Call recording in a telecommunications network

摘要

A method of recording media transmitted to or from a first party communicating through one of a plurality of mobile telecommunications networks with a second party is described. Either the first party or the second party initiates a call with the other party. One of a set of call splitters distributed through the plurality of telecommunications networks is then determined to be a local call splitter to one of the parties. A connection is then established between the first party and the local call splitter to split the call into a recording part and a call part. The call part is routed between the first party and the second party via the call splitter to provide transmission of media between the first party and the second party, and the recording part is provided by the local call splitter to a recording service associated with the first party. Suitable apparatus is also described, as are methods for recording the calls of a subscriber to a central recording station using a network trigger set or a SIM application set to divert the call to a recording node.
