CMAM Directory Listing

I now have the need to have the DID’s I acquire listed in a directory… CNAM And my current DID provider does seem to offer this option (10.00 a DID) and a 2 week wait… Is there a way to list my DID’s myself or go through a DIFFERENT company for the DID Listings via CNAM…

I hope I used the right technical jargon… smile.
