I am having a few problems getting a courtesy phone set up. Here is the behavior I want: 1. The phone cannot make outgoing calls (local, international, etc) 2. The phone can call internal extensions (all are 3 digits) 3. The phone cannot call 911 4. External calls cannot call this phone. They will be redirected to the digital receptionist instead. 5. Internal extensions can call this phone. I've been able to disable external calls and the phone can call internal extensions (points 1 and 2). I think I have also disabled emergency calling, but obviously can't test that (point 3). As for points 4 and 5, I have been able to redirect external calls to the digital receptionist successfully, but am having issues allowing internal extension to call the phone. I had this feature working a couple weeks back, but it isn't working now (I've been doing a lot of work in 3cx, so I can't remember everything I've changed). Right now, I have it setup in the Forwarding Rule Extensions that caller ids for any of the internal extensions will redirect to a ring group which only includes the courtesy phone extension and all others will be redirected to the digital receptionist.I thought this is how I had it set up previously, but now I'm not so sure... Does anyone have any suggestions on how to implement this feature?
