[Asterisk-Users] GXP-2000

I have a client who has about six of these phones.  Luckily (for me, not 
for them) they were purchased before I came into the picture.

You don't notice any problems when using the speaker-phone, but the 
person on the other end hears echo, and quite a lot of it.

My client uses them exclusively with headsets (in a call center) so the 
quality of the speaker-phone isn't an issue for them.

Do you have multiple phones going down at the same time?  If so, monitor 
them with "qualify=500" in sip.conf to see if they hit that limit.  If 
you see more than one go down within a short period of time, you have 
network problems.  Check the quality of the network switches they have. 

Also I have heard some phones have trouble with broadcast packets (at 
least this has been said about the spa-841 on the wiki).  You should 
strongly consider putting them on a separate vlan to avoid any issues 
like that.  In the future, for phones under $100 then look at the 
spa-841 phones.
