[cisco-voip] Use an FXO port for outbound calling only - no answering of incoming calls

I believe so long as you keep the phone number that is associated with that CO trunk, nobody should be calling it in the first place except by chance. If you want to dedicate it for outbound calling and want it to give a busy signal when someone calls it, just PLAR it to an non-existent number within that box. A called FXO port will automatically ring and give you dialtone with nothing configured as it's supposed to.

Hi all –
 
I’d like to use an FXO port for outbound calling only – 
I don’t want the port to go offhook    _at all_  for any incoming call/ring event- 
there is other POTS equipment on the same copper pair that should answer any inbound calls.
 
Currently, I have no dial-peers at all in it-  but it’s still answering calls even with nothing configured on it.
 
I can shutdown the ports obviously, but that’s rather counterproductive to using them for outbound calling  ;-)
 
thanks, Tim
