<p><font size="-1">I wonder if any Opensips experts and shed any
light on this.</font></p>
<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>
