Hi,
I have a basic sip question. What's the correct r-uri for ACK? I use
stateful forwarding, so all SIP messages pass through ser. I have seen two
types of UA. Some use the contact field of 200 OK response as the r-uri and
other use the original r-uri for INVITE.
Is it a SIP violation to use the original r-uri of INVITE? The problem here
is that if there is a parallel forking for the INVITE, it might be sent to
places other than the real callee.
Any comment?
Thanks,
Richard
