About SignalWire
SignalWire is an advanced cloud communications platform, founded by the original developers of FreeSWITCH, offering a robust infrastructure for building real-time communication applications. Its core offering is a programmable unified communications control plane, which provides deeper control over routing, media, and state management compared to traditional CPaaS providers. The platform exposes a comprehensive set of APIs and SDKs for Voice, SMS/MMS Messaging, Video Conferencing, Fax, and Multi-Factor Authentication. A key feature is the ability to build and deploy voice-driven AI agents that can integrate with business systems in real-time. SignalWire is designed for high scalability and reliability, enabling use cases from simple SMS notifications and IVRs to complex contact centers and AI-driven customer interactions.
