our company's main # is a POTS line that was ported over T1. Along with T1 we got a new range of DIDs, one of which we'd like to use as our published main #. We are still going to keep the other number as well. Right now all my unassigned DIDs go to attendant anyway so technically it works fine now but to prevent anyone from going in and mistakenly taking this one DID and using it for something else what should I do? can i do something as simple as making this one DID a dummy ACD DN to NCFW to current ATDN? Or it this more complicated now that I'm going to use this one DID as my published main #? Thanks for your help.
