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?

I'm not sure I follow how that would behave differently? The transaction already
exists as it's a result route for a suspended http_async_client request, the problem
is that the far side is not responding correctly, so I end up with several retransmissions
when I try to reply with a message.

Might this be what you’re after?

So I have a very odd situation that requires me to suppress retransmissions when using
t_reply() to send a response back to a UAC that is horribly broken but I'm stuck with
for the time being. 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().
Anyone have any clever ideas?
