I have an external conversion set up in Conventional Networking to send calls to an external cell phone. If I dial the number in the conversion table from an internal extension, the call goes out as programmed. However, if I take the appropriate number from 28.01 and enter it as the conversion number in 25.02 for one of my DNIS numbers, it rings to the attendant station rather than being forwarded out. Is there some other programming that I need to do in order to get this to work, or is it just not possible?
