In the past, on other systems, you had to be careful with the last 3 digits of a DID conflicting with a Numbering Plan.

I service a lot of Norstar DID equipped systems, but am in the midst of a clients ordering process for an upgrade. Adding T1/PRI and DID's.
MICS, 6.1, PRI

I want to be cautious.

Can the Norstar receive 0 & 1 (9 ?) as a first digit of the 3 being sent.
The client bought a bank of 100 DID's ending in 200 but in a new area code....cool.
But they want to convert some 1mb's to DID because of Area Code. (new area code is not popular)
is their an issue with, as example:
213 393 0023 and/or 213 393-9072

I was just set up for 3 digit Dn and receive 3 digit.
My brother said when I see the 023 just send it to the Target Line and put that on the Ext.\
that would be great.....I am just a little antsy.


Any ideas?
