Since I opened my mouth, I would suggest sending a valid CNET number 
that could be returned. Perhaps some even have the ability, or should 
would, do a "return call" so either 1+NXX-XXXX or NXX-XXXX for North 
America.
Sorry my mind STILL can't get around the open numbering plan to offer a 
suggestion there.
Sending the "200" NPA never made much sense to me either. Perhaps I 
can't see where CNET will ever have to go beyond 7 digit dialing for 
North America, and  the current International scheme.

Fairly simple to change the Motorola to use a 7 digit number. I have 
found that the user name and number must match, which seems to be an 
Asterisk limitation. I could be wrong on that, as it has been a couple 
of months since I messed with the VT 1005

Simple enough to have each device report its CLID, or use one CLID that 
reflects a good callback number.
Also would be nice to either send a name or some device identifier. I 
probably need to re examine some of mine as well for that.

That should also work, if the dialplan is programmed correctly.
I allow dialing as either 7 digits, 1 plus seven digits for North 
America, though I never dial it that way myself my portal will accept 
that format

Bet that is Dennis Hock through Greg's switch. I suppose a return call 
could parse that into a good CNET number

Why not simply get rid of the 200 NPA??

CNET expects 1 plus 7 digits for the DNS/ENUM to work properly, but 7 
digit CLID for North America is what I consider ideal.


Just my opinion, though
