Re: [dispatch] PROPOSED CHARTER FOR ASAP (Automatic SIP trunking And Peering)

Hi,

Shouldn't the charter also mention why existing feature- and extension indication mechanisms would not work? The way the text is written now one could think that SIP does not providing mechanisms for indicating support of features and extensions...

Regards,

Christer

(still individual)

Oops, I forgot a question: Is discovery in scope? I assume so, from the TBD section in draft-kinamdar-dispatch-sip-auto-peer-01. If so, it’s worth mentioning in the charter.

Thanks!

Ben.

That is, rather than saying sending a “ protocol specification draft” to the IESG, you can talking about sending the “protocol specification”. The work group could later decide to organize that as one or more drafts as they see fit.

I suspect the second, in which case I suggest the statement that “The group will not…” be reformulated along the lines of “The following is out of scope…”

>> All,
>> Following the presentation of SIP Auto Peer at IETF 106, Singapore (https://tools.ietf.org/html/draft-kinamdar-dispatch-sip-auto-peer-01) , there was consensus to form a mini workgroup to take this effort forward. To that end, we are looking to build consensus on a charter. The prosed charter can be found below. Comments, reviews, suggestions are welcome.
