 Erick, we're also using 1.0.1.12 <http://1.0.1.12>, having some echo
problems, mostly with in/out going ZAP calls (on quadBRI, w/asterisk 1.0.9),
the internal SIP calls seem to work fine. (but you have to make sure your
volume isn't too high) Also the GXP-2000 has the annoying feature that calls
get disturbed when you touch the wire (going from handset to phone).
 We are having some echo issues but that is due to echo cancellation (we
think) on zap calls, I'm now starting a test (by using it for a while) with
a cisco 7912 to see if it makes any difference.
 Please keep me posted, I'll inform you of my experiences..
 Cheers.
