This is an unusual question -
For theatrical purposes, I would like to capture the microphone audio from an old telephone set (let's say a touch tone phone from late 80s) and get that as a line output. Don't need to capture the ring, the dial tone or the dialing, just the output of the microphone. In addition, it's not necessary for this rig to sound exactly like an old POTS line (further artifacts and processing will be added in).
I already own a Gentner Hybrid telephone line coupler box which could potentially make my job extremely easy.
While I've seen a number of POTS phone mods, I'd also rather not build anything or adapt the telephone in any way unless absolutely necessary.
Has anyone on this board achieved what I'm trying to do with a Hybrid coupler box?
I've done a little digging on POTS lines but I'm not 100% sure what voltage / current I would need to provide for the phone to operate. Assuming the input to the hybrid is an RJ11 jack and the phone to be connected can be connected to the set connection on the back of the Hybrid, it looks like I just need to provide between 3 and 9 volts DC between the tip (green, -) and ring (red, +) and 20 mA current.
Can anyone please confirm?
Thanks in advance.
