Numeris to IP transition
Updating your
corporate telephony

The telephone network is the world’s largest communications network. Initially operated on the analogue PSTN network, IP telephony is now emerging as the new standard for business telephony.

Anticipating your telephony migration

To understand the importance of this migration, we need to go back to the origins of telephony. Historically, the history of telephony began with so-called analogue lines. At that time, communications were routed via the switched telephone network (PSTN), symbolised by the famous “T” socket.

But analogue telephony in the workplace had a number of drawbacks: all calls had to go through the switchboard, and there was only one call per line at a time…

This is how ISDN (Integrated Services Digital Network) technology came into being. This system continues to use the traditional telephone network, but the difference lies in the signal received: with PSTN, the analogue signal is transformed into a digital signal by a modem, whereas with ISDN it is natively digital.

Numeris offers major advantages for business telephony: individualisation of DIDs, presentation of incoming calls, call forwarding, etc.

VoIP telephony, the new generation

With the rise of Internet connectivity, VoIP telephony, also known as Internet telephony or IP telephony (Internet Protocol), is gradually replacing PSTN and ISDN.

In concrete terms, communications now go through the computer network, based on Internet links: ADSL, xDSL, optical fibre.

This architecture not only carries voice, but also data and video.
