SignalWire

Voice, SMS, video, and every communications primitive on one carrier-grade platform, built by the team that wrote the engine. Not a CPaaS wrapper.

The page contrasts CPaaS, which places state management in customer code, with SignalWire's platform, which manages call state, lifecycle, and routing with low-latency AI built in.

The platform runs real-time AI on code rather than prompts and includes deterministic guardrails, about 1.2-second latency, and control over every call.

The page presents a voice-first demo for an AI real estate agent.

The page says its engineers wrote FreeSWITCH and the platforms running on top of it.

Transparent, usage-based pricing for SignalWire's programmable voice, messaging, video, fax, MFA, and AI agent APIs.

Compare SignalWire Basic, Premium, and Enterprise support plans, pricing, response times, SLAs, and 24/7 options for mission-critical apps.

LiveKit handles video rooms well. When the use case is voice AI answering phone calls, the architecture needs native telephony, not a WebRTC bridge.

SignalWire is the communications control plane built by the team that wrote FreeSWITCH: the real-time voice engine the industry already runs on.

SignalWire offers assistance with platform evaluation, migration from another provider, support, and community help.

Build AI voice agents, contact centers, and unified communications on one programmable platform. One control plane, no vendor stitching.

SignalWire, an API platform for building real-time communications applications, raises $30 million in Series B funding. Prosperity7 Ventures leads the round, which SignalWire says will help build infrastructure for Telecom 2.0.
