xAI is preparing to promote its Voice Agent Builder on Grok, allowing users to build custom agents that can answer their phone calls.

> Let Grok answer your phone

> I’ll help you deploy your first agent in just a few minutes without a single line of code.

> Create an AI that picks up your calls and talks in a natural voice. Tell it what to handle — questions, bookings, messages — and we'll give you a free number so it can start taking real calls in minutes.

That would be interesting 👀
