We have a customer who is facing this problem.<br><br>There gateway asterisk to the termination side is being attacked by the hacker.<br><br>The gateway asterisk is using ip based authentication, and also iax user name and password.<br>
<br>The hacker is somehow able to send out the call out via the gateway asterisk, faking the ip address.<br><br>The FULL log does not show any trace of the call or the number which is being called in the NODE Asterisk of which ip is being used, however the log of the GATEWAY Asterisk shows that the call was made from the IP of the NODE asterisk.<br>
<br>Any suggestions, what they can use to do a further authentication for this particular customer ?<br><br>Rehan<br><br><br>
