[cisco-voip] Speaker buzzing sounds

I always noticed it with Nextels even before Blackberries.  I now have a
Nextel Blackberry and TMobile Blackberry and both cause the problem (also
causes it with TVs) but the Nextel one is much worse.

I'm pretty sure this is interference of some type. It affects my PC speakers
as well even if they are at the lowest volume (short of being turned off).

Crackberries do the most damage and I can hear the hissing almost twice a
minute as the little devils sync with the network. Godforbid the thing
actually goes off - the phone then does a little jig.

Has anyone had reports of speaker buzzing occurring when people are not on
their 7960s?  Usually, we discover a cell phone near the phone but we have
just had a number of reports of this in the last few weeks without this
reason being the culprit.  We did just install ES27 on the Callmanagers
which included phone load 7.2.3 but the users insist that the problem was
happening some amount of time before this.  Anyone else out running 7.2.3 on
their phones?  Any other general suggestions for speaker buzzing?

Thanks, 

Pete
