Hi Henry, Well said. I'm glad we agree. Only one thing, you replied directly to me instead of the list. :-) So I guess you're preaching to the converted. It's at _least_ two cents worth, so post it to the list for everyone.

I had to construct a relay that would activate when a (paging)line was selected. This relay would then switch the input of the Paging Amp from the piped elevator music to the page.

The result will overload the input of the Amp and cause gross distortion. In the end you are much better off supplying an ATA extension and getting a reputable company to set up the paging system. > > Was that more that two cents worth ? > Sorry > > Henry > > > < Dave Donovan> > > > If they don't already have a PA system as Alex suggests, then there are > > companies that do paging.

Simplest way, just put in an FXO board and give it extension 5123. Whenever someone dials 5123, they'll hear the chime and they can just say "Keith, line 1, it's your wife and she sounds upset!" > > > > The one time I dealt with paging was in a warehouse.
