Check browser call support
Go beyond API-name detection. This check verifies a live Dadaphone response and completes an in-browser WebRTC offer, answer, ICE exchange, and data-channel delivery without opening your microphone.
What this tool checks
Dadaphone tests the secure context, live edge route, local WebRTC negotiation and delivery, Opus capability, Web Audio, media capture, and available permission states. Required and optional checks are labelled separately.
Why browser capability matters
Dadaphone needs a secure browser context, microphone support, WebRTC, and browser audio playback for a call. Missing support can stop a call before it begins.
What the check can confirm
The result proves that a same-origin edge request completed and that two local peer connections exchanged SDP, ICE candidates, and a data-channel message. It also reports Opus and media API support plus available permission state.
What it cannot confirm
The check does not test carrier routing, the recipient’s number, payment status, or a live call connection. Check the complete number and rate separately before you call.
Limits of this tool
The WebRTC loopback validates this browser engine only. It cannot prove TURN traversal, a working microphone, the production signalling service, carrier routing, or a remote recipient.
Questions before you call
Does a passed loopback prove a real call will connect?
No. The loopback validates the local browser engine. A real call still depends on microphone access, signalling, network traversal, Dadaphone routing, and the recipient network.
