Slide 3
Who is Kool Smiles PC?
• Kool Smiles PC is a network of local dental offices with a mission to expand access to high quality dental care to underserved children and young adults
- Achieved significant ROI and payback in 12 months with a 40% reduction in recurring telephony costs
- Accomplished through an IP-PBX upgrade and a SIP trunking deployment with InGate Systems and Bandwidth.com throughout all offices and the centralized call center
• What is SIP Trunking?
- SIP lines are JUST LIKE T1 lines or POTs lines to the end-user… except better !
They use the VoIP Protocol and are provided by an ITSP instead of a LEC
You don’t have to buy them in chunks of 23 channels anymore
They don’t have the same cost structure or geographic restrictions as legacy telephony
Slide 4
Kool Smiles Environment before SIP
• Kool Smiles in late 2007…
- Growing company
- Old style TDM PBX from 3COM fully deployed but lacking features of the newer IP PBX systems
No global address book and distribution lists
No fully redundant configurations : 5-9s of reliability
No unified messaging or hot desking
No centralized management
- Telecommunications costs escalating and taking on a bigger percentage of the IT OpEx budget
POTs lines at the locations….
T1s and long distance in the call center…
- IT Budget constraints and headcount pressure starting in 2008
Slide 5
The SIP Solution to Multiple Problems
We needed a solution for less headcount, more PBX functionality and less cost ! ? !
Enter SIP Trunking… Just like a phone line, but 40%-60% less !
• Upgrade proposal to Executive Management
- Evaluate offerings from Phone Equipment vendors
- Evaluate offerings from ITSP vendors and ongoing cost savings
- Purchase new Enterprise phone system centralized components and phone lines
- Create connectivity between the new system and existing NBX platform
- Stage each location to be trained and migrated to the new system
- Port phone numbers and consolidate/eliminate un-needed circuits
• Benefits
- 40-60% per year voice telecom cost savings (reduced costs and reduced lines)
- Reduced downtime
- Eliminate scalability concerns (10,000+ users)
- Feature rich enterprise phone system – better communications
- Lower administrative costs – reduce IT headcount
Slide 6
The Partner Search…
• Categories to rate vendor solutions
- Existing customer base with similar deployments and good references
- Unified messaging, find me - follow me, teleworker, ease of use
- Reliability, high availability, scalability (10,000+ users)
- Centralized management, SIP interoperability, standards and security
- Re-use of existing equipment, capex requirements, install complexity
- Business disruption risk
• Equipment and ITSP service interoperability and security was a key concern
- The SIP Trunk solution required some middleware to accomplish all the signaling and security that we needed
- InGate systems fit perfectly because of their partnership with our preferred IP PBX Vendor and preferred SIP trunking provider

Lessons Learned
• Porting existing phone numbers
- Make sure your account is in good standing and completely paid up before issuing any port requests
- Notify the losing LEC that the number will be porting and authorize it
- Be extra careful if you are moving numbers from a non-facilities based LEC
• Check your existing telecom contracts for terms and auto-renewal language
• Having QoS on your data network will greatly decrease the probability of voice quality problems
• Having robust bandwidth in between your IP PBX and the SIP trunking ITSP will also decrease the probability of voice quality problems
• G.729 Codec should be used because of the decreased bandwidth requirements
• Plan out your E911 capabilities and test calls to the public safety providers to test the ANI/ALI delivery is correct for each location
• Select equipment and services providers that have a proven track record and can provide good reference accounts and great customer service
- 5,000,000+ calls since 2/2008 with very few issues
