[OpenSIPS-Users] OPTIONS over TCP

[Vincent DOCQUOIS]

Hi Bogdan,

Thank you for your answer. 
In fact it is the gateway of one of our customer that we can't change configuration and it is not sending OPTIONS with "transport=tcp" in headers.

Regards

Vincent

> 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) :
