Hi,
I work at a radio station, and I'm trying to integrate an incoming phone line into our mixer board. We have IP phones, so a converter box wouldn't help. Thus I ripped open one of our phones and hope to replace the original 45 ohm speakerphone speaker with a resistor of some value and an 1/4" TS jack:
Being completely clueless with electrical circuits, I have no idea how to go about wiring this besides the obvious of soldering the jack to where the speaker was with a resistor in line somewhere. I also don't know how to find out the line level of analog audio connections. I only know that this is theoretically possible.
Some pointers as to what would be good reading? I've read a good deal of electronics textbooks but I don't know where to go from there. Sorry about the absolute noobness here.
