LERG Blocking

The Telcordia LERG database tells you many information of a phone number and the important data we get for call blocking purposes are :

  • Country of the Phone Number

  • Operator Type of the Phone Number ( ex. Wireless, Landline, etc )

The selection provided by Class 4 Fusion are as follows:
