Bandwidth is a cloud communications API platform and licensed US carrier — providing voice calling, SMS/MMS messaging, and emergency 911 services through APIs that enterprise software companies embed into their products. Bandwidth's carrier status (owning its own network rather than reselling) provides quality, reliability, and cost advantages for high-volume enterprise communications. AI capabilities in Bandwidth's platform support the AI-powered communications use cases that enterprises are building — AI voice agents, conversational IVR, AI-enhanced customer service calling, and AI-powered messaging. Bandwidth's AI Gateway enables enterprises to deploy AI voice agents that handle inbound and outbound calling — connecting AI models to phone calls for automated customer service, appointment reminders, and sales outreach. The Maestro platform orchestrates communications workflows — connecting Bandwidth's voice and messaging to AI providers, contact centre platforms, and business applications in programmable sequences. 911 as a Service enables enterprise software companies to provide accurate emergency calling from cloud communication applications — a regulatory requirement for many business communication applications. With customers including Zoom, RingCentral, and Dialpad as platform partners, Bandwidth validates as the enterprise communications infrastructure layer beneath major unified communications platforms.
Bandwidth AI runs as ml platform software built around audio and text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web and api.
