One of destination gateways is only handling SIP over TCP. By adding "transport=tcp" header, I have no problem to use Opensips as a UDP to TCP gateway but I encounter 2 problems with keepalive process (using OPTIONS method) :<br><br>1) Is there a way to make DR module send OPTIONS over TCP instead of default UDP ?<br>2) In the opposite direction, when an incoming TCP OPTIONS is received by Opensips from the external gateway, the 'is_from_gw' function seems not to be able to identify my external gateway. Note that it is OK in UDP with another gateway.<br><br>Is it just a limitation or is there any solution to handle OPTIONS over TCP ?<br><br>Thanks in advance<br><br>Vincent<br>_______________________________________________<br>Users mailing list<br><a href="mailto:Users@lists.opensips.org">Users@lists.opensips.org</a><br>http://lists.opensips.org/cgi-bin/mailman/listinfo/users<br></users@lists.opensips.org></v.docquois.netvisio@gmail.com></div></blockquote></div><br></div></body>
