I just set up a Merlin Classic 410 system I picked up cheap. I am using it for my home/office as my basic phone system. I have it hooked up with 6 ten-button voice terminals. I have found all the system documentation online and I performed the system reset per the instructions. The only thing that does not seem to work is the ring when calling on intercom. I lift the receiver, hit intercom and my two-digit number for the station I am calling, I hear the two beeps, but the station I am calling won't ring and the speaker is inactive. The light next to the intercom and speaker button lights/flashes on the called unit, but no ring and no speaker. If the called station picks up the receiver, the speaker light goes out and the handset works fine for the intercom call. If the called station hits speaker after now using the handset the speaker kicks in and the calling station can be heard through the speaker. Any ideas why the called station wont ring? Thank you for all your help,
Jim B
