I have been extending the phone system into the second building using only a pair from the bunch of twisted pairs for the network, but it seems the old corded phone doesn't ring even though it has dial tone and can dial out. When I plug this box in line with the phone it will ring.
It appears there is only a 470k resistor and a 1.8uF capacitor in it (see pic), I tried making another circuit so I can have two phones in there but it blocks out the dial tone.
I tried a cordless phone without this box connected and that will ring perfectly fine. I don't understand why one phone works and the other doesn't.
Thanks,
Jules
