Overview
This template is for reviewing PCI DSS scope in telephone payment environments where agents take card payments by voice, softphone, or call center workflow. It walks through the full path of a payment call: the business units and locations in scope, the agent desktops used to handle the call, the telephony and recording tools that may capture cardholder data, and the downstream systems and integrations that receive or store payment-related information.
Use it when you need to confirm what is in scope before an assessment, after a telephony change, when call recording settings are updated, or when a new team starts taking payments by phone. It helps you document the payment flow, identify the PCI scope owner, and record open deficiencies with remediation ownership and due dates.
Do not use it as a generic IT audit checklist. If the environment does not process spoken card payments, or if the review is about e-commerce, point-of-sale, or kiosk payments, a different scope template is a better fit. It is also not a substitute for a formal PCI DSS assessment. The goal here is to make the payment-call boundary visible, catch hidden data paths, and leave the reviewer with a clear record of what is in scope and what still needs action.
Standards & compliance context
- This template supports PCI DSS scoping by documenting where cardholder data is collected, transmitted, recorded, or stored in telephone payment workflows.
- The telephony and endpoint sections help validate control expectations commonly reviewed under PCI DSS and related security program requirements for access control, segmentation, and data retention.
- If call recording or agent handling creates ambiguity about scope, a Qualified Security Assessor should confirm the boundary before the environment is treated as out of scope.
- For organizations with broader security programs, the review can also support ISO 9001-style non-conformance tracking and internal control evidence, but it is not a substitute for formal PCI validation.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.
What's inside this template
Inspection Scope and Environment
This section defines the boundary of the review so the rest of the inspection is tied to the correct payment channels, locations, and scope owner.
-
Review scope documented for all telephone payment channels
Confirm the inspection explicitly covers inbound, outbound, transferred, and callback payment calls where card data may be spoken.
-
Business units and locations included in scope identified
List the departments, sites, queues, and remote work locations where agents handle spoken card payments.
-
Current payment flow diagram available and reviewed
Verify a current data flow diagram exists showing where cardholder data enters, traverses, is paused, is recorded, or exits the environment.
-
PCI scope owner identified
Record the person or role responsible for maintaining telephone payment scope and coordinating remediation.
Agent Workstations and User Access
This section checks whether the devices used for payment calls are controlled tightly enough to prevent unauthorized access or local data exposure.
-
Agent desktops used for payment calls are identified and inventoried
Confirm each workstation used during payment calls is listed with asset ID, location, and assigned user group.
-
Payment-call workstations are restricted to authorized users
Verify access to in-scope desktops is limited to approved agents and support personnel with a business need.
-
Screen lock and session timeout configured on agent devices
Confirm workstations lock after inactivity and require re-authentication before access is restored.
-
No local storage of cardholder data on agent endpoints
Verify agents are not storing card numbers, CVV, or related payment data in notes, files, screenshots, clipboard tools, or browser caches.
Telephony, Headsets, and Call Recording
This section matters because the telephony stack is often where card data is captured, recorded, or accidentally retained.
-
Headsets and softphone endpoints used for payment calls identified
Confirm the specific headsets, softphones, desk phones, and related endpoints used during card payment calls are documented.
-
Call recording captures are paused or masked during card entry
Verify the recording solution prevents storage of spoken card data through pause/resume, masking, DTMF suppression, or equivalent approved control.
-
Recording retention and access controls documented
Confirm retention periods, access permissions, and review controls for recordings that may contain cardholder data are documented and enforced.
-
Telephony network segmentation reviewed
Verify the voice environment is segmented from non-in-scope networks where required and that any shared services are documented with data flow impact.
Systems, Integrations, and Data Flows
This section maps every system that touches payment-call data so hidden storage, transmission, or third-party access does not get missed.
-
All systems touching payment-call data identified
List CRM, ticketing, IVR, payment gateway, recording, analytics, remote support, and workforce tools that may interact with card data or payment metadata.
-
Cardholder data flow path documented end to end
Describe where card data originates, where it is spoken, whether it is transcribed, where it is transmitted, and where it is stored or discarded.
-
No unnecessary systems receive cardholder data
Verify only approved systems are in the payment path and that logging, transcription, screen capture, and support tools do not receive card data unless explicitly required and controlled.
-
Third-party processors and service providers identified
Record any external vendors, hosted services, or telecom providers that may be in PCI scope due to their role in the payment call flow.
