Fixed telephony traffic has been is steadily declining since liberalisation in 1998. The phenomenon of substitution between "fixed networks" and "mobile networks" continues and explains, in large part, this decline. The number of calls, their duration and their average duration broken down into different categories is shown below.

- Voice over Internet Protocol (VoIP) is a generic name defining the transportation of voice traffic using packets on the Internet Protocol (IP). VoIP traffic can be routed on a controlled private network or the public internet or a combination of the two.
Our statistics collect information (contracts, number and duration of calls) on customers accessing a telephony service via VoIP access provided by a telecommunications service provider. Other forms of VoIP cannot be collected by our statistics, e.g. PC to PC (Peer to Peer) where it is sufficient to download the appropriate program on the internet and make contact with a peer who has installed the same program.
