Konexx 100 Telephone Recorder

I've used a similar device for years from Dynametric without any problems. But, you can't beat this price at Amazon. The Konexx enables your cassette recorder, PC sound card, any mic jack, etc. to interface with your phone. FYI: All sides of the phone conversation are recorded at equal volume levels. And, this does not require a power source. I usually use Audacity (GNU/Public freeware) for the recordings and then you can save the file in any format you prefer: mp3, ogg, wma, etc. I like Audacity because it's so easy to use - simple to tweak the sound levels during the call as well to compensate for low talkers.

I have an office phone (Avaya 4625SW IP) that I needed to be able to record phone conversations on and this unit works great. I actually have a plantronics headset and "vista" amp, so instead of being connected on the handset, I have it on the headset output. I don't have it connected directly into the soundcard, instead I have a small submixer ( Behringer XENYX 1002FX ) that I use to select multiple input sources into a professional sound card ( RME Hammerfall ). But it should work fine with a regular sound card too.

I have used this for the past several years to record telephone interviews with my computer. The Model 100 is a little more expensive than the standard Radioshcak special, but it works so much better. The conversations are always clear, well as clear as they were durring the phone call. In addition, I record the conversations as MP3 files and then play the back with Winamp, because winamp has nice contols, x, c, and v, for plaing and pausing, so its easy to transcribe. This is worth it, and it hook up between the phone base and the hand set, won't work on speakerphone.
