IP telephony: everything you need to know about all-in-one telephony!

Are you wondering what IP telephony is? Otherwise known as VoIP telephony, it is a computer technology that allows voice calls to be made via a broadband internet connection, rather than via a traditional line.

This is a revolution in the world of telephony and particularly for business telephony. The number of VoIP subscriptions has increased by 3 million in one year, while the number of PSTN (Public Switched Telephone Network) subscriptions continues to decrease.

IP internet telephony seems to have a bright future ahead of it, and that is for the good of companies!

A look at this technology that sometimes lacks visibility.

Internet telephony: from PSTN to VoIP


The Public Switched Telephone Network (PSTN) is the first generation and historical network for fixed telephones. In an increasingly connected and fast-paced world, this so-called analogue network has quickly come up against its own limitations.

This is how IP telephony came about and is replacing the PSTN today.

IP telephony or VoIP is characterised by the meeting of the telephone and the internet. Faster, more interconnected and more efficient, telephone systems with VoIP technology, based on the SIP open standard, allow new functionalities such as sending videos, faxes, messages, etc.

And this new technology is primarily for the benefit of businesses.

Digital transformation of companies thanks to professional telephony


By rethinking their telephony, companies are giving new impetus to collaborative work within their teams and to their customer services.

In fact, professional IP telephony based on the SIP protocol, in addition to allowing the exchange of traditional voice, offers the possibility of making calls by videoconference, sharing documents, communicating by instant messaging, etc.

This transfer of telephony from the analogue world to the digital world marks a considerable evolution: that of the generalisation of communications via the Internet. This is why a company that wants to evolve in a more connected world must also necessarily carry out its digital transformation.

Depending on the company's needs, professional IP telephony can :

  • provide for several communications at the same time, and with the same number (which was not possible with the PSTN),
  • receive and make calls from a simple computer (landline, laptop, smartphone),
  • carry out instant messaging or video telephony.

These multi-channel lines are an advantage for a company:

  • If they are looking to make outbound prospecting calls, then they may also receive calls from customers with the same number.
  • If it launches a marketing campaign, it will not miss any customer calls, and customers will not find the lines busy.
