[SR-Users] suppress t1 timer retransmissions?

[Brooks Bridges]

Correct.  This is an http interface for getting data, and the UAC is doing dumb things where it's sending an invite, then an ACK 2ms later, and then waiting on the response.  It never replies to the response, so the proxy retransmits several times which overloads the requesting system.

I'm trying to find a way to make t_reply() act like sl_send_reply() when sending a message and do not retransmit if it doesn't get an ACK.

Oh, I see. You mean you don’t to forward retransmitted replies from upstream?

In the previous iteration of this platform it was fine since I was using a stateless reply, so even though it wasn't "right" it still worked out.  I need to replicate this behavior in the event route for http_async_client(), which prevents me from being able to use t_release().
