If any other Techs have worked on these systems, I am trying to get loud speaker paging to work with the system. The extensions will not pickup, so I can not connect to the Telephone Speaker. I have tried to set it up as a door speaker, but it needs a signal from the door post to activate it. I am thinking I can connect an answering machine to it, remove the tape, and connect to the speaker on it. Any assistance is welcomed.
