1. A method of establishing a communications session for communication of data with respect to a first telephony user device and a second telephony user device in a data communications network, the method comprising:
at said first telephony user device conducting communications with a server system; transmitting at least one client-server connection request to the server system in said communications and establishing a client-server connection with the server system; and transmitting call party details of a telephone call from said first telephony user device to the server system in said communications, the telephone call involving at least said first telephony user device and said second telephony user device, said call party details including a first identity associated with said first telephony user device and a second identity associated with said second telephony user device, wherein said call party details allow the server system to establish a communications session between the first telephony user device and the second telephony user device whilst the telephone call is in progress, the communications session being separate from said telephone call and for transmission of data between said first telephony user device and said second telephony user device via the server system, wherein the separate communications session is continued in parallel with said telephone call, such that voice call data is transmitted and received between the first telephony user device and the second telephony user device via said telephone call and other data may be transmitted and received between said first telephony user device and said second telephony user device via the separate communications session, and wherein the method comprises receiving a message from the server system to keep said client-server connection alive when said telephone call lasts more than a connection threshold period.
