How to record only the caller?

[etnies14]

Does anyone know how to record only the incoming signal through the phone line? I recently purchased a decent external voice modem. Before one of my business cell phones could record conversations but it would only record the person on the other line nothing I had said and that would be perfect for the training program we are putting together. Could anyone help me out, it would be greatly appreciated! Also if I am using the wrong program or any other program that could accomplish this. I would like to use recording software and the external voice modem to accomplish this.

If you use Skype and Hotrecorder, you won't need to bother with the voice modem. Then you can edit the track in free Audacity and you'll see the incoming will be on the left track, and the outgoing audio is on the right. You can eliminate one and make the remaining a mono track.

A regular POTS telephone is setup electrically so that your earpiece is coupled via a transformer to the mouthpiece. At least this was the original design when phones were first made. With new elecronic phones I do belive the transformer is still in there in many cases but it's not long before that expensive piece of copper will go away. However I'm 99.9% sure the specification for phones is that the earpiece hears a portion of the speaker's voice. So that will not go away unless you design some special equipment to try to block the outgoing (your) voice.

And it would not be blocking at first glance to my thoughts. It would be more like active cancellation of the outgoing voice at the incoming to your own earpiece. And that's probably beyond your and my capability.

IF you have a regular old fashion phone I do belive that you can by disconnecting some of the wires inside cause the transformer to not couple the microphone to the earpiece. I belive it would require you to hardwire the microphone to the phone line rather than having it go through the transformer. That way your outgoing voice would show up only after
arriving at the other end of the phone line and then being coupled in that
person's transformer (if he has one) your voice might be coupled back to
you but at much lower level. <= this was the reason they used transformers in the first place due to echo of each phone being a microphone and speaker in close proximity to each other. The transformer was there partly to decouple as much as possible the chance of feedback via two phones.

Sorry it's technical and if that's not what you were asking about then I suggest you restate your question in a different way. If that's correct then sorry you can't easily decouple your voice from the caller's voice as far as I know.
