Hey everyone!

About the cheapest way to generate a ring-voltage problem...

I've seen several "call directors", a box that picks up a ringing line,
listens, determines if it's an incoming fax or modem, then sends the
signal to the corresponding RJ-11 jack where the actual device is
plugged in.

Wouldn't one of these have to generate a ring voltage to get the fax or
modem to go off-hook?

Anyone have a schematic for one of these? It might be a rather simple
thing to modify one of these for the OP's purpose.

Comments?
