No offense to bigcat919 - but I would not change the DID to private. I took over a customer where a tech did that on many DID's - the customer wanted several DID's to ring in multiple places, when I changed the DID from Private back to public, it wreaked havoc on a lot of phones. Spent a bit of time sorting through all the DN's and cleaning up programming. It will be easier for you now but could be a problem later on.
