How does your International call fraud protection work?

We attack the problem of international call fraud on a number of fronts. First, we turn off International calling by default for all newly provisioned SIP trunks. You are able to modify this setting in the Control Panel. Second, you have the option to set the type of international calling ability on each trunk on our system (North America-only, or all international). In addition, you are able to set the maximum threshold for a calling destination for each trunk (by default it is $.25 per minute). SIP.US also maintains proprietary real-time International call fraud protection systems that monitor for potentially abusive international dialing patterns. If we suspect your SIP Trunk has been compromised we will automatically terminate calls in progress, disable international calling on your trunk and notify you of the incident.
