How can I make a COT trunk that is ringing into the system to receive a busy signal if the target DN is busy? Is there any way to do this? the users have this line coming in on a loop start trunk port but they are always using the PRI for outgoing and when they are making outgoing calls the caller only recieves ringback instead of a busy signal. The incoming callers are getting frustrated. any ideas?
