Folks,

there has been substantial discussion on the topic of extensibility
models for SIP. Advancing consensus on this topic as a whole requires
broader discussions. Consequently, we are organizing an ad-hoc meeting
on Monday night between 2200 and 2400. We understand it is a bad time
but it is difficult to find empty meeting slots.

The agenda for this ad-hoc meeting will be as follows:

1) Problem overview and review of the multi-fold path (Extension
messages, extension headers, extension bodies, EVENT/INFO transport
packages, and non-SIP session/transport protocols.

2) Review of the "litmus test" guidelines for choosing an extension
modality, which we expect to eventually lead to a guidelines document.
Discussion to include the the use cases that are addressed by MEDIACTRL
Control Channel, MSRP, MSRP file transfer, and TOTE.

3) Discussion on clarification and finalization of the INFO
packages document. We would not be taking explicit HUMs in this
meeting about consensus as to whether or not to proceed with INFO packages.


We do not still have a meeting room. We will be reporting back to the
SIPPING list as soon as we get one.

Cheers,

Gonzalo
