Yes, LiveKit provides a way to send DTMF (Dual-Tone Multi-Frequency) signals. You can use the

publishDtmf

API on the

localParticipant

object to transmit DTMF tones. This is particularly useful for relaying signals to telephone users via SIP participants. The

publishDtmf

function requires two parameters: • `code`: An integer representing the DTMF signal code • `digit`: A string representing the DTMF digit (e.g., "1", "#", "*") Here is an example usage:

// publishes 123# in DTMF
await localParticipant.publishDtmf(1, '1');
await localParticipant.publishDtmf(2, '2');
await localParticipant.publishDtmf(3, '3');
await localParticipant.publishDtmf(11, '#');
