I'm amazed it got that far with Polycom.  My experience is that they do not
support these phones at all.

What version of * are you using?  I'm using 1.0.2 with Polycom 1.3.4
firmware on IP600's and I haven't seen any of these problems.  If you'd like
the 1.3.4 version of the firmware, just let me know off list.

Stupid Question:  Is the echo on all calls or just on calls to/from the
PSTN?  If just PSTN calls, do you have any echo cancellation enabled?

Thanks,
Noah
