I have a really old AT&T paging system that we ant to page to with our Call Manager 6.12 system. If I hook it to anport on an ATA I just get dialtone on the overhead paging. If I hook to an FXO port I see the number hit the port with a debug voice dialpeer inout but get a busy signal. This is just with default settings on both port types. Any configuration examples or help out there?
