Questions people ask

Can MediaSFU add a click-to-call button to a website?

Yes. MediaSFU supports click-to-call and related widget surfaces for browser-based voice and communication workflows.

Can widgets connect to AI agents?

Yes. Widget flows can include AI agents, web agents, call surfaces, and human handoff paths depending on configuration.

Do widgets replace custom SDK work?

Widgets are the fastest launch path. Teams can later move to SDK or API integration when the product needs custom behavior.
