Hi,
In a SIP environment with SIP end points (UAC, UAS) and several SIP
proxy hubs including openSER, is each hub like openSER supposed to
reply with an ACK to 200 OK
the proxy should reply with ACK only to negative replies of INVITE
(hop-by-hop ACK) - for 200OK, the ACK is within DIALOG and should be
generated by the caller (the 3-way handshake to initiate the call).
and BYE messages coming from end points? (i.e. openSER
should stay on
the call) Or each hub supposed to only propagate all messages
including ACKs ?
The proxy must propagate the BYE (no reply to BYE) and ACKs for
200ok.
Cheers,
Daniel
