A method for transferring a communication session between a source user device and a target user device in a communication network, where the communication session is established between the source user device and a server is proposed. An identifier of a user device is determined. A session modification request is then sent from the source user device to the server, where the request includes the identifier of the target user device. A capability of the target user device to handle the communication session is then checked. Next, if the target user device is capable of handling the communication session a further communication session between the server and the target user device is established.

Method for transferring a communication session between devices

A first user device establishes a video telephony session with a second user device over a best effort network. The voice quality for the video telephony session is upgraded by establishing a voice call with the second user device over a telephony network providing a quality of service guarantee for the voice call, and coupling the voice call over the telephony network with the video telephony session.
