Hello,
you can use t_relay() instead of forward() and that should get you
going. It is how most of the deployments are done out there.
I will have to check the specs if they refer to stateless or
transactional proxy.
As I said, a stateless proxy doesn't keep anything about the invite or
its responses when the ack is processed.
Cheers,
Daniel

Hello,
It's must as per 8.1.1.7
===
The branch parameter value MUST be unique across space and time for
all requests sent by the UA. The exceptions to this rule are CANCEL
and ACK for non-2xx responses. As discussed below, a CANCEL request
will have the same value of the branch parameter as the request it
cancels. As discussed in Section 17.1.1.3, an ACK for a non-2xx
response will also have the same branch ID as the INVITE whose
response it acknowledges.
===
I have seen successful calls made by colleague so definitely errors in
my config or different version.
I hope later this evening to see the differences between our scripts.

Hello,
I haven't looked at specs: is there a requirement that the branch for
ACK of negative replies to be same as for INVITE for a stateless proxy?
A stateless proxy forgets everything about the INVITE as soon as it
sends it out and start processing the next request.
Eventually we can look at the code and see if we can use the same
algorithm to generate the branch value.
Cheers,
Daniel

Hello,
I'm trying to build pretty simple stateless proxy to stay between
gw and
softswitch. Most working properly but not for non200 ACKs.
For some reason softswitch not accepting my ACK.
Trace (note different branch in top Via for INVITE and ACK towards
switch)

I'm pretty new to this so believe doing something wrong.
