Any help appreciated on this, I'm trying to find a MOD-SC cable to attach a live-feed to a FXO port. (As specified in Cisco docs)
If the cable doesn't exist can anybody tell me details on how to connect an MP3 player to stream music via an FXO port. i.e. pinouts to RJ11
It does not. There is no polarity in sounds signals (there is phase for stereo systems, but that's another issue).
Since audio files are stereo and have a much wider frequency response than telephone, the best way to send music to a telephone system is to convert audio files to mono, sample rate of 8KH, 8 bits per sample. You need good audio software to do that. You can then wire phone pins to either channel of the audio player.
