Cabling Instructions

Summary : Place the CallFinder in a convenient location, and
then connect it to earth ground, to your AC power outlet, to your
Ethernet network, and to your telco DID service. You cannot
connect the CallFinder's Extension Ports (FXS/FXO) to your
PBX until after you have configured the CallFinder software. In
the CallFinder software, you will configure the Extension Ports
as either FXS or FXO, and this must be done before they can be
connected to your PBX.
