asterisk users - Jun 2005 - Cisco 7960 mic generating noise on other end

Hi,

I'm having a problem with one of our 7960.  They all run latest 7.4
SIP firmware.

The problem appears on the other end.  The other end constantly hears
a 'crackling' noise.  I have tested using phone set, headset and
speaker and the noise appears on all cases.  I have other 7960 setup
exactly same way (using same asterisk, firmware, etc) so it looks like
a hardware issue.

I'd appreciate if anyone has any insight on this or any other similar
issues before I open the thing.

Thanks!

Lex

And what you gonna do when you do open it up? Look around for the
little dwarf with the hammer?

Its static, 7960s dont like static, they start crackling at first and
if you push your luck enough they discharge on your ear drum.

Get your carpets washed and use static guards on it.
