cmrabet Posted October 27, 2010 Report Share Posted October 27, 2010 Hi I have a new problem. I detected someone form outside our network registering in one of our extensions to place calls through one of our trunks (CallWithUS) running out our credit. The CallWithUS call records show calls made from this extension to a crazy list of different countries (that we do not call to). I changed the SIP password for the extensions but this happened again. So far 3 times. What is your recommendation to protect the PBXnSIP server against this? I had also set a Trusted IP Addresses to every extension but this did not make the trick either. Thanks.

So far 3 times. Don't choose trivial passwords! There is a reason that the PBX has a password policy (though it was a marketing decision to disable it by default). Check the following passwords/items: Set the password policy for the domain Set a reasonably safe system admin password Set reasonably safe extensions passwords Set a reasonably safe domain provisioning password Specify an outbound proxy for trunks, and possibly explicitly specify the addresses for inbound traffic.

Just to add to this, may be you can create some dial plans based on who can call where/who etc and assign them accordingly. Quote Link to comment Share on other sites More sharing options...
