[cisco-voip] Unused Area Codes

[Andrew Dignan]

I am working on an install where 10 digit dialing is being utilized.  I
would like to use an unused area code for my NON-DID phones.  I want to
obviously be careful to not choose an area code that will eventually be
used.  In looking at the NANP database any numbers like 666, 555, 777, etc
are not in use and are classified as "easily distinguisable".  Anway, just
curious if anyone sees an issue with me using area code 777 for my non-did
phones.

TIA,

Andy
