Changing codec doesn't appear to matter. I gather that the cause is that 
the GXP-2000 sends empty udp packets as keep-alives. (which is all well 
and good, but even with a handful of handsets with light call volume the 
logs fill up with notices, at the moment there is only 1 call going 
through the server and this is generating 2 notices/second.

Is there any way to make asterisk ignore the empty packets from certain 
peers?
