Abstract

See full text

Measures are provided for use in establishing a telephony session between first and second telephony devices in a telephony network. Telephony network equipment in the telephony network receives, from the first telephony device over a signalling link, a telephony session establishment request. The telephony network equipment receives, from the first telephony device over a data link that is separate to the signalling link, a message comprising data useable by the telephony network equipment to identify the second telephony device. The telephony network equipment correlates the received telephony session establishment request and the received message. The telephony network equipment transmits, to the second telephony device, a telephony session establishment request on the basis of the correlating. The first telephony device is associated with a multi-persona user having a first persona associated with a first telephony identifier and a second persona associated with a second telephony identifier.
