shown on their caller ID when a call arrives through the Google Voice system. Usersmay choose to see the actual caller ID presented by the caller, or simply mask all incomingcalls behind the Google Voice number. When calls arrive on the user's Google Voice line,calls presented to the user with the user's own Google Voice number as the caller ID willcause the user's carrier to recognize that number as being in their calling circle andtherefore free.

There is a third way in which users can enjoy unlimited calling. On select smartphones,particularly those running Google's Android operating system and RIM's Blackberry phones,Google has released software that simplifies outbound dialing. The user brings up analternate dialer, which still typically has access to the user's local address book stored ontheir smartphone. When the user chooses a number to dial, the alternate dialer performstwo steps in parallel. First, the dialer uses the phone's Internet connection to notify GoogleVoice's servers that a call is about to arrive from the user's cellphone and the messageincludes the phone number they are actually trying to reach. Then the dialer triggers thephone to call an entirely different, unpublished number to log into the Google Voice system.Once the Google Voice system has processed the message sent previously by the alternatedialer, the system answers the inbound call coming from the user's cellphone and connectsthe caller to the number they originally specified in the alternate dialer.

This is significant because there's no way for users to know which Google Voice "accessnumber" the user's handset is going to call and yet, this number has to be detected by theuser and added to the user's calling circle. If the user does not figure out this accessnumber and add it to their calling circle, they will be under the misconception thatall of their outbound calls are free, when in fact they are not.

When Google Voice users with calling circles add their Google Voice number (and the accessnumbers used by smartphones) to their calling circle and choose to have Google Voicedisplay their own Google Voice number as the caller ID on incoming calls, they are now ableto make and receive unlimited calls with their cellphones under certain conditions:

1) The cellphone is on their carrier's home network (i.e. not roaming),

2) The user always uses a dialing method that routes calls through the Google Voice serversand all entrance numbers are listed in their calling circle,

3) Parties calling the user call them through their Google Voice number,

4) The user maintains at least the minimum calling plan that qualifies for calling circles

4. Free Calling with Voice Over IP (VOIP) - Introduction

Voice Over Internet Protocol (Voice Over IP, or simply "VOIP") is a generic term that appliesto methods and approaches for allowing users to transmit audio over Internet connections.There are many approaches and technologies applied to implement VOIP, and a fewstandards have been developed to ease the interaction between two or more systemslooking to establish a session. One of the most popular approaches is called SessionInitiation Protocol, or SIP. SIP is able to establish connections covering a variety ofcommunications, but for for the purpose of this discussion, SIP should be thought of as away to link two or more systems together for the purpose of establishing, maintaining, andterminating phone calls. Generally speaking, a SIP server is a system that either connectsto other systems or to end users, either over SIP or through a gateway function that links"digital" phone calls to telephone devices.

What end users tend to think of as a "phone line" can be hosted by a SIP server and linescan be activated or deactivated by an authorized person identified through their logincredentials. Just like how people login to Google's properties to check their Gmail accountfor new email, see their custom dashboard in iGoogle, chat with their friends and family on

Google Talk or read the headlines in Google Reader, users of SIP lines can bring up phonelines by using special software to authenticate against a server using unique credentials.When the SIP phone line is activated by the authorized user, phone calls destined for thatphone line are presented to the end point the user has designated as their personalinterface to the phone line.

Endpoints may take the form of software on a laptop or PC that looks just like a desktoptelephone, software that runs on small, handheld computers the size of a cellphone,software that runs on an actual cellphone or (with the help of another device) a standardtelephone sitting right on their desk. Without getting too far into details, it is just importantto know that what we know as "phone calls" can now freely hop back and forth between theold fashioned wire technology you see in your walls behind the phone plug and computerscommunicating with each other over the Internet. That's how the phone companies have

done it for years, and you are free to join in the fun.

Since long before GrandCentral (the predecessor to Google Voice) hit the scene, serviceshad been popping up, offering low cost phone calls with very low per-minute rates,particularly for international callers. Some companies allowed customers to access theirsystem via regular telephone lines while others only allowed calls to traverse their networkin digital form. Since Google Voice offers publicly accessible phone lines and uses high techapproaches to routing and managing phone calls on those lines, its only appropriate thatGoogle would allow a pure IT-based approach to allowing users to connect to their GoogleVoice phone lines in the same way. And Google did allow this for a short time.

