Dear SIP Gurus, I was wonder if anyone might have some guidance and/or references for developing a fault tolerant UA that could handle a failover from one server to another in the middle of an existing dialog. I'm planning on using UDP as transport so there are no connection issues to worry about. As long as I've captured sufficient state information to uniquely identify the dialog (from tag, to tag and call id) it seems like I should be able to reconstitute it on another machine under a new UA. My biggest unknown is if changing the IP address that a new request originates from for an existing dialog will cause the remote side any problems. Also, can I use a re-INVITE to modify the Contact header to make sure subsequent requests from the other side go to the right address?
