Both keep card data out of your business and drop you from SAQ D to SAQ A. The difference is what your agent does during card capture. Here's how to pick.
| DTMF Suppression | Channel Separation | |
|---|---|---|
| Audio architecture | Single channel, tones suppressed in real time | Two channels, agent's audio off-line during capture |
| Agent during capture | Stays on the line, can talk customer through | Hears hold music, watches a progress indicator |
| Card data destination | Straight from customer's handset to Paytia | Straight from customer's handset to Paytia |
| What's in the recording | Flat replacement tones, no card data | Hold music on agent leg, no card data |
| Best for | Conversational sales, retention, complex calls | High-compliance environments, hands-off capture |
| PCI scope outcome | SAQ D → SAQ A (329 → 22 controls) | SAQ D → SAQ A (329 → 22 controls) |
| Telephony required | Any modern CCaaS, PBX, or SIP | Any modern CCaaS, PBX, or SIP |
| Time to live | Days to a week | Days to a week |
| Training required | None — one keypress to start | None — one keypress to start |
| Also called | DTMF Masking | — |
Want the long version? How to think about the choice digs into the compliance, customer-trust, and cost trade-offs in detail.
Card data never enters your network, your agents, or your call recording. Both products run on the same PCI DSS Level 1 Paytia platform and connect to the same payment gateways — Stripe, Barclaycard, Worldpay, Adyen, Tyl by NatWest, Ryft, and others.
Both move you from SAQ D (329 controls) to SAQ A (22 controls). Both work with any modern telephony — Genesys, Five9, Amazon Connect, NICE CXone, 8x8, RingCentral, Talkdesk, traditional PBX, and plain SIP trunks. Both go live in days, not weeks.
Switching from one to the other later is a configuration change, not a re-implementation. So if you start with DTMF Suppression and your compliance team later asks for Channel Separation, you're not rebuilding anything.
Two products. They share the same outcome — card data never enters your business — but the underlying audio architecture is different. DTMF Suppression keeps a single audio channel and strips the keypad tones in real time. Channel Separation splits the call into two channels and takes the agent off-line during capture. Both are sold and supported separately, but most customers only need one.
Both deliver the same compliance outcome — SAQ A, no card data on your network, no card data in recordings. Channel Separation gives compliance teams a stronger story for audit because the agent's audio path is physically off-line during capture, but the actual scope reduction is identical.
Yes. Both run on the same Paytia platform with the same gateway integration. Switching is a configuration change, not a re-implementation.
Both work with any modern telephony — Genesys, Five9, Amazon Connect, NICE, 8x8, Talkdesk, RingCentral, 3CX, traditional PBX, and plain SIP. We'll assess your setup before recommending one over the other.