5. The Gizmo5 Project - Background

After a brief period of allowing all users direct access to their Google Voice phone lines viaSIP, Google restricted the purely digital access through an established Internet phone lineprovider, Gizmo5. Now Gizmo5 had its own digital phone line service offering, complete withtheir own domestic and international calling rates. But by accepting digital phone calls fromGoogle Voice and allowing Google Voice users to receive phone calls from Google Voicecompletely free of charge, their revenue model was threatened. Remember, when you enter


7/31

or select a phone number to call on the Google Voice website, Google Voice calls you firstand when you answer, connects you to the other party.

So if Gizmo5 was granting free access to end users to free digital-only phone lines but alsohad the only all-digital path to Google Voice, they were destined to receive a stampede ofnew Google Voice users who had no interest in using their chargeable services.

Furthermore, since Gizmo5 offers free forwarding of inbound calls to other destinations overSIP, this meant that anyone worldwide could suddenly sign up for free services from Gizmo5while waiting for a free phone line from Google Voice. Google worked very hard to limit theearliest eligible beta testers to those located in the US, but Gizmo5 breaks that requirementand will forward your phone calls anywhere in the world over SIP.

After a several months of beta testing, Google recognized that not only does Gizmo5 play akey role in linking some of Google's users with a very popular product, the popularity of theproduct paired up with Gizmo5's generosity was quickly eating away at their bottom line.Instead watching Gizmo5 collapse into itself, taking a successful, established business withit as well as thousands of Google users using Gizmo5's services for free, Google boughtGizmo5 and is currently in the process of rebranding their product line and apparentlypreparing to better integrate the service with Google's offerings.

6. Google Voice Integration with Gizmo5

After a torrid build-up of interest in Gizmo5 as the only provider with SIP access to GoogleVoice, Gizmo5 introduced some integration with Google Voice. Recognizing that GoogleVoice directly competes with and undercuts their long distance calling product, Gizmo5added some configuration settings to the user accounts, allowing users to specify theirGoogle Voice credentials. Then, users would initiate an outbound call through Gizmo5's ownsystems, not Google's. The Gizmo5 servers would then interact with the Google Voiceservers to initiate an outbound call but connect the call to the Gizmo5 user who initiated thecall. Because of the direct competition, Gizmo5 limited calls inititated in this way to 3minutes in length.

Gizmo5 did not limit the length of calls that arrived inbound from the Google Voice servers,however. This means that all calls arriving into Gizmo5 accounts from Google Voice areunlimited in length. Recall that when Google Voice users initiate outbound calls by enteringor selecting phone numbers at the web site, Google Voice always proceeds by calling theuser first at a number they specify, only to connect the user to the desired phone numberwhen they answer the call. From the very beginning, Google Voice users with Gizmo5accounts have been able to make calls of unlimited length over SIP merely by initiating thecalls at the Google Voice website.

Since SIP is a computer-to-computer communication system, this means that users withdevices capable of SIP communication can now enjoy free unlimited calling byauthenticating their SIP client against their SIP account at Gizmo5 and initiating outboundcalls via the Google Voice website and indicating to Google Voice that they can be reachedthrough their Gizmo5 phone line. This also means that devices that have not historicallybeen thought of as telephones can now serve their users in that role.

7. Gizmo5 Integration with SIP Sorcery

Among the many SIP phone line providers on the Internet, SIP Sorcery presents aninteresting end user experience. SIP Sorcery was developed to offer a flexible way to control


8/31

the flow of phone calls while in their digital form. What is unique about SIP Sorcery'sapproach is that they expose a complete programmable environment, allowing skilled usersto develop robust and complex schemes for routing calls between networks. WhenGrandCentral reopened its doors as Google Voice and Google Voice restricted its SIP-basedcommunications to Gizmo5, SIP Sorcery seized a unique opportunity.

See, Gizmo5 still offers to forward all inbound calls to another destination free of charge, solong as the connection is via SIP. This is of no consequence to SIP Sorcery because theyonly deal in SIP links. SIP Sorcery unilaterally updated their system to include support forGoogle Voice. They developed and made available a script function that uses Google Voiceto establish phone calls which are then presented via SIP to SIP Sorcery and on to theirconnected users. SIP Sorcery uses the phone numbers entered via a SIP client to kick offthe script that establishes a call at Google Voice.

What does all this mean? It means that users who connect to SIP Sorcery via SIP areable to dial phone numbers directly in their SIP clients or on their analog phonesattached to a SIP-compatible phone adapter. SIP Sorcery then uses Google Voiceto place unlimited free calls to any US phone number entered by the user.

