The IESG has received a request from the Session Initiation Protocol Core WG (sipcore) to consider the following document: - 'ISUP Cause Location Parameter for the SIP Reason Header Field' <draft-ietf-sipcore-reason-q850-loc-05.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2019-02-13. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The SIP Reason header field is defined for carrying ISDN User Part (ISUP) 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 network to correctly interpret the reason of release. This document will update [RFC3326]. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-sipcore-reason-q850-loc/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-sipcore-reason-q850-loc/ballot/ No IPR declarations have been submitted directly on this I-D.
