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