Concepts

Sessions, configuration, and capability discovery — the building blocks every other SDK page assumes.

📄️Sessions and modes

A session is a server-issued realtime context. Every SDK action runs inside one. Modes decide audio routing and protocol shape.

DelphiClient constructor options — API endpoints, session-token proxy, ICE servers, codec preference, idle timeout, and logger.

Inspect what an endpoint supports before opening a session — getCapabilities, hasCapability, assertCapability, assertEndpointCapability.
