Hello all,<br>
<br>
I am using Opensips 1.10 for SIP trunking purposes.<br>
I use DR module in order to route calls to external gateways. 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>
