[Asterisk-Users] Dynamic registration to flakey for production system

[Chris Albertson]

I'm debugging SIP registration too.  My next step is to
install an Ethernet "sniffer" to log everything that goes ovr the 
wire using ports 5060 and 8000~8020.  I'll soon know what's up.

You would be able to see if the phones are "forgetting" to register,
or if they are and Astrisk is dropping the data on the floor.

Switched Ethernet means I have to run the sniffer on the server
however or go and find a non-switching hub.
