The credentials for ACK will be different from that for the INVITE. This is because the nc value will be incremented and the method name is different.

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
