Re: [martini] Implications of multiple AOR/contact mapping

New to the list so if I'm missing something, sorry about that.  If I 
understand correctly, the assertion is that with 
draft-roach-martini-gin-00/imlicit reg, the PBX sends a single AoR to the 
SSP which (because of it's provisioning) automatically activates all the 
associated records in it's location database and just replies to the PBX 
with a generic ();bnc to indicate success.

Provisioning aside, I tend to agree that the PBX needs to be informed of 
which numbers the SSP considers to be implicitly registered for that AoR. 
I'd hate to lose functionality by moving to implicit/bulk reg.  For example, 
if I register 100 numbers individually and 10 of them fail, then I stop 
subsequent subscribes/notifies for those numbers and, in the case of some 
PBX's, even present to the end user that their line isn't working.

Provisioning disconnects happen all the time between PBX's and SSP's as a 
result of MACD's.  I'm not proposing MARTINI resolve procedural issues, but 
a lack of two way acknowledgement of which numbers both parties consider 
active is a loss of functionality.

I realize draft-roach-martini-gin-00 suggests a NOTIFY request to 
communicate status.  To me there's a difference between a negative/failed 
registration state vs. relying on a PBX to interrogate the SSP after the 
fact.
