Authenticated example

Make a real API call.

Answer your phone to hear a short demonstration in Polish. The call ends automatically within 60 seconds and is not recorded. Use a number you are authorized to call.

Authentication required

The access token stays only in this page's memory and disappears when the page is refreshed.

Generated server integration kit

Tenant-bound API client

Each customer application receives its own confidential OIDC identity and a client generated from the live OpenAPI contract. The kit owns short-lived tokens, correlation and idempotency without exposing SIP infrastructure.

Framework-neutral browser package

@telephony-core/browser-phone

The SDK uses the access token already obtained by your host product. It resolves the authenticated user's phone identity and never accepts a static SIP password.
