Abstract
A method of establishing a communications session for data with respect to at least two user devices in a packet switched communications network in parallel to a voice session via a circuit switched network. Call party details of a telephony call are received. The telephony call involves at least a first telephony user device and a second telephony user device. The call party details include a first identity associated with the first telephony user device and a second identity associated with the second telephony user device. A separate communications session is established on the basis of the first and second identities received in the call party details and depending on the capabilities of the user devices. The communications session is separate from the telephone call, for the communication of data to and/or from at least two user devices.
