Detailed Description

SIP (Session Initiation Protocol) DTMF payload carried via data packets.

SIP is a signalling protocol used in VoIP telephony. LiveKit supports SIP trunking, which bridges traditional phone calls into LiveKit rooms. DTMF (Dual-Tone Multi-Frequency) tones are the signals generated when phone keypad buttons are pressed (0-9, *, #). This struct surfaces those tones so that applications handling SIP-bridged calls can react to caller input (e.g. IVR menu selection).

The documentation for this struct was generated from the following file:
