The IESG has received a request from the SIP-TO-XMPP WG (stox) to consider the following document: - 'Interworking between the Session Initiation Protocol (SIP) and the Extensible Messaging and Presence Protocol (XMPP): Architecture, Addresses, and Error Handling' <draft-ietf-stox-core-07.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 2013-12-11. 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 As a foundation for the definition of bidirectional protocol mappings between the Session Initiation Protocol (SIP) and the Extensible Messaging and Presence Protocol (XMPP), this document specifies the architectural assumptions underlying such mappings as well as the mapping of addresses and error conditions. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-stox-core/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-stox-core/ballot/ No IPR declarations have been submitted directly on this I-D.
