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.
