Generate its own Call-ID ) and forward the INVITE to the server. What if the server challenges such an INVITE ( or REGISTER for that matter ) and the B2BUA does not want to store the auth credentials of the client ? Can the B2BUA act as a pass-through and forward the challenge received from server to the client ? ->. no it can't do so as the response from server with challenge will be actually meant for the B2BUA( not for the client), it's the responsibility of B2BUA to reconstruct the response with the CallID, to and from header as received from the Client. Actually the server will never know from where the request is actually coming i.e the Client. ie. The message sent back to the client will have a different call-id from that of the message in which the challenge was received ? ->. The callID and other fields(like to and from) match will be done by B2BUA by reconstructing the response for the Client. -Regards Asheesh. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
