I have several phones running off an Option 11 that are routed to local CO exchange for outgoing calls. (NCOS 0) How do I program a "backup route" so if all the local lines are in use that they will go to our T1 (NCOS 6)? (Option 11c in office in the suburbs with a T1 tie to a option 81C located downtown)
