[Asterisk-Users] Grandstream GXP-2000 Poor sound Quality

[Jesus Mogollon]

Greetings

We have all those problems and then some... after a while, the phone starts 
degrading: The ringing becomes lower and lower and there is a lot of 
stuttering in the conversation. Also, if I stop/start asterisk, half of the 
phones reconnect while the rest don't. I was using the same firmare as you 
but had to roll back to 1.0.1.9 <http://1.0.1.9> because of the degrading 
issue. We have some polycoms connecting to the same server and they have no 
problems whatsoever so we know it's a problem with the GXP.

These phones are definately NOT ready for prime time. I would stay away from 
them. Play it safe and use Polycoms or, if too expensive, maybe Sipuras 841. 
These GXP-2000s are pure evil.