It also means, by extension, that users who connect their SIP clients directly toGizmo5 or other SIP gateway providers and don't want to pay for their valueadded services are not utilizing the service in the most efficient and cost effectiveway.

8. SIP Sorcery Integration with sipgate

SIP Sorcery is not only able to process and route SIP calls, but is also able to serve as a SIPclient to SIP providers. This capability enables SIP Sorcery users to use any other telecomprovider that offers SIP access to their users' phone lines. Sipgate.com is one such provider.In order to enable 24x7 free calling for Google Voice and sipgate users using just a SIPclient, follow these simple steps to use the dialplan in the next section.

Note: These instructions will be sipgate-specific until Google re-opens Gizmo5 forsignups. If you have a Gizmo5 account already and would like to know how toenable free calling without the 3-minute limit, please ask in the forum until thenew process is known.

1. Sign up for a free Residential Sipgate ONE account at sipgate.com. Go into your settingspage and take note of both your regular phone number (usually in area code 415) as well asyour SIP credentials.

2. Sign up for a free account at SIPSorcery.com. You will need to install Microsoft Silverlightin your browser to perform this step and complete the rest of this process.

3. On the SIP Providers page, add a new provider named "sipgate" and enter your SIPusername and password provided by sipgate. Enter sipgate.com as the server. Click "showadvanced settings" and add sipgate.com as the proxy. Check the "Register" checkbox andmake sure that the registered contact shows "sip:" followed your SIP Sorcery name and"@sipsorcery.com". Click Add when you have finished. After a few seconds, sipgate shouldautomatically appear in the "SIP Provider Registrations" list at the bottom of the screen. If itdoes not, double check the SIP credentials and server settings against those shown on yoursipgate account settings page.


9/31

4. Configure your SIP client, SIP-compatible softphone or SIP-compatible ATA to login toyour sipsorcery account. Check the "SIP Accounts" page of your SIP Sorcery account andmake sure an entry appears in the "SIP Bindings" list at the bottom of the page.

5. Use a phone to call your sipgate number and make sure the phone attached to your SIPSorcery account rings. Answer the call and make sure you can hear sound in both

directions.

6. Login to Google Voice, click Settings, Phones, and add your sipgate phone number as anew managed phone. Google Voice will display a two digit number on your screen. ClickConnect and Google Voice will call your sipgate number and ask you to enter the codedisplayed. Once you successfully add the new line, make sure it is checked on your GoogleVoice phone list.

Note: You are now ready to receive inbound calls to your Google Voice number for free. Youmay also enter phone numbers on the Google Voice website and select your sipgate numberas the phone you wish to use to make free outbound calls. There is one last step required toenable 24x7 free unlimited outbound dialing from your SIP-compatible softphone orstandard telephone attached to your SIP-compatible ATA.

7. Copy the SIP Sorcery dialplan below, go to the Dial Plans page in SIP Sorcery, click ondefault, and paste the dialplan, overwriting the short default script already there. Customizethe portions of the dialplan highlighted in blue below according to section 11. The script willnot function correctly and you will not be able to make free outbound calls until youcustomize all of the highlighted text.

If you've made it here, you should be all set. If you followed all the steps properly, youshould be able to start your SIP client or pick up your ATA-connected phone and dial anynumber in the US for free. If you are unfamiliar with other SIP clients and SIP-compatibledevices available to you, check out Section 12.

NOTE: If you are unable to follow these steps and just can't seem to get outbound dialing to

work, please see section 13 of this document for more detailed instructions, includingscreenshots of the setup process.

9. SIP Sorcery Scripting

Key to taking advantage of SIP Sorcery's capabilities is their scripting feature. It isimportant to remember in all this that SIP is just a method for enabling computers toexchange audio (and other information) in a way that is compatible with what people knowas "telephone calls". The scripts that SIP Sorcery supports are called dialplans. Dialpansinstruct SIP Sorcery on how to route calls based on a variety of parameters. Only outbounddialplans are needed for integration with Google Voice.

10. Unified Dial Plan

Here is a dialplan adaptable to both sipgate and Gizmo5 that offers a speed dial directorythat is accessible from every attached phone. It is also capable of automatic routing acrossmultiple SIP providers based on the phone number you are calling, also developed byMikeTelis at mysipswitch.com. You will need to edit the Google Voice section with yourGoogle Voice username, password, and your assigned sipgate number.

For the code below - entries highlighted in blue need to be modified before saving thedialplan. There are 5 entries that need to be customized and 2 highlighted hash marks ineach of two sections, one of which in each section MUST be removed in order for dialing tofunction.

minute to call your emergency services center ON A NON-EMERGENCY NUMBER and askthem for the best alternative number to call if you don't have 911 service.

