[cisco-voip] 10-Digit Everywhere Numbering Plan Recommendations

[Howard, Chad]

Yep, you've got it in your example.  We're going with a similar plan.
We are including the country code as well for international use.  
 
Keep in mind that the translations are always urgent match - I'm sure
you know that, I just need to remind myself of that when working through
all the ideas and options :).  
 
With your 34xx example, it already overlaps with Virgin Islands, Cayman
Islands, California and New York area codes (if you were going to dial
those DN's without using a shortcut translation).  Maybe you don't have
offices there, just something to keep in mind for growth.
 
You could restrict dialing the DN directly and rely on the various
shortcuts as an option, or use a star to begin those shortcuts and maybe
# for PSTN access.
 
Just some thoughts.  Good luck.

We are implementing IPCC Enterprise and they want Agents to be at any
site.

 

You say Single Partition, 10-digits everywhere with translation patterns
and line text labels making it look like 4-digit locals and
8+SiteCode+4Digits across sites?

 

What do the translation patterns look like to get 4-digit local call to
10-digit DN?

 

My Phone is 404-391-3486, Text Label is 3486.

Dial 3486 then Translation pattern matches 34XX and pre-pends 404391 to
dialed number?

 

I think I like this idea -jason

if you ever plan to use CTI you must have unique numbers everywhere.
your voicemial system will also need unique numbers.
best to go 10 digits everywhere, then setup translation patterns and
line text labels so users can use/recognize 4,5, or 6 digit dialing, but
in the backend everything works based on 10 digit numbers.

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.
