Secure Payment Handling for VoIP Telephony Environments

Eliminating the Verbal Exchange of Sensitive Data

SmartSIP® is a premise-based software application that provides a DTMF suppression and masking solution for contact centers to securely capture sensitive cardholder data in live-operator calls. Customers use their touch-tone telephone to enter sensitive information while staying in contact with the contact center agent. With DTMF suppression and masking, tones entered by the customer are replaced with flat tones that cannot be converted back to the original data. Agent screens are populated with a masked representation of the customers entry. SmartSIP effectively eliminates the verbal exchange of sensitive data between customers and agents allowing for full call recordings and full screen capture.

SmartSIP acts as a SIP proxy between the Session Border Controller (SBC or Media Gateway) and the voice platform, and interacts with the DTMF data while never affecting the voice path. Developed specifically for VoIP telephony contact centers, SmartSIP secures sensitive data at the point of entry, confining PCI DSS exposure to the smallest possible footprint.

  • 1
    Protects telephone-based payments for PCI DSS initiatives
  • 2
    Capable of tokenizing data at the point of capture
  • 3
    Prevents cardholder data from entering the call recording system