Controls, Exceptions, and Closeout
This section turns findings into action by assigning remediation, escalating unclear scope, and capturing formal sign-off.
-
Open deficiencies or non-conformances documented
Record any gaps found during the review, including missing segmentation, uncontrolled recordings, or unidentified in-scope assets.
-
Remediation owner and due date assigned for each finding
Confirm each deficiency has an accountable owner, target completion date, and follow-up plan.
-
Qualified Security Assessor consultation required if scope is unclear
Confirm whether the organization will consult a Qualified Security Assessor or equivalent PCI specialist for ambiguous scope boundaries or control design questions.
-
Inspector sign-off completed
Inspector confirms the review was completed based on observed evidence and available documentation.
How to use this template
- 1. Start by listing every telephone payment channel, business unit, and location that handles spoken card payments, then attach the current payment flow diagram to the review.
- 2. Identify the PCI scope owner and the people responsible for agent devices, telephony, call recording, and downstream systems so each section has a clear reviewer.
- 3. Walk through agent workstations, telephony endpoints, and recording controls in the order a payment call is handled, recording only observable conditions and evidence.
- 4. Trace the cardholder data path end to end and mark any system, integration, or service provider that receives, stores, transmits, or can access payment-call data.
- 5. Document every deficiency or non-conformance with a remediation owner and due date, then escalate unclear scope questions to a Qualified Security Assessor before closeout.
Best practices
- Use the live payment flow, not a policy diagram, when deciding what is in scope.
- Verify that call recording pause or masking controls are tested with an actual payment call, not just enabled in configuration.
- Check whether shared desktops, hot-desking, or remote agent setups create unintended access to cardholder data.
- Confirm that no local files, browser caches, downloads, or clipboard artifacts retain card data on agent endpoints.
- Review telephony and CRM integrations together, because hidden middleware often expands scope beyond the obvious systems.
- Photograph or export evidence for each deficiency at the time of inspection so remediation can be tied to the exact condition found.
- Treat unclear data ownership or undocumented routing as a scope risk until the flow is fully explained.

Common use cases
Frequently asked questions
What does this PCI DSS Telephone Payment Scope Review cover?
It covers the people, devices, systems, and data flows involved when card payments are taken by phone. That includes agent workstations, headsets, softphones, call recording, telephony segmentation, and any integrations that touch cardholder data. It is designed to document what is in scope and where controls or exceptions need follow-up.
When should we use this template?
Use it during initial PCI scoping, after a telephony or call-recording change, before a QSA assessment, or when a business unit starts taking payments by phone. It is also useful after a merger, contact-center relocation, or system migration because those changes often expand scope. If the payment flow has changed, the scope review should be rerun.
Who should run this inspection?
A security, compliance, or PCI program owner should lead it, with input from contact-center operations, IT, telephony administrators, and the business owner for the payment channel. If scope is unclear, a Qualified Security Assessor should be consulted. The template also works well when an internal auditor is documenting evidence before external review.
How often should a telephone payment scope review be performed?
It should be performed at least whenever the payment environment changes, and many organizations also run it on a scheduled cadence such as quarterly or annually. The right frequency depends on how often agents, telephony tools, and recording platforms change. Any new integration, routing change, or recording policy update should trigger a fresh review.
What are the most common mistakes this template helps catch?
Common misses include local cardholder data stored on agent endpoints, call recordings that capture card entry without masking or pause controls, and third-party tools receiving payment data unnecessarily. Teams also overlook shared workstations, remote agents, and hidden integrations between telephony and CRM systems. This template forces those paths to be documented and reviewed.
Does this template replace a PCI DSS assessment?
No. It is a scoping and inspection tool that helps you identify what needs to be assessed and where the risks are. It supports PCI DSS readiness, but it does not certify compliance on its own. Use it to prepare evidence, clarify boundaries, and reduce surprises during formal assessment.
How does this help with call recording and telephony integrations?
The template prompts you to verify whether recordings pause or mask during card entry, whether retention and access controls are documented, and whether telephony systems are segmented from other networks. It also asks you to map every system that touches payment-call data end to end. That makes hidden data paths easier to find.
Can we customize this for different contact-center setups?
Yes. You can adapt it for on-premises PBX, cloud contact center, remote agents, shared workstations, or hybrid environments. The structure is intentionally flexible so you can add local business units, specific telephony vendors, or additional evidence fields without changing the core scope logic.
