Secure phone payments for 3CX
Paytia joins your 3CX phone system as a SIP trunk you import via a pre-built XML profile, so there's no rebuild of your dial plan or PBX config. Agents dial 729 mid-call to start a secure capture, the customer keys their card on their own handset, and card data never touches your staff, your systems, or your call recordings.

- Agents dial 729 to start a secure capture mid-call
- Works with softphones, desk phones and the 3CX mobile apps
- Recordings keep running — no pause-and-resume

- Monthly billing with no setup fees and no contracts
How it works with 3CX
Configure the SIP trunk
Add Paytia as a SIP trunk provider in your 3CX administration console using the pre-built XML profile — no rebuild of your dial plan or PBX config.
Agent on the 3CX call
Your agent is on a live call with the customer using 3CX, exactly as they are today.
Dial 729 for payment
The agent dials 729 to start a Paytia secure capture session, and stays on the line throughout.
Customer enters the card
The customer enters their card details on their own keypad. DTMF masking replaces the tones, so nothing reaches the agent or the recording.
Payment confirmed
The payment processes securely through your gateway and the agent gets a real-time confirmation on screen.

How Paytia works with 3CX
Setup starts in the 3CX management console: you import our pre-built SIP trunk profile and your agents are ready to take payments from the phones they already use. When a payment comes up, the agent dials 729 and watches the live status — card BIN, masked PAN, authorization result — in a Paytia browser tab. Here's the flow.

Why teams choose 3CX with Paytia
Pre-built SIP trunk profile
We provide a SIP trunk XML profile that imports straight into the 3CX management console, so setup takes minutes rather than a PBX project.
No hardware needed
Works with your existing 3CX estate — softphones, desk phones and mobile apps — with no extra hardware or app installs for agents.
Recordings stay clean
DTMF tones are masked before they reach 3CX, so you keep continuous recording running for QA and dispute handling without pausing around payments.
Cloud and on-premise both supported
Whether your 3CX is hosted by 3CX, running on your own server, or in a private cloud, the SIP trunk profile is identical — and Paytia doesn't need inbound access to your server.
Payment types and card rules
Assign agents the payment types they're authorized to use — immediate capture, card capture to file, subscription plans, or reserving money — and block card brands or credit-vs-debit use while the customer is still on the call.
Reseller-friendly
We work with 3CX resellers who bundle secure phone payments alongside the PBX they're deploying. Each end customer gets their own Paytia account and SIP trunk, billed monthly.
3CX + Paytia — common questions
How does Paytia plug into a 3CX phone system?+
Paytia sits beside 3CX as a SIP trunk you import via a pre-built XML profile, so there's no rebuild of your dial plan or PBX config. Once it's in, agents trigger a secure capture session by dialling 729 mid-call and the customer keys their card on their own handset.
Will 3CX call recording still work without breaking PCI rules?+
Yes. The keypad tones the customer enters are masked before they reach 3CX, so your call recording captures the conversation but never the card number. That means you can keep continuous recording running for QA and dispute handling without having to pause-and-resume around payments.
Does this work for self-hosted 3CX as well as cloud-hosted?+
It works the same way across all 3CX deployment types — hosted by 3CX, on your own server, or in a private cloud. The SIP trunk profile is identical and Paytia doesn't need any inbound access to your 3CX server.
What changes for the agent inside their 3CX desktop client?+
Almost nothing. The agent stays in the 3CX softphone or desk phone they already use, dials 729 to start the capture, and watches a Paytia browser tab for live status — card BIN, masked PAN, authorization result. They never leave the call and never type card details into 3CX.
Can we set up different types of payments?+
Yes, agents can be assigned payment types they are authorized to use. A simple dropdown menu choice swaps between payment types including immediate capture, card capture to file, Stripe subscription plans, or reserving money on customer cards.
Can 3CX resellers offer Paytia to their own customers?+
Yes. We work with 3CX resellers who want to bundle secure phone payments alongside the PBX they're already deploying. Each end customer gets their own Paytia account and SIP trunk, billed monthly with no setup fees or contract — so resellers can land it on a per-site basis without committing the customer to anything long-term.
