I've set up a new extension range in another facility, added the new range to the numbering plan, and built one of the extensions on a phone. Built one of the extensions here, after adding it to the numbering plan, I'm able to call the extension using menu choices, the number can dial out. However, when we try to dial each other across our private T (we're connected for extension dialing and they use our CallPilot), I just get a busy. Is there something I need to change on the configuration of the T?
