Re: [Sipping] Liaison Statement on offer/answer procedures

[Paul Kyzivat <[e-mail]>]

I agree that sipping is the right place for the work, and that it ought 
to be done, eventually. It hasn't seemed like especially pressing, but 
apparently 3gpp thinks otherwise.

I agree that, at least on the surface, it is less important which 
solution is chosen than it is that *some* solution be chosen. But there 
are pros and cons to the two obvious approaches, so it is best to do 
more than just flip a coin.

	Thanks,
	Paul
