I think that it is considered an abnormal situation without the use of http://www.ietf.org/internet-drafts/draft-ietf-sip-refer-with-norefersub-01. txt. Thus the "subscriber" can wait around however long it desires. If the call has been released and no NOTIFY has been received within a minute, I doubt that a NOTIFY is going to arrive. _______________________________________________ Sip-implementors mailing list [email protected] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
