Abstract text

A method of recording at least a part of a conversation between a plurality of conversation parties, wherein said conversation is enabled by establishing a call through a circuit switched telecommunications network. Said at least one part of said conversation is recorded in a data file using a recording system which is located in the network at a central location, and said recording is controlled by control signals provided to said recording system through a packet switched telecommunications network by at least one of said conversation parties. Said control signals identify said call for associating said control signals with said conversation. By providing the control through the packet network no DTMF tones need to interrupt the ongoing conversation to start and stop recording using access codes which also means that no monitoring circuit need continually be inserted in the voice path. Thus control of the recording is provided using an IP based interface rather than via the circuit switched path.
