Hello All
I'm looking at revising the dial plan on our CUCM cluster. We've experienced considerable growth, and the 4 internal digit dial plan that's currently deployed is no longer scalable.
I'm looking at converting to a E164 based plan and forcing OnNet routing, but running into a problem with noncontinuous DIDs. At many (but not all) of our sites, users have DIDs but our Telco handed out numbers adhoc, and not in continuous blocks. So my organization may own, for example:
+1-700-555-1234 and +1-700-555-1236 but not +1-700-555-1235.
All the ways I've thought about setting this up are messy and really unworkable
As anyone else had a similar problem, and been able to overcome it? Or am I better looking at another way to build my dial plan.

I thought about doing the same thing for my company.
We are in the same boat as you.
Unfortuantely we have to translate everything that comes in from our CUBE to a 4 digit internal extension and they DID's are all over the place.
I basically had to create a CSS for each location and add 3 partitions to that CSS.
Our GlobalPhones-P partition houses all of our internal DN's.
Regular MASKED-P
RP: 9.1XXXXXXXXXX would translate to the sites external BTN
RP: 9.XXXXXXXXXX would translate to the sites external BTN
RP: 9.XXXXXXX is blocked to force 10 digit dialing (Since SIP does not like to play nice with 7 digit dialing
EMERGENCY-P
RP: 9.911 would translate to the sites external BTN
RP: 911 would translate to the sites external BTN
Then These 2 partitions along with GLOBALPHONES-P exist in the sites CSS
So there really is no clean way of doing a nice internal dial-plan.

I might be missing some of the complexity you are describing but if you have for example:
+1-700-555-1234 and you currently have 1234 as the line extension. why dont you make the line's extensions +1-700-555-1234 and make sure your CUBE/Voice gateway translates the incoming called number to full E164. the point it to your CUCM.
