I recently upgraded all our phones to the latest Polycom firmware
1.6.2 and went from great speakerphone to tons of feedback. I would
hate to have to go back to the old firmware. Although Polycom
recommends keeping the older bootrom unless you need https
provisioning, I'm going to try the new bootrom and see if it fixes the
problem.

This is being experienced across 3 corporate offices with 3 separate
Asterisk servers. And I have to reiterate... all was good until the
firmware upgrade.