URGENT NOTE: It is always best to call 911 from a live phone line provided by the phonecompany. Your second best option is your cellphone, preferably one with GPS functionality.Your very last option should be to use Google Voice to call the alternate number provided to

you by your emergency services center. They will not have automatic addresses or GPScoordinates, so they will have the least amount of information available if you call during anemergency. They will also typically answer 911 calls first so you may not get an immediateresponse when it is most urgently needed.

A popular use for the speed dial directory is to listen to podcasts collected by podcastaggregator Podlinez. They collect thousands of regularly updated podcasts and link them tophone numbers. By calling the assigned phone number, the user will immediately hear thelatest episode of the associated podcast. Podlinez takes the extra step, however, of makingeach and every phone line also available via SIP. This means that SIP Sorcery can beconfigured to call any of those numbers directly over SIP instead of using Google Voice tocall into Podlinez via a standard phone line. And since the speed dial directory supportstranslating short codes to other SIP-accessible phone lines, users are free to choose any

number of podcasts from the Podlinez directory and add them to their speed dial list.

For example, the CNN Radio top stories podcast is updated hourly and available to allphones at 1-415-376-7253. Podlinez also makes that phone number available via SIP at"[email protected]". Instead of dialing the entire number or creating an entry inthe address book for each device attached to your SIP Sorcery account, a "short code"number can be added to the custom speed dial directory at the top of the script. As soon asthe script has been updated, all attached devices can dial the short code and hear theheadlines. Since 266 spells "CNN" on a standard telephone keypad, the short code can beadded to the speed dial directory with this simple line placed in the middle of the directory:

'266' => '[email protected]', # CNN Headlines (266 = "CNN")

Again, all phone numbers listed in the Podlinez directory can be added to the speed dialdirectory by creating an entry formatted like the one above. This is not required as usersare still free to call the traditional phone lines to hear the podcasts, but those lines areoccasionally busy. Accessing the lines via SIP bypasses the traditional phone lines, leavingthem open for other users who are not SIP enabled, and also eliminating the chance ofcalling at a time when the phone lines are simply out of capacity.

12. Connecting other SIP Clients and Devices

The hard part is out of the way! You are now free to connect any SIP client software or SIP-compatible devices to your SIP Sorcery account and enjoy unlimited calling to and from US-based phone numbers. SIP client software is available on many platforms. These include butare not limited to:

sipdroid for use on Android cellphones and Internet tablets iSip for the iPhone and iPod Touch Internet Call for Maemo devices such as the Nokia N810 Internet Tablet SIP Phone (note: Get the real name!) on Symbian cellphones

Many SIP-compatible Analog Telephone Adapters (ATAs) are also able to login to your SIPSorcery account. One popular device is the Linksys PAP2T-NA ATA.

That's it. Hook up a standard analog phone to the Line 1 port on your Linksys device, pickup the phone, and enjoy unlimited calling to and from US-based phone numbers.

If you would like an alternative approach to configuring your Linksys ATA, see theconfiguration wizard available at Voxilla, available here:

http://voxilla.com/voxilla/tools/device-configuration-wizard/linksys-pap2-pap2t-configuration-wizard

1. Connect the Linksys device to an open port on your home router. Attach an analog phone

to line 1. Pick up the phone and dial "****" (Four stars). At the voice prompt, dial "110#"and take down the ATA's IP address that is given to you.

2. Using the Voxilla configuration utility, enter the IP address of the router in Step 1.Choose "SIPphone (STUN)" in Step 2.

15. Revision History

12/04/2009 by norske - updates to the sipgate dialplan highlighted user-specific entries for the dialplan in blue (easier to know exactly what

should be changed to make the dialplan work for the new user) added some speeddial codes (including for 1-800-WEATHERCALL) replaced 747 (gizmo5) area code with 415 (sipgate) in what was line 80 removed (2) # characters that were in front of the following two lines. They were

causing syntax errors in line 80 of the dialplan

when /(800|866|877|888|415)/ # US toll-free and sipgate-to-sipgate callsroute(5,"Destination - US toll-free or sipgate")

12/04/2009 (AM) by EasternPA -

removed 911 from the sipgate and Gizmo5 dialplans until we have a better methodof hosting those life-critical services. Too risky otherwise IMHO.

updated the formatting line for the speed dial sections of sipgate and gizmo5dialplans

replicated the highlighting in the Gizmo5 script copied the new speed dial entries from sipgate to gizmo5. I'm wondering if we

should build a separate section just for the speed dial directory to avoid having toreplicate the entries between the sections. Keep the unique entries in each dialplan,but maintain a separate section for entries that are not unique to the SIP provider.As more SIP providers get added to the doc, it will get messy trying to replicate along directory. That was also my original intention with creating the Wave. A

separate place for a common speed dial directory.norske (6:30p): I agree that the speed dial section can remain fixed as-is. Itprovides plenty of examples for others to tweak their own to suit their specificneeds. Another section would be OK - but especially useful if we have somethingreally useful that may otherwise be tough to find.

