We are in the process of migrating our DID trunks to a sonnet ring. AT&T built us two new PRI's on the ring and took 5 numbers from the old working PRI's for us to test calls. I am trying to figure out how to test these numbers on the new PRI's. I built new trunks, routes and d-channels for these new sonnet ring PRI's. Do i have to build DSC's for these numbers and then put the numbers on a phone? Any help would be greatly appreciated.
