The short answer

MediaSFU runs AI voice agents in browser calls, phone calls over SIP/PSTN, website widgets and your own apps. You connect your own speech and language providers; MediaSFU bills the agent runtime and the call audio per minute.

Questions people ask

Can MediaSFU run AI voice agents over real phone calls?

Yes. MediaSFU includes SIP/PSTN setup paths for phone workflows, and those can be paired with AI pipeline and handoff patterns.

Can we start without building a full custom voice app?

Yes. Start with embeddable widgets or guided surfaces, then move to SDK and API control once the workflow is validated.

Is MediaSFU only an AI voice tool?

No. Voice agents are part of a broader real-time communication platform that also includes meetings, WebRTC media, telephony, translation, recording, and widgets.
