Do you have any problems when there are a low number of concurrent calls?
Do you ever get any messages saying the phones are unreachable?  Or lagged?
What kind of Internet connection do you have?
Do you have any problems with calls between phones on the same network 
(no routers in between)?
What model of switches do you have?
What model of Internet router do you have?
