<p>The invention discloses a system whereby an endpoint device can transfer/forward an ongoing session to another endpoint device, typically one also associated with the user of the original endpoint device. Alternatively endpoint devices can be added to the session (e.g. for conferencing) and devices may belong to one of a group of users. The original device may use an SIP REFER message to direct the remote communication endpoint to establish a session with the new device. The original endpoint device may periodically interrogate the local network to discover and authenticate other potential endpoint devices (see Figs. 3a,3b). The resulting list of devices may be presented to the user via a UI menu to allow selection of transferee devices (see Fig. 4).</p> |
