Managing fraud is an important part of your business. Here are the tools available to help you.Activate International CallingBy default, International calling is disabled on your Reseller account. To have it activated, please send a request to the Control Tower. Once activated, it will be allowed for all the domains within your reseller account (you do not need to make additional requests for each domain).Users with Voicemail PIN numbers 1234 or 123456 after 12/24 will have their dial permission set to US and Canada Only.  This policy is being implemented in our continuing effort against fraud prevention. Restricting International CallsIf international calling has been enabled for your Reseller account, these are the ways that you can restrict international calls at the Domain and User level:Set Domain default dial permission to 'US and Canada'. When a domain is created, you set the domain defaults that will be passed to each new User that you create within the domain. Among these is the default Dial Permission. It is highly recommended that you set this to 'Continental US'. If you wish to enable it for individual users then you can do so in the User's profile.Set User's dial permission to 'US and Canada'. Each User has a profile that contains the dial permissions for that User. It is highly recommended that you set this to 'Continental US' by default, and only allow international calling when specifically needed. Monitoring Telco UsageThe system tracks the value of all PTSN termination calls made by each domain. You can view this usage from the Manage Telco page an widget of the Reseller Dashboard. You will also receive a daily usage summary showing the total PSTN usage for the day, broken down by domain. It is intended that resellers will use this facility to monitor for any unusual activity.Fraud AlertsWe continually look at usage per customer for the past 8 weeks and generate a fraud score for each customer. If the fraud score exceeds a predetermined amount, it will trigger an alert. You will be notified by email of any alerts that trigger for domains within your Reseller account.Here is the content of a sample fraud alert message:EntityCPMASRACDACRARRSCRDCRCPM VarianceASR VarianceACD VarianceACR VarianceARR VarianceSCR VarianceDCR VarianceScoreBarry Communications0.03 [+0]50% [+0]34.95 [+0]0.022901 [+0]0.015450 [+0]100% [+0]100% [+0]-93% [+0]44% [+0]2681% [+0]431462% [+100]23254% [+0]2% [+0]23% [+0]100The metrics that the algorithm monitors are:CPM: Cost per MinuteASR: Avg Seizure rateACD: Avg Call DurationACR: Avg Call RateARR: Avg Route RateSCR: Src Call RateDCR: Dest.
