Re: O/A model


Isn't there a mechanism whereby both UAs get back to an agreed 
state? How can the negotiation process continue properly 
otherwise?

regards,
Salva

SIP O/A model

Isn't there a mechanism whereby both UAs get back to an agreed 
state? How can the negotiation process continue properly 
otherwise?

manyfolks

Hi Gonzalo,

	This is Salva Rey, from Siemens CT in Munich. How are you 
doing?

	I wanted to comment you a couple of things about manyfolks.

	For what I see in manyfolks it seems that two aspects are 
being defined jointly:

	1. QoS capability exchange signalling and interaction with the 
offer/answer model(through methods and headers)	

	2. QoS requirements (in SDP fields)

	Point #1 will be always managed by the UA, but maybe #2 is 
let to the application...

	this has never been mentioned, but are we aware of this?
	will manyfolks provide any support for QoS capability exchange 
signalling in case that the format for media stream descriptor is 
other than sdp, let's say here sdpng or xml?

	my concern is that maybe these two aspects are woven too 
tightly, and later on manyfolks cannot be used if a format different 
to sdp is used.

regards,
Salva
