Abstract
Measures for use in processing communication sessions in a telecommunications network are provided. Each communication session has a signaling path spanning a plurality of devices including one or more intermediate network devices and at least two endpoint devices, the signaling path comprising a plurality of signaling segments, each segment being between two devices in the plurality of devices. A first signaling message, comprising a first identifier associated with the communication session, is received via a first signaling segment for a communication session. At least part of the first identifier is transformed using a deterministic encryption algorithm to generate a second identifier. A second signaling message, comprising the second identifier, is transmitted via a second signaling segment for the communication session to associate the second identifier with the communication session.
