How can I make my audio equipment connected to a phone line?

I would like my music CDs to play on my system telephone conference to allow anyone worldwide to dial into the conference, and hear the music I play on my CD. I know that some organizations use a telephone conference bridge or a phone patch, but the boxes cost more than $ 100. Is there another way I do it? I tried to buy a small a plug adapter for 3.5 mm audio one end and an RJ11 port on the other side, but this card will not let me listen to music with the phone in my house alone. I would like be able to play music on my conference system.

How convenient that you are with a soldering pencil? The easiest way to connect a tensioning device (audio amplifier) to a current device (phone system) is the capacitive coupling. The telephone system works by varying the current loop, you can not add something that changes in voltage, and output audio from a CD is the tension …. SO ….. Use two, 47 MFD (which is ITEM FOUR September microfarad) ceramic disc capacitors, isolation transformer 600:600 or 1K: isolation transformer 8ohm …. Council contact C1 side of the phone line. The other side of the C1 goes from one side of the transformer. Connect with the C2 ring on the side of the phone line the other side of C2 goes to the other end of the transformer. C1 / output T ][---------)||(--- -------- --------> ....... ....... ... ...) | | (R -------- ][---------)||(----------> C2 i hate graphic text ! The side of the Enter transformer can MIC or LINE OUT, no matter rally because you're the telephone line interface. The difference is the processor found isolation. If it is 600:600 for this job or leave. If this is 1K: 8, then it could be used to play alone, since that line at the CD is 8 ohms, and the processor is 8 ohms, you receive a maximum power transfer. You can do whatever he wants on the side away from Transformer ... Add a volume control (line level) of a meter, so your trigger travel. This basic circuit network is loaded so it must withdraw from the phone line when not in use. The C1/C2 should be at least 200 volts value the work is not critical, perhaps, 47 -, 1, over the top, the signal is coupled. You can get away without the processor, but requires more circuits. The patch telephone conference bridge, etc, all of which meet the FCC Part 68. My circuit can not be sold as far as I know, she has never met the Part 68 of the rules, because he takes the line ...
