[Asterisk-Users] Asterisk Stopped working!

[Nitesh Divecha]

Hello all,

All my extensions are dead and when you try to dial any extension number on
the LCD it shows "Loop detected".

On the Asterisk I don't see any of my extension register. Whole system was
working fine and now it's dead. I ran "sip debug" and I don't see any
request sent by my Snom phones. 

There is no any problem with network as all the workstations are running
fine.

Please help!
