Open Question: How can I output audio through the telephone line from a 1/8 audio jack?
I've made this circuit pictured here: http://www.epanorama.net/circuits/tele2.gif
But when I test it, there is a very loud humming/buzzing noise and I can barely hear the audio I'm playing. Is there anyway to eliminate this noise, or a better circuit for this application?
