Michael,

I have never been able to get the Grandstream to register reliably - 
with any version of the firmware. It sounds like in your test with the 
fixed IP, you left the registration option on the phone set to yes. With 
a fixed IP and host=IP address, I am pretty sure that you must turn off 
registration on the phone. It's useless anyway with fixed IP and just 
reduces reliability (as you have discovered the hard way). Asterisk 
periodically sends polling packets to the phone, so it will know when it 
is reachable and when it is not. And, the phone will still authenticate 
against the password, so this should not lower security at all.
