I looked at the manual and it does seem complete although you are right in that it does not address these questions. It's normally assumed with most of these amps that the MOH output is the same program material as the amp is providing to the speakers. If there is no signal on the output I would suspect a problem with the unit. But before you jump to that conclusion have you checked it with a small speaker directly connected to the 8 ohm terminals or with a butt set?

As for the page input, if the phone system page is low you night want to try using the Mic1 input instead and activate priority paging for that input. Wire an XLR plug hot to pin 2, shield to 1&3.
