[Asterisk-Users] Any way to prevent this from happening

[Joseph Rothstein]

Typical user error, one user forwards his calls to another using CFwdAll on
Cisco 7940, but the user receiving the call has done the reverse.

Does anyone know of a way to prevent this from happening by dialplan
manipulation? Also, same thing happens when a user forwards all to him or
herself.
