Hi Eric,

I only have two of these but have not come across an echo problem with 
them on SIP at all. Nothing unusual needs to be done to the config at 
all. So although I don't know how to help you, you can be assured that 
the problem is solvable and not down to the actual phones themselves, if 
you see what I mean?
