This is for a motel. Currently my phone line provider does not have a permanent caller id block on outgoing calls. However, if I press *67 after pressing 9 it will do it but the draw back is that it has to be done every time a call is made.

Is there way I can program the phone system to automatically dial *67 after pressing 9 and then letting the user dial the regular phone number? My problem is guests will call people who don't answer and then they call back saying "Hey somebody call me?" which is really frustrating when you have 48 rooms and don't know where it came from or really don't care.
