System is a CICS 6.1, I have a AUX ringer unit on the internal ATA Ext 237. Works great, at night the receptionist call FWD the main phone to ext 237 it then rings out in the yard. Problem is that if they are in the office they say they can not hear the ringing over the outside horns. I put a answer DN for 237 on one of the office phones. (Not the reception phone) But no ring on phone. Should this set up work.
