Taking out Buzz from Audio file

I would be surprised if this problem hasn't already been addressed in this forum, but I recorded a phone conversation and I am trying to take the buzz out that came through on the recording. It is not static but an electronic-type buzz.
I was recording from a non-professional analog-to-digital phone recording device straight into the mic input of my laptop, no ISDN line, just a regular phone line.
Anyway, I have tried to use the built-in Noise reduction features of Audition, however, I may not be using it correctly. I am not sure what all of the settings do, but I have played with all of them unsuccessfully. I do know how to capture a noise profile, though.
Basically, if I go to far, the voices begin to sound like they are being routed through a reverb pedal in a large warehouse with echo, and if I don't take the reduction high enough, the buzz doesn't disappear.
I haven't played with chopping off any highs or lows yet, because the buzz sounds kind of mid-range.

When you capture the noise do you highlight just the noise then capture? If you did do it this way try taking small amounts out ... Remember if the noise lands within the frequency of the voice you can only take so much before you start getting the reverb sound you described ... Try working in spectral mode also it might be easier to see where the noise is ... If you like you can E-mail me a minute or so and I will see if I can head you in the right direction ...

I'm having the same problem except it is industrial AC noise that I'm trying to remove from the track. I've tried the Noise Reduction function in Spectral Mode with similar results ... the more I try to remove the noise from the voice range, the tinnier the voice sounds. The Graphic Equilizer didn't seem to make much difference. Would appreciate any suggestions.

Are you captruing, JUST THE NOISE first? Highlight an area that has only noise and then hit OK, now reopen the noise reduction window making sure your whole clip is hightlighted ... In PREVIEW mode, try taking about 60% or smaller out depending upon what it does to the vocal track ... Worst case E-mail me a minute or so sample and I will see what is up ...
