CCM 9.1 dial plan with 11 digits Pros and Con

[dshumake]

all I came into a new setup where they have the following:

DN:  11 digits (1XXXXXXXXXX) which matches the DID's

all LDAP users has +1 dialing in telephone field

I guest this was mainly used for + dialing

used across 5 locations

***

Now they want to add site codes (CCC+last4) 7 digits for internal dialing

                              -- plan on adding 20 more sites.

this would not be so bad if the site had DID's in a con't range.  I am hoping this does not turn into a nightmare

plan:

leave the DN at 11 digits

change the display to show CCC+last4

create translation for the site code (CCC)

                               CCC.XXXX  --  predot, prefix 1678507  =   16785075555

has anyone done this type of dial plan before?  Pros and Con

You got it, you need separate TPs to cover each DID range assuming different area code or exchange, obviously if only the last 4 digits are different you can summarize it even if they are not consecutive as site id is unique and you only prefix area code + exchange.
