Pre-existing blocked locations
International Revenue Sharing Fraud, or IRSF, is a huge problem. Through fishing attacks or bad actors within an organization, fraudsters gain access to a user's login credentials. Once able to sign in the fraudster begins making a high volume of calls to premium international destinations and up to 25% of the cost of the call goes into their pocket!
Due to the high risk of this type of fraud certain international destinations are automatically blocked by AVOXI. Outbound calls cannot be completed to these locations from the AVOXI web or mobile phones.
To identify blocked destinations sign into your AVOXI platform and follow the below steps.
- Select the "Home" section of the lefthand navigation bar.
- Click the "Settings" tab.
- Select the "Block List" section.
Blocked destinations are created based on source number or dial prefix. Source number will block all calls to the number. Dial prefix will block all calls to the any number starting with the prefix.
- Example source number: +14048592703
- Example prefix: +14*
To unblock a destination due to a legitimate business need the rule blocking a location can be deleted in the AVOXI platform.
- Select the "Home" section of the lefthand navigation bar.
- Click the "Settings" tab.
- Select the "Block List" section.
- Click "Delete" on the destination
