Check calling

Sign in, then test. This checks a real relay connection using two browser peers and a test message. It does not place a call to anyone.

Microphone access is requested only when you press this button. No audio is saved or sent.

Two-phone test

On both phones, sign in to UCall, accept the private connection and keep the app open. Choose the contact, press Call, and answer on the other phone. Confirm each person can hear the other, then hang up. Repeat on separate Wi-Fi networks.

A relay test passing does not prove background ringing or a two-phone call.

Operator setup

In the project console Setup, connect ucall_turn using the Cloudflare TURN Key API Token. Set ucall_turn_key_id to the corresponding TURN Key ID. Keep the token in secure Setup; do not paste it into chat.
