How to enable authentication for INVITE

Hi All,

Does Asterisk have an authentication feature for INVITE message??
As we know, for REGISTER, Asterisk does have.

If Asterisk also has authentication feature for INVITE, then could anyone please tell me how to enable it…

Thank you

Asterisk authenticates INVITES by default. You can disable it from checking authentication by setting the option ‘insecure=invite’ for the sip peer.
