SignalWire

Programmable Unified Communications Platform

Real-time voice, messaging, video, and AI APIs for developers.

SignalWire Powers Real-Time Communications With a Unified Control Plane

SignalWire frees developers from stitching together fragile third-party services by running voice, messaging, video, and AI on a single owned infrastructure. Built by the creators of FreeSWITCH, the platform gives teams direct control over call state, routing, and lifecycle, so the same workflow that handles ten calls scales cleanly to ten thousand, without rebuilding the foundation.

Products & Services

SignalWire serves developers, enterprises, and contact center teams with programmable voice, messaging, video, and AI agent capabilities, all orchestrated from a single communications control plane.

AI Voice Agents

  • AI Agent API: Deploy conversational voice agents that respond, route, and act in real time.
  • Multi-Agent Orchestration: Transfer callers between specialized AI agents and humans with full context preserved.
  • Built-in RAG (Datasphere): Ground AI agents in your own documents for accurate, traceable responses.
  • Context and Steps: Define declarative agent workflows that keep AI on task through every stage of a call.

Programmable Voice

  • Voice API: Build dynamic call routing, IVRs, auto-dialers, and recording pipelines with developer-first APIs.
  • Click-to-Call: Embed WebRTC-powered call buttons directly into any website or application.
  • Real-Time Transcription: Capture live call transcripts and stream speech data to your application via webhooks.
  • Real-Time Voice Translation: Translate phone calls across thousands of languages with a single line of SWML.

Messaging

  • Messaging API: Send and receive SMS at scale with programmable routing and workflow automation.
  • SMS Follow-Up: Trigger post-call text messages automatically from within live voice workflows.

Communications Infrastructure

  • Call Fabric: Address every communication resource (numbers, SIP endpoints, agents, video rooms) as programmable objects on one control plane.
  • SIP and BYOC: Connect existing carriers or route calls through your own infrastructure with full SIP support.
  • Data Residency and Compliance: Route data through in-region infrastructure to meet GDPR, HIPAA, and sovereignty requirements.

About SignalWire

SignalWire gives developers and enterprises direct control over the full lifecycle of real-time communications. Built by the creators of FreeSWITCH, the open-source communications platform with over 15 years of development behind it, SignalWire moves beyond traditional CPaaS by offering a unified control plane that orchestrates voice, messaging, video, and AI from a single infrastructure layer.

The platform owns its telecom infrastructure end to end, delivering sub-500ms response times without relying on third-party services. Developers use SignalWire's APIs, SDKs, and SignalWire Markup Language (SWML) to build everything from AI voice agents and programmable contact centers to real-time transcription and translation systems. SignalWire holds SOC 2 Type II certification and aligns with GDPR, HIPAA, CCPA, and PCI-DSS standards.
