Re: [Ecrit] IETF ECRIT Design Team on Premature Call Termination

["Brian Rosen" <[e-mail]>]

No, actually, it's pretty precise.  It's "premature" unless the PSAP says
otherwise (that is, if the caller attempts to disconnect before the PSAP
does, then it's a premature disconnect).

This sounds a bit like a subjective thing, verses a quantifiable 
definitive thing.

How exactly does a UAC know when it has achieved this status (i.e., 
provided enough information)?

I assume the goal is to have something in signaling that communicates 
this to the UAC, right?

Or is this merely at the discretion of the called party (i.e., the 
call taker's personal satisfaction)?

Where I'm going with this is that I'm beginning to wonder if, then 
how a signaling protocol document should address this, or should this 
not be dealt with in signaling (which is nearly 100% of what we are 
defining -- only!) IMO...
