<p><font size="-1">I have just upgraded to Opensips 2.2.1 to
take advantage of the new dialog reinvite ping, but what
I am seeing is every time my Opensips proxy sends an
invite ping the UAC (tried polycom and Yealink phones)
responds with a 500 Internal Server Error. I can't see
anything wrong with the invite packet that Opensips is
sending out. Any ideas how I can diagnose this further?</font><br>
