Is there any generalized technique for "handoff", for moving a SIP dialog from one interface/medium to another?
My impression is that this problem is most commonly seen switching between a mobile connection and a WiFi connection, but it can happen in pure-SIP situations as well. So far, it seems that a UA could use INVITE-with-Replaces (sent from the new interface to the other party) to transfer the dialog from its old interface to its new interface. Has anyone implemented such a technique?
