Hi, I have the same issue, looking for a simple way to connect an unused line button (locking screw removed) from a key set to a PagePac Amplicenter.
I came across this Valcom product and was wondering if this would work (I found others, but they required you to dial # or an unused intercom number to connect to amplifier). PAGEPAL® V-5335700 (
https://www.pagepac.com/pdfs/pagepal.pdf) .
The installation guide says "(SA) Station Access Used with a standard (ANALOG) station port on a CENTREX, PBX, Key System or Central Office subscriber line. Use a two-wire RJ11 cable in this mode. The PagePal receives talk battery and ring voltage from the host system". Thought I could connect to the manual intercom card. Any thoughts if this will work?
I just found some on Amazon and another vendor, around $525.00 - seems pricey!
