Hi all, I have quick query RFC 6432. RFC 6432 defines carrying q.850 codes Reason Header. As per RFC 3326 the Reason Header Field follows the standard SIP parameter syntax
Reason = "Reason" HCOLON reason-value *(COMMA reason-value) reason-value = protocol *(SEMI reason-params) protocol = "SIP" / "Q.850" / token reason-params = protocol-cause / reason-text / reason-extension protocol-cause = "cause" EQUAL cause cause = 1*DIGIT reason-text = "text" EQUAL quoted-string reason-extension = generic-param The Reason Header carrying q.850 codes indicates only q.850 Cause Code and a reason text. Reason: Q.850 ;cause=16 ;text="Terminated" Q.850 also indicates location field that indicates the point of failure 0 user (U) 1 private network serving the local user (LPN) 2 public network serving the local user (LN) 3 transit network (TN) 4 public network serving the remote user (RLN) 5 private network serving the remote user (RPN)7 international network (INTL) _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