12/04/2009 (PM) by EasternPA -

Renamed section 9 to be Gizmo5-specific Made extensive changes to section 10 to account for the recent spate of users

unable to complete the process

12/05/2009 by EasternPA -

Removed all references to the 3-line dialplan. That short dialplan no longer works(even with Gizmo5)

Worked with norske to re-sequence Section 10. We agreed that there should be anearly test to ensure the path from sipgate to SIP Sorcery and the SIP client is upand running. Then the sipgate line should be registered in Google Voice. Then thedialplan should be copied over and customized.

Replaced "your Google Voice number" with ".*" in sipgate dialplan per RedLeatherman


30/31

12/08/2009 by norske (RE: the sipgate plan) Moved all user-required entries to the front-end of the dialplan - so user doesn't

have to make direct entries in the sys.GoogleVoiceCall line Adjusted the sys.GoogleVoiceCall line to accept named parameters from the initial

entry section

Added this bullet 12/10/2009: note the final two parameter on this line of code in the sipgate plan:

sys.GoogleVoiceCall(GV_USER,GV_PASS,SIP_NUMBER,@num,'.*',1,30)

The 1 designates the Phone Type, where 1 = Home, 2 = Mobile, 3 = Work, and 7 =

Gizmo. The default (no entry) is "2". For the sipgate plan, it could be that this

parameter is not an absolute requirement.

The need to add a Phone Type is a recent change.. and is documented here:

http://sipsorcery.codeplex.com/SourceControl/PatchList.aspx

With respect to the final parameter - it's the "callback timeout"in seconds which is the

amount of time the sipsorcery dialplan will wait for the GoogleVoice callback before giving up

and continuing with the next dialplan command. The timeout must be between 5 and 60s and if

not specified a default value of 30s is used."

I think that if you're OK with the default, then an entry isn't mandatory.

Here's a link to sipsorcery's dialplan help.. it's tough to read because of the graybackground, but it does explain key parameters used in the dialplans.

https://www.sipsorcery.com/help/dialplans.html

12/09/2009 by norske reposted the latest EasternPA document - that link was having issues this morning fixed a couple of formatting issues (things bold and larger font than they're

supposed to be)

12/10/2009 by EasternPA reformatted the new user credentials area at the top of the sipgate script (a few

lines were line-wrapped) updated the comments in the Google Voice section of the sipgate script since users

no longer need to enter their credentials in that section of the dialplan anymore

12/10/2009 by norskerevised the gizmo dialplan to match the change I made to the sipgate plan on 12/08/2009as outlined above... namely:

Moved all user-required entries to the front-end of the dialplan - so user doesn'thave to make direct entries in the sys.GoogleVoiceCall line

Adjusted the sys.GoogleVoiceCall line to accept named parameters from the initialentry section

31/31

12/11/2009 (AM) by EasternPAMade MAJOR changes throughout the document. I created a new unified dialplan that isportable to users of both Gizmo5 and sipgate. Every section from 7 on has been edited,moved, or deleted. There are now two sets of two commented lines in the mandatoryediting section and one line in each set must be uncommented based upon the provider the

user has selected. I also nullified the checks for the AK, HI, Yukon, and toll free numberssince they are all properly handled by GV. I left the original code in place as comments incase anyone wants to experiment with it. One such change would be to specifically route747 calls over Gizmo5, but only if a Gizmo5 account exists.

12/11/2009 (PM) by EasternPAMade another round of major changes. I have incorporated most of norske's screenshots aswell as those provided by jamesgwvoice. I also resequenced the screenshots. For the userswho are able to successfully follow the sequence straight through and can make calls via X-Lite by the end of section 11, they will see the screenshots for configuring the Linksys ATA.

For those users who aren't able to follow the steps in sections 8-11, they are referred tosection 13 for a more detailed set of instructions, including screenshots walking them

through the entire process.

12/12/2009 by norske Added links to the front section of Section 12:
