asterisk users - Oct 2007 - Limit number of times a call can be forwarded

We have had a few different times when a user has forwarded their phone
to himself. This has overloaded the communications to our operator panel
(FOP). One user should not be able to effect the whole phone system! 

Is there a way that the number of times that a call can be forwarded
could be limited like to 10 or even 100? Then even if a user does
something stupid like forwarding their calls to himself, it wouldn't
cause problems for others.

In sip.conf (assuming you are using SIP) you can set call-limit=10. This 
would limit the amount of calls the SIP account can place to 10. Another 
thing you can is have a macro compare the CID of the phone to where the call 
is going to. If they are the same dump the call and maybe have an agi that 
emails the sysadmin and or user of the issue.
