I replied hastily. ACK must indeed have the same credentials as INVITE.

The call flows RFC (RFC 3665) also has an example (3.3) where it shows the ACK to duplicate the headers from the INVITE...

This is because the nc value will be incremented and the method name is different. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, February 25, 2004 10:36 PM To: Roman Shpount Cc: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: [Sip-implementors] Credentials in ACK Hi Roman, It should be exactly the same as the original INVITE - it need not be recomputed using the ACK method. Ref Section 22.1 of the RFC: "UACs creating an ACK message will duplicate all of the Authorization and Proxy-Authorization header field values that appeared in the INVITE to which the ACK corresponds."

In case of digest authentication, should those credentials be exactly the same as the ones in the original INVITE, or should they be re-generated for ACK method? ___________________________________ Roman Shpount, VP of Technology aTelo, Inc. -- www.atelo.com _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
