WE are moving from a Call Pilot system to a DuVoice system. We are currently using a CDN in the Call Pilot, and will be using and ACD in the DuVoice. What is the best way to move/forward the CDN number to the ACD for the DuVoice system? We really don't want to delete the CDN, in case we have to go back to the Call Pilot. Management wants the voicemail number to remain the same. Thanks!
