[comp.dcom.telecom] Need Advice on Background Noise Problem

I need some advice with a small phone problem here. I am working in a
noisy lab area where it is sometimes very hard to talk on the phone.
The set is of the 2500 flavor, and the problem is that the mic is
picking up the noise such that the incoming voices are covered and the
remote parties are also getting excessive noise, making it hard for
them to hear as well.

I remember that there used to be noise canceling mics that would fit
on a 500/2500 handset. So, I looked through my ATT equipment catalog
and found this item called a 'Very High Noise Confidencer', #31050-12
@ $37. There are no details as to what handsets this will connect to
or how it even works. Is it a replacement mic element or an electronic
box that inserts in the handset cord or something else?  There was no
picture as it was listed next to the handsets under accessories.

Anyone have further info on this other similar items? Anyone have
additional ideas that might help?  Note that an amplifier handset
probably wouldn't do much but amplify the noise and make things worse,
since the local noise is obviously getting into the voice circuit and
interfering with things at both ends.
