ESTABLISHING A TELEPHONY SESSION

Measures are provided for use in establishing a telephony session between first and second telephony devices in a telephony network. The first telephony device is associated with a multi-persona user having first and second personas. Telephony network equipment in the telephony network: (i) receives, from the second telephony device, a telephony session establishment request relating to the second persona; (ii) transmits, to the first telephony device over a signalling link, a telephony session establishment request, the telephony session establishment request comprising a first telephony identifier associated with the first persona; and (iii) transmits, to the first telephony device via a data link that is separate to the signalling link, a message comprising: (a) data useable by the first telephony device to determine that the transmitted telephony session establishment request relates to the second persona; and/or (b) data useable by the first telephony device to identify the second telephony device.
