Hi, 

I have a VoIP gateway configured 1) to register with my proxy, and 2) to
have calls routed to it from my proxy. 

I shut down the gateway to test what happens if the proxy can't find it.
Here's what I found:
If I dial from an IP phone, it sits there waiting for a timeout to
expire. But, traces show the proxy received an ICMP destination
unreachable response. Should the proxy pass this on to the client in the
form of a 408 or 404? 

If I call to an IP phone I disconnected from my LAN, wait for the reg
timer to expire, the calling phone will receive reorder tone. 

Should the gateway and IP phone have the same behavior?
