Hi Alex, Since release 0.8.0, we have a feature to automatically update the registration if the Contact address is different than the Via received/rport value. Have a look at http://trac.pjsip.org/repos/ticket/381 This works fine with most servers so far, and it should. Could it be that your server doesn't like this?
