Set Account Restrictions for Fraud Prevention

To combat the growing amount of fraud in the VoIP industry, Flowroute is excited to announce a new fraud prevention feature: Destination RestrictionDestination Restriction alerts users if there is a surge in calls to a specific destination. 

How fraud prevention works

Flowroute analyzes your outbound call patterns to various destinations and creates an average metric that accounts for call duration and cost. If there is a sudden increase in traffic to a destination, the account is flagged, and in-progress calls become automatically suspended. The user receives a notification via e-mail and can either reauthorize the destination or leave it blocked.

To view your Fraud Control options
  1. Log on to Flowroute Manage
  2. Click Preferences on the left panel, and then select the Fraud Control tab.  The Fraud Control page appears, showing you your current settings and allowing you to set as deep of a level of restrictions on your account as you want. Click on any of the items below to jump to its corresponding section:

Outbound SIP Credentials
The default option is Enabled. Only click on Disable Credentials once you've made sure your IP address is on the "Outbound Allowed IPs" list (one of the tabs under Interconnection), and have read our article on Setting up IP-Based Authentication for Outbound Calls.

Setting up IP-based Authentication and disabling outbound SIP credentials prevents an outsider from using your SIP credentials to place fraudulent outbound calls on your account and helps secure your account against known avenues of compromise.

Maximum Outbound Rate

This feature sets a maximum rate for outbound calls. When a call placed to a destination (usually outside the US) costs more than the value set here, we will deny it. The maximum outbound rate tool prevents you from calling expensive locations and generally prevents an intruder or a compromised system from dialing high-cost areas on your account. To set this up, check out our article on how to Set a Maximum Outbound Rate.

Destination Restriction
By default, your account is protected by a fraud detection system that continually monitors and profiles your common call destinations and call volume. Should your call volume suddenly spike to unexpected or previously undialed locations, this system may block specific destinations that are out of character for your account. If this happens, check the list on this page again. You'll see the destinations that have been blocked by this fraud system and can choose to unblock them.

Destination Whitelist
You can use the second part of our automated system in two ways. If you add destinations to this whitelist, calls to those destinations will be never be auto-blocked by our fraud system. Exempt from our fraud detection system and will never be auto-blocked after a burst of high call volume. Use this to guarantee delivery of calls to the destinations you most commonly call.

An additional feature is a checkbox for "Use Strict Whitelist" -- checking this will altogether disable our automatic fraud detection system, and calls will only be allowed to destinations on the whitelist. For a more detailed description, see Set up a Destination Whitelist.
