Disabling OPTIONS Requests to Asterisk server

I want to know that is it possible to block the incoming OPTIONS requests to the Asterisk server from the SIP clients/users.


If you wan to block a particular type of packet before it hits Asterisk, try iptables using the string module capability. You could drop packets where the string’s like “OPTIONS” that are destined for port 5060 and that’d probably take care of it.
