FAQ

Questions buyers and AI search engines ask

For many agents, yes. Keep a hardware fallback for reception desks and power users who want a physical hook switch. The PBX treats both as SIP endpoints.

That is why TURN is in the architecture. Without a relay, “works in the office” is not a product.

Yes — click-to-call as a guest session into a queue. Different credential model than an authenticated agent phone.

We design for autoplay, audio session and background limits. A PWA helps; a native app is a later increment if you need true background ringing.

Need this built?

Send the current architecture, call volume, carriers and the workflow you need to automate or productize. Discovery can start from a broken PBX or a blank product brief.
