The SIP Reason header field is defined to carry ISUP (ISDN User Part)
cause values as well as SIP response codes.  Some services in SIP
networks may need to know the ISUP location where the call was
released in the PSTN (Public Switched Telephone Network) to correctly
interpret the reason of release.  This document updates RFC 3326 by
adding a location parameter for this purpose.

This document is a product of the Session Initiation Protocol Core Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
