I would take a look at the contact header in the INVITE and both PRACKs.

Yes, the only things that's different is the branch-id in the Via header.
And the RAck sequence number in the PRACK for the 180. That's 0 1
because there's no RSeq to copy from. I suspect that's the problem,
and the PBX is the problem here, but I'm not sure.

I'd have to dig up the RFC for PRACKs to comment on that. If the problem is at
that level though, I don't believe that a 481 response is quite right.

Is this assumption correct:
If UAC sends 100rel required, then UAC controls PRACK.
If UAS sends 100rel supported, then UAS controls PRACK by sending
100rel required with proper RSeq?
If that's correct I think the PBX is the problem here by sending PRACK
to the 180 ringing.
The 180 ringing only

The provisional response to be sent reliably is constructed by the
UAS core according to the procedures of Section 8.2.6 of RFC 3261.
In addition, it MUST contain a Require header field containing the
option tag 100rel, and MUST include an RSeq header
Thanks guys for confirming this!
I will have a chat with the PBX guys instead =)

Hi,

returning 481 is correct.
