View as MarkdownOpen in Claude

SignalWire treats all real-time communication channels as part of a unified calling layer. Whether you’re building an AI-powered phone agent, a traditional IVR, a video conferencing app, or a cloud fax workflow, it all runs on the same platform, the same APIs, and the same infrastructure.

AI

Deploy intelligent voice agents powered by LLMs. Build with the Server SDK, SWML, or the Dashboard — no telephony expertise required.

Voice

Make and receive phone calls over PSTN, SIP, and WebRTC. Build IVRs, call routing, recording, and conferencing applications.

Video

Add programmable video conferencing to your application with a cloud-based MCU, low latency, and a unified stream for all participants.

Fax

Send and receive faxes programmatically with HIPAA-ready, SOC 2 Type II compliant infrastructure.

WhatsApp

Take calls placed from WhatsApp on your Meta-verified business number, and route them like any other call.
