Abstract: A method of operating a user terminal in a telecommunications network. A telephony call is established between a first user, associated with the user terminal, and a remote user. Data communications is conducted between the user terminal and a communications server, such that the user terminal has a first connection to a communications session associated with a communications server. The telephony call is manipulated such that the telephony call forms a second connection to the communications session. Both the first connection and the second connection are maintained, for conducting communications between the first user and the remote user. The second connection may be terminated after assessment is made that the first connection is likely to provide better quality of service.
