Hello,

I need to record both sides of some of my cellular phone
conversations, using my Siemens S46 GSM phone. I also have a 2.5mm
headset adapter for this phone.

I tried using a Diasonic digital recorder with its included cell
headset/adapter, but the recordings were full of hum and buzz. I also
purchased
a specialized black-box recording adapter from Radio Shack, but this
had the same problem.

I later was told that this happens with all GSM phones when you try to
use the audio output directly for recording, that there is something
inherent in the hardware or software that produces an interfering hum
and buzz.

Does anyone know about this, and why there is this problem? And does
anyone know how to get a decent recording from the GSM phone?

Thank you.
