Your phone system shouldn’t be a black box. Whether you’re building a custom CRM integration, automating your contact center workflows, or developing a bespoke application for your team, RingQ’s REST API gives developers direct, programmatic access to the call controls that power your business communications.
With 17 endpoints across four categories — Call Control, Monitoring, Recording, and Voicemail & Queue — the RingQ API is purpose-built for teams who want to go beyond the web app and build exactly the telephony experience they need.
What Can You Build with the RingQ API?
Here’s the short answer: almost anything. Here’s the longer one.
Call Control — Initiate and Manage Calls Programmatically
The Call Control category is where most integrations begin. These six endpoints let your applications interact with live calls without any human clicking a button in a softphone.
Make Call — Trigger an outbound call directly from your application
This is the backbone of click-to-call functionality in CRMs, helpdesk platforms, and sales tools. When a sales agent clicks a phone number in your system, your app fires the Make Call API in the background — no manual dialing required.
Transfer Call — Move a live call to another extension, agent, or number
Combine this with your CRM’s customer data to route high-value callers automatically to senior agents or account managers.
Divert Call — Redirect an incoming call before it reaches its intended destination
Perfect for dynamic call routing scenarios where your application logic — not a static IVR — should decide where a call goes.
Divert to Voicemail — Send a call directly to voicemail
When an agent is unavailable or when your application determines the call doesn’t need a live response send the call to voicemail.
Drop Call — Terminate a call programmatically
Useful in automated outbound scenarios, compliance workflows, or when your application detects a condition that requires ending the call immediately.
Pickup Call — Pick up a ringing call via API
Enable screen-pop integrations where answering happens in your application, not from the RingQ interface.
Monitoring — Supervise Live Calls in Real Time
Contact center managers know that real-time visibility is everything. The Monitoring endpoints give supervisors and quality assurance tools programmatic access to live conversations.
Listen Call — Join a call silently
Monitor a conversation without either party knowing. Essential for quality assurance and compliance monitoring workflows.
Whisper Call — Speak to the agent on a live call
Speak to an agent without the customer hearing. Supervisors can coach agents mid-call — prompting the right answer, flagging an issue, or guiding a difficult conversation — all through your own application.
Barge-In Call — Join an active call
Join the call as a full participant when a situation escalates. Instead of waiting for an agent to transfer a call, a supervisor can enter the conversation directly.
Join Call — Add yourself or another party to an existing call
Enable multi-party conversations, warm handoffs, and team-assist scenarios without manual conference setup.
Recording — Start, Stop, Retrieve, and Link Recordings on Demand
Recording is one of the most integration-heavy areas of any telephony platform. RingQ provides four dedicated recording endpoints that give you full lifecycle control.
Record Start / Record Stop — Begin or end a recording at any point during a live call
This is critical for compliance use cases where only certain parts of a conversation need to be captured — for example, pausing recording when a customer reads out payment card details (a PCI DSS requirement) and resuming afterwards.
Recording List — Retrieve a list of recordings programmatically
Feed this into your CRM, your data warehouse, or your quality assurance platform without anyone manually downloading files.
Recording Link — Generate a direct link to a specific recording
Attach it to a CRM record, send it in a notification, or surface it in your internal dashboards automatically after every call.
Voicemail & Queue Management
Voicemail Delete — Clean up voicemail storage programmatically, useful in high-volume environments where automated workflows process and archive messages.
Queue Login / Queue Logout — Log agents into or out of call queues via API. This is a game-changer for workforce management integrations. When an agent clocks in via your HR system, your application can automatically log them into the right queues. When they clock out, they’re removed — no forgotten queue sessions, no missed calls sitting in an empty queue.
Real-World Integration Examples
CRM Click-to-Call: Your sales team lives in a CRM. With the Make Call API, every phone number in your CRM becomes a one-click call trigger. The call is initiated via the RingQ API, and a webhook fires when the call ends — automatically logging the duration, outcome, and recording link back to the contact record.
PCI-Compliant Payment Calls: When a customer says “I’ll read my card number now,” your application calls Record Stop. After they confirm, Record Start resumes. No sensitive card data ever touches a recording. The Recording List and Recording Link endpoints keep everything else auditable and accessible.
Workforce Management Automation: Connect your scheduling software to the Queue Login and Queue Logout endpoints. Agents are enrolled in the right queues at shift start and removed at shift end — automatically, based on your roster data.
Real-Time Supervisor Dashboards: Build a live monitoring interface that uses the Whisper and Barge-In endpoints as action buttons. When a supervisor sees a struggling agent on their dashboard, they can intervene with a single click — no hunting through a phone system menu.
Getting Started
The RingQ API uses REST with POST requests across all 17 endpoints. Authentication is handled via your PBX Host/FQDN, API Key, and Secret Key — all configurable in the RingQ API Builder at ringq.com/api-list.
The API Builder also generates ready-to-use curl commands so you can test any endpoint against your live system before writing a single line of application code.
The Bigger Picture
Most PBX platforms treat telephony as a closed system — you use the interface they give you, and that’s that. RingQ’s API is a deliberate break from that model. By exposing call control, monitoring, recording, and queue management as REST endpoints, RingQ makes it possible to embed enterprise telephony capabilities directly into the tools your team already uses.
You’re not building around your phone system. You’re building with it.
