[cisco-voip] Numbering Plan Recommendations

[Jason Aarons (US)]

Working on a 6000 phone deployment, several large campuses across
multiple states, single cluster;

 

Option A) 4 digit within site (each site is its own Partition), between
sites Star+2Digit Site Code+Last 4 Corporate Address Book (existing DID)
(uses Translation Pattern making it more complicated for customer to
understand)(bigger company would use more digits for site code)

 

Option B) 6 Digit everywhere (single cluster); 2 Digit Site code + Last
4 Corporate Address Book (existing DID)

 

 

Problems;

DID blocks containing XX0-OXXX, zeros messes stuff up. It seems the
numbers the telcos have "leftover" are crappy numbers like 904-789-XXXX
or 904-980-XXXX.
