Hi, I have 2 PRI on my IP office 3.2. I want to force all outbound call to use the cheap E1, but if for any reasons, there is no line available, I want that IP office use the other E1... I have found the "line ID", that works, so I can assign the line ID of my cheap PRI to the shortcodes "dial". But if I unplugged the Cheap pri, It doesnt try to dial out via the working PRI. any suggestions?
