J,
You could use translation profiles on the CME-side to address this need. Given that your provider blocks calls where the CLID is outside of a certain range implies they can provide that range to you. It is likely you already know what that range is. From there you can build a translation profile that passes CLIDs that are in the approved range and then change CLIDs that are not.
For example. Assume you have the following:
DID Range (approved by carrier): 7035552000 to 2999
BtN or DID you want to mask for numbers outside of the above range: 7035552000
Abbreviated dialing (internal extensions): 4 Digit (e.g. 2XXX)
CUE can pass 4d or >=10D depending on who called the attendant
The following translation rules and profile can be applied:
voice translation-rule 99
rule 1 /^2...$/ /703555\0/
rule 2 /7035552.../ //
rule 3 /.*/ /7035552000/
voice translation-profile PRESENT-CLID
translate called 99
!
You can apply the translation profile to an existing dial-peer. It is likely you have more than one dial-peer. Just as an example:
dial-peer voice 91020 pots
destination-pattern 9[2-9]..[2-9]......
translation-profile out PRESENT-CLID
port 0/0/0:23
forward-digits 10
!
The translation profile (PRESENT-CLID) is being applied to the pots dial-peer in the outbound direction. The translation profile is evaluating the CLID with translation-rule 99. If the CLID is a 4-digit number in your range, we expand to 10-digits. If the CLID is a 10-digit number in the range, we leave it be. If the CLID is anything else, we change it to 7035552000.
HTH.
