Can a fraudster beat your system by using a VOIP or prepaid mobile phone?

TeleSign's PhoneID service allows website operators to identify VOIP and Pre-Paid mobile numbers. By using PhoneID in conjunction with Telephone Verification, it's easy to prevent users from entering anonymous VOIP and Pre-Paid mobile numbers, so scammers won't be able to hide behind these phone numbers.
