[Users] logon problem

[Klaus Darilion]

This should be no problem. Use ngrep or tcpdump to sniff all the SIP 
traffic. If a phone loose registration, write down the phone and the time.

Then take a look at the network dump and find the REGISTER transaction 
which failed and analyze. This will give you more insight.
