Document: draft-ietf-sipcore-6665-clarification-00 Reviewer: Tom Taylor Review Date: 17 June 2015 IETF LC End Date: 17 June 2015 IESG Telechat date: 25 June 2015 Summary: This is a very short document expanding on a sentence in RFC 6665 to make clear the requirements surrounding use of GRUUs in the SIP event framework. It is probably good to go except for a minor issue of terminology that needs clarification. The reviewer apologizes for not being current on that terminology if it is a matter of common usage. Major issues: None. Minor issues: The term "local target" is used in the text (and in RFC 6665. RFC 3261 speaks of a remote target, but not a local one. In which document is "local target" defined? Nits/editorial comments: None.
