This demonstration shows how Paytia's DTMF suppression technology works during a live telephone payment. When a customer enters their card number using the phone keypad, the DTMF tones are masked in real-time so the agent cannot hear or identify individual digits. The agent sees payment progress on screen while the actual card data remains invisible.
DTMF Masking (also known as DTMF suppression) is a critical security technology that masks dual-tone multi-frequency (DTMF) keypad tones during phone payment processing, ensuring PCI DSS compliance while maintaining excellent customer service. This advanced audio processing solution prevents agents from hearing sensitive card data while enabling them to guide customers through secure payment processes, reducing compliance scope by up to 80% and eliminating the need for complex security infrastructure.
DTMF Masking processes the call audio in real time, detects the keypad tones as they're sent, and masks them before they reach the agent or your recording system. It works with most contact centre platforms — Avaya, Cisco Webex, Genesys Cloud, Amazon Connect and Five9 are the common ones — via standard APIs and webhooks. Card data is tokenised on capture and encrypted in transit and at rest using AES-256. The platform is PCI DSS Level 1 certified.
How long deployment takes depends on your telephony setup. A standard SIP trunk integration is usually a few days' work; more involved rollouts with custom CRM hooks, agent training, or multi-site testing take longer. We scope the timeline with you up front rather than pretending every deployment fits the same template.
DTMF masking is a security technology that masks dual-tone multi-frequency (DTMF) keypad tones during phone payment processing, preventing agents from hearing sensitive card data while maintaining natural customer service interactions. This ensures PCI DSS compliance by eliminating agent exposure to cardholder data.
DTMF masking ensures PCI compliance by preventing agents from hearing or processing sensitive cardholder data during phone transactions. By masking keypad tones in real-time, the technology eliminates agent exposure to card data, typically moving you from SAQ D (329 requirements) to SAQ A (22 requirements) and enabling Level 1 PCI DSS compliance.
Yes, agents can fully assist customers with payment processes while DTMF masking is active. The technology only masks the audio tones of keypad entries, allowing agents to guide customers through payment steps, answer questions, and provide support without compromising security.
DTMF masking works with the main contact centre platforms — Avaya, Cisco Webex, Genesys Cloud, Amazon Connect, Five9 and Microsoft Teams — via standard APIs and webhooks.
Traditional PCI compliance for contact centres is expensive because SAQ D covers 329 requirements across network segmentation, vulnerability scanning, secure rooms, access controls, and ongoing evidence work. DTMF masking moves most of that out of scope by keeping card data entirely out of your environment, so you qualify for SAQ A (22 requirements) instead.
