"Because I'm checking the From part," "Authenticating" against the From header is insecure. You could authenticate calls from the asterisk box with the auth module then the problem would arise.

When the Asterisk box register to SER it will have this URI sip:s@10.10.10.10, instead of sip:1001@10.10.10.10. Anyone has encountered this problem? Because I'm checking the From part, and "s" is not a valid extension number so it will deny it calling to the gateway.
