A method of processing data in relation to a teleconference service in a telecommunications network is provided. The teleconference service is able to handle a multi-party teleconference for three or more teleconference participants. First, second and third teleconference participation identifiers are received from first, second and third teleconference participants respectively. The first, second and third teleconference participation identifiers are correlated to determine that the first, second and third teleconference participants are participants in a given multi-party teleconference. Data is transmitted for enabling the establishment of a data communications session which is established separately from the teleconference. The data communications session is for the communication of data between a first data communication device associated with the first teleconference participant, a second data communication device associated with the second teleconference participant and a third data communication device associated with the third teleconference participant.
