[asterisk-users] Forward loop protection...

[Carlos Chavez]

     Ia had a server overload today because someone did a call forward 
to their own extension.  To do a call forward I write a key called CFWD 
with the extensión number and number to dial .  The main script tests if 
the key/value exists and dials the number stored in the database.  What 
is an easy way to prevent dumb people from creating a loop?
