[OpenSIPS-Users] Re-transmission on TCP leg

[Govindaraj, Rajesh]

Hello everyone,

We are using opensips 2.4.4. One of our use cases needed us to use opensips in a stateful manner and we are using t_relay API.

We find that in a TCP sip session established between opensips and one of our endpoints, (the session created with t_relay) Requests(Non-Invite requests) are re-transmitted.
As part of the test, we were deliberately delaying the response to the request to mimic real world scenario.

RFC 3261 is hazy but specifies for unreliable transports re-transmission should be triggered,(doesn't say anything for reliable transports)
Is this expected behaviour of opensips or is it something that can be configured?

Highly appreciate your help. Thanks for your time.
