The historical telecommunications network (PSTN), the one we have been using since the 1970s and which is still used by most companies, will gradually be phased out in France, as in other European countries.

Essentially, this means that by 2020 it will no longer be possible to create new analogue and digital lines; and in the long term, by 2022, companies that currently have their systems on this network will have to switch to new technologies.

The main reason for this technical discontinuation is the obsolescence of specific equipment and components, as well as the increasing difficulty in maintaining them.

It is crucial for today's companies to anticipate this PSTN shutdown, and to switch their phone networks to IP solutions.

By pooling phone and Internet access services on the same network, companies can simplify their network, benefit from real savings and take advantage of the new collaborative tools available with the next-generation solutions: instant messaging, videoconferencing, availability management, and so on.

So it's important to understand now the issues involved in the transition to VoIP, and to choose the telecom service that best meets your company's needs.


What is VoIP?

VoIP, or Voice over Internet Protocol, is a technology that allows the Internet to be used for telecommunications purposes. Simply put, it means using a high-speed Internet connection to make phone calls.


In practice, what difference does it make to you?

VoIP solutions offer companies a number of advantages over PSTN based services.


Cost reduction

Switching to VoIP will save your company money with much lower communication costs: the cost of outgoing calls is lower than PSTN technology, especially for international calls.

VoIP also makes multi-site management possible: calls between sites are free and require only one Internet subscription.


More flexibility for the company

Using IP technology, a company will be able to add extensions or users to its network easily and at no cost. Business development processes are made much easier, resulting in significant efficiency and productivity gains for companies.


New functionalities

VoIP allows companies to benefit from next-generation telephone functionalities: call forwarding, on-hold music, virtual fax, etc.


Now that you are confident about the benefits of switching to VoIP, it's important to take a look at your company's requirements in order to choose the solution that will best meet your needs:

  • What are your company's call behaviours? Do you make many international calls? To mobiles?
  • Which telephone services are essential for your company (line grouping, filtering, special numbers, etc.)?
  • Does your company use software that could be integrated into your telecoms solution (CRM, business software, etc.)?


What are the alternatives?


SIP Trunk

SIP Trunk is a service that allows a company to make simultaneous calls over its Internet network. A SIP Trunk features a number of "channels", and therefore of simultaneously available telephone connections. These simultaneous communications can range from 2 to more than 60 depending on the company's internet connection.

The main advantages of the SIP Trunk are cost reduction and flexibility.

Companies save money on their telephone subscriptions, and can make unlimited calls to landlines and mobiles. They are also very flexible when it comes to adding or deleting telephone lines at any time.

Unified Communications

Unified Communications are next-generation solutions that allow users to access new tools to communicate better, or communicate differently.

They are designed as software to bring together the various devices available to users: landlines, smartphones, computers - to enable them to work in sync with each other. Users are therefore more independent and mobile, while benefiting from multimedia tools that are perfectly synchronized on their various devices.

Users are freed from the constraints of traditional telephones, and take their company telephone wherever they go: meetings, travelling, in the home office, they no longer miss any calls and work as if they were at their workstation at any time of the day.

With Unified Communications solutions, collaboration is at the heart of the company strategy thanks to the wide range of functionalities made available to users (video, conference call, instant messaging, etc.).
