The next generation in secure data handling for VoiP telephony environments

Patented SIP Layer Technology

Introducing SmartSIP™ from IntraNext Systems, the latest security product in our Event Intelligence® Platform. SmartSIP is a patented software application that provides DTMF masking capabilities for contact centers to securely handle sensitive data in attended telephony interactions.

SmartSIP secures sensitive data at the point of entry, confining PCI DSS exposure to the smallest possible footprint.

This application combines Computer Telephony Integration (CTI) and a Session Initiation Protocol (SIP) interface that allows customers to use their touch-tone telephone to enter sensitive information while remaining in constant contact with the contact center agent. With DTMF masking, tones entered by the customer are replaced with flat tones that cannot be converted back to the original data entered by the customer.

Developed specifically for VoIP telephony contact centers, SmartSIP is the only DTMF masking solution that doesn’t alter the voice path.

Descoping a Premise-Based IVR

SmartSIP can also be integrated in front of your existing IVR where customer entered digits are extracted before entering the IVR. The native values are replaced with semaphores (substitute values that meet MOD-10/Luhn validation) to satisfy the IVR collection and validation process. At the point when the IVR script would normally send the payment (or tokenization) transaction to the appropriate system, it is modified to send the transaction to the SmartSIP server instead. SmartSIP replaces the semaphore with the customer’s captured information, and then initiates the transaction on behalf of the IVR. Processor responses are passed back to the IVR and the call flow continues as designed. Since the PAN/SAD was captured and temporarily retained in SmartSIP’s encrypted server memory, the IVR and all downstream/connected systems are removed from PCI scope. The only elements that are in-scope are the Session Border Controller and the SmartSIP server.
