We have 50 Grandstream's that we purchased about 3 months ago.
They're all at one site and we've had nothing but trouble with all the
phones. The echo is the worst problem of all. We had to upgrade from
the default 1.0.1.9 <http://1.0.1.9> firmware to the 1.0.1.12
<http://1.0.1.12> "beta" to get the speakerphone to work properly.
Once we did that, there is now a bad echo if one of the GXP users
turns their volume up too high, the other party can hear an echo. If
the GXP user turns their volume down a bit, the echo starts to go
away. This happens internally from GXP to GXP as well as with outside
callers. At first Grandstream didn't want to admit that they knew
about this or that they'd even ever heard of this problem before. But
they finally at least said they would have an engineer check into it.
Then after some research online I come to find that lots of people are
having the echo issue with the newer firmware and they had also
notified Grandstream months ago. So they know about the problem.

Well you could buy Polycoms, except they have the same problem.
Or the Snoms... oh, yeah, they have this too
Or the Sipuras... damn, same problem
It would be interesting to see someone compile a list of phone which
echo cancel the handset properly.
