I've noticed that my SPA-2000 has very bad echoing at the start of calls 
going over the X100P to/from the PSTN.  However, within 60 seconds, the 
echo will eventually completely eliminate itself.  The echo is only 
heard from the SPA end, the remote caller does not hear any echo.

Currently I only have two X100Ps and the SPA-2000, so there isn't much 
to test with, but those are my out-of-the-box results.  I have yet to 
tweak any settings to see if I can eliminate the echo problem altogether.

I do have both asterisk's echo cancellation and the SPA's echo 
cancellation enabled.
