Migration from PSTN to VoIP
How to transition to VoIP smoothly, painlessly and before it’s too late
WHITE PAPER
Replacing the company phone system can seem a frightening prospect, since telephone
communication is an essential tool we use in our daily work life. As long as the old phone
system continues to function, we prefer not to touch it, and it’s understandable. But whether
you like it or not, it’s time to consider the change.
Most companies in Europe have already completed the transition or are planning it over the
next few years. Switching from traditional phone system to VoIP PBX is more than just a
technological necessity, but a functional requirement.
Why should your business switch to VoIP?
One of the major US telecom providers Verizon stopped offering ISDN to new business
customers in 2013. The same is now happening in Europe: by 2017 the major providers such as
Deutsche Telecom, BT, France Télécom, Telecom Italia will stop offering ISDN lines. Telecom
companies have announced complete phase out of PSTN and ISDN over the next ten years.
The message is clear: PSTN and ISDN technologies have now become obsolete, transition
is inevitable. Besides an outdated telephony system can be one of the biggest obstacles
holding your business back from growing.

WHITE PAPER
What are the advantages of switching to VoIP?
Top 7 benefits of moving to VoIP system:
- Significant cost savings on call rates, including international calls; free of charge calls
between the offices (including international offices).
- VoIP system is easier to install, to configure, to troubleshoot and it can be managed via a
web-based user interface.
- Eliminate unnecessary hardware such as media gateways; as an option it is possible to
install a virtual or a Cloud-based PBX and use softphones instead of SIP phones.
- VoIP system is easy to scale: you can dynamically add and remove lines or reassign
phones.
- Mobility: employees can be reached at the same phone number on multiple devices
wherever they go.
- Portability: you can move your office without changing the phone number or having to
pay for call forwarding.
- Advanced Unified Communication features that improve collaboration within the teams
and enhance the customer service experience.
Can I move to VoIP smoothly and without interruption of phone service?
Depending on the company size, migration times can differ, however the steps of VoIP
deployment are the same, not depending on the company size.
They distinguish five major stages of migration:
● Step 01: Choosing the right vendor
● Step 02: Analysis of company needs and existing infrastructure
● Step 03: Testing
● Step 04: Migration of equipment and services
● Step 05: Removing the old infrastructure

Let take a look into each stage
STEP 01: Choosing the right PBX vendor
Three most common mistakes to avoid while choosing the PBX:
- Mistake 1: Choosing an obsolete system. Choose the vendor that looks into the future
and invests in development and innovation. Evaluate your current needs but also
consider the features that may become necessary in the future, such as WebRTC or
videoconferencing.
- Mistake 2: Choosing an unreliable solution. Some vendors offer systems based on open
source solutions put together. We know that also the major technology companies
develop their solutions based on open source. However it is one thing to “put together”
and it is entirely a different thing to develop. Such solutions are less expensive but they
are characterized by lack of flexibility and reliability.
- Mistake 3: Choosing an incomplete solution. Go for a vendor that offers both Hardware
and Software and works on the integration of third-party solutions and products. This
helps you to avoid problems of third-party products compatibility.
STEP 02: Analysis of company needs and existing infrastructure
Once you have chosen the vendor and the provider, the next step is the site audit and survey.
At this stage it is necessary to conduct a network assessment and to analyze your company LAN
in order to determine whether any eventual upgrades are needed: when it comes to VoIP,
network latency can result in low call quality and dropped calls.
Then you must decide the deployment model. Most vendors offer on-premise physical or virtual
PBX, or a Cloud-based system. Each deployment model has its peculiarities and it’s important to
evaluate which one is better for your business.
It is also important to analyze the existing infrastructure, the needs of your company in general
and separate departments or employees in particular.

STEP 03: Testing
At this point, your old legacy PBX is connected to the new VoIP PBX to ensure the continuity of
all the services and communication.
At this stage you can discover all the advantages of VoIP and Unified Communication &
Collaboration features and make sure the system is right for you and meets your needs.
STEP 04: Migration of equipment and services
Once the testing phase is over, one should proceed with upgrading all the services and the
equipment.
You can continue using analog and ISDN lines before they phase out. As an option, you can still
make use of analog phones and fax machines thanks to FXS media gateways (take into account
that response groups configurations require special attention and it’s recommended to
substitute all the phones belonging to the same response group at a time).
However the power of the system is also in its integrity. By using all the components of the
Unified Communication system such as web applications for collaboration, desk phones, DECT
handsets, smartphone apps, you make sure to take the most of your new VoIP PBX and to see
the results immediately.
STEP 05: Removing the old infrastructure
Once the migration is completed, the old communication system and other unnecessary
hardware can be removed.
