OPS-DIR, Authors,

I have reviewed draft-ietf-stox-chat-10,
as part of Last Call reviews provided by OPS-Dir.

The memo seems ready to publish, as it is one in a series
of memos intended to provide gateway functionality between
XMPP and SIP protocols. The Core spec for this interworking
has already been approved:


https://tools.ietf.org/html/rfc7247


as has interworking for presence:


http://tools.ietf.org/html/rfc7248



This memo covers chat interworking between XMPP and SIP-based
Message Session Relay Protocol (MSRP) [RFC4975].

In my mostly un-washed opinion (limited SIP background,
zero XMPP), the interworking aspects appear clearly described 
and ready to publish.

In an OPS-DIR review, we must ask about manageability.
The approved presence and chat interworking functions require
gateways. However, there don't appear to be any drafts in-progress
or mention of management of the gateway functions in the RFCs.

Perhaps the -stox-chat authors or others would care to comment
on XMPP-SIP gateway manageability, and where that might be covered.

thanks and regards,
Al
