Once participants have joined the conference, the wait music comes to an end, a beep is played, and the conference call begins.### A Moderated Conference Call xml moderated-conference-room javascriptconst { RestClient } = require(@signalwire/compatibility-api);const response = new RestClient.LaML.VoiceResponse();dial = response.dial();dial.conference(moderated-conference-room, { startConferenceOnEnter: false });console.log(response.toString()); phpdial(); $dial->conference(moderated-conference-room, array( startConferenceOnEnter => false )); echo $response;?> csharpusing Twilio.TwiML;using Twilio.TwiML.Voice;using System;class Example{ static void Main() { var response = new VoiceResponse(); var dial = new Dial(); dial.Conference(moderated-conference-room, startConferenceOnEnter: false); response.Append(dial); Console.WriteLine(response.ToString());; }} pythonfrom signalwire.voice_response import VoiceResponse, Dial, Conferenceresponse = VoiceResponse()dial = Dial()dial.conference(moderated-conference-room, start_conference_on_enter=False)response.append(dial)print(response) rubyrequire signalwire/sdkresponse = Signalwire::Sdk::VoiceResponse.new do |response| response.dial do |dial| dial.conference(moderated-conference-room, start_conference_on_enter: false) endendputs response.to_s You can set the startConferenceOnEnter to **false** so that a group of participants can join in the conference room but the conference cannot begin until the moderator has entered the call. As the participants wait for the conference to begin, hold music will be playing in the background.### Start A Moderated Conference Call xml moderated-conference-room javascriptconst { RestClient } = require(@signalwire/compatibility-api);const response = new RestClient.LaML.VoiceResponse();dial = response.dial();dial.conference(moderated-conference-room, { startConferenceOnEnter: true, endConferenceOnExit: true,});console.log(response.toString()); phpdial(); $dial->conference(moderated-conference-room, array( startConferenceOnEnter => true, endConferenceOnExit => true ) ); echo $response;?> csharpusing Twilio.TwiML;using Twilio.TwiML.Voice;using System;class Example{ static void Main() { var response = new VoiceResponse(); var dial = new Dial(); dial.Conference(moderated-conference-room, startConferenceOnEnter: true, endConferenceOnExit: true); response.Append(dial); Console.WriteLine(response.ToString());; }} pythonfrom signalwire.voice_response import VoiceResponse, Dial, Conferenceresponse = VoiceResponse()dial = Dial()dial.conference(moderated-conference-room, start_conference_on_enter=True, end_conference_on_exit=True)response.append(dial)print(response) rubyrequire signalwire/sdkresponse = Signalwire::Sdk::VoiceResponse.new do |response| response.dial do |dial| dial.conference(moderated-conference-room, start_conference_on_enter: true, end_conference_on_exit: false) endendputs response.to_s Now, since the moderator has joined in on the conference call, startConferenceOnEnter is set to **true** which means the conference can begin. All the participants that were waiting on hold will now be connected to the conference room; the hold music will come to an end and a beep notification will play indicating conference entrance. Once the moderator leaves the call, the conference will come to an end and all participants will be disconnected from the call.### Joining a Conference Call Muted (Monitor) xml ConferenceRoom javascriptconst { RestClient } = require(@signalwire/compatibility-api);const response = new RestClient.LaML.VoiceResponse();dial = response.dial();dial.conference({ muted: true }, ConferenceRoom);console.log(response.toString()); phpdial(); $dial->conference(ConferenceRoom, array( muted => true )); echo $response;?> csharpusing Twilio.TwiML;using Twilio.TwiML.Voice;class Example{ static void Main() { var response = new VoiceResponse(); var dial = new Dial(); dial.Conference(ConferenceRoom, muted: true); response.Append(dial); Console.WriteLine(response.ToString());; }} pythonfrom signalwire.voice_response import VoiceResponse, Dial, Conferenceresponse = VoiceResponse()dial = Dial()dial.conference(ConferenceRoom, muted=True)response.append(dial)print(response) rubyrequire signalwire/sdkresponse = Signalwire::Sdk::VoiceResponse.new do |response| response.dial do |dial| dial.conference(ConferenceRoom, muted: true) endendputs response.to_s Participants who enter a conference call muted can hear the other participants in the call who are unmuted. However, the unmuted participants cannot hear the muted callers. Muting and unmuting can be enabled and disabled in real-time via a REST API.### Coaching A Conference Call xml Example-Room javascriptconst { RestClient } = require(@signalwire/compatibility-api);const response = new RestClient.LaML.VoiceResponse();dial = response.dial();dial.conference(Example-Room, { coach: AgentCallSid });console.log(response.toString()); phpdial(); $dial->conference(Example-Room, array( coach => AgentCallSid )); echo $response;?> csharpusing Twilio.TwiML;using Twilio.TwiML.Voice;using System;class Example{ static void Main() { var response = new VoiceResponse(); var dial = new Dial(); dial.Conference(Example-Room, coach: AgentCallSid); response.Append(dial); Console.WriteLine(response.ToString());; }} pythonfrom signalwire.voice_response import VoiceResponse, Dial, Conferenceresponse = VoiceResponse()dial = Dial()dial.conference(Example-Room, coach=AgentCallSid)response.append(dial)print(response) rubyrequire signalwire/sdkresponse = Signalwire::Sdk::VoiceResponse.new do |response| response.dial do |dial| dial.conference(Example-Room, coach: ) endendputs response.to_s ### Recording a Conference Call xml ConferenceCall javascriptconst { RestClient } = require(@signalwire/compatibility-api);const response = new RestClient.LaML.VoiceResponse();dial = response.dial();dial.conference(ConferenceCall, { record: record-from-start, recordingStatusCallback: https://www.example.com/recording_update,});console.log(response.toString()); phpdial(); $dial->conference(ConferenceCall, array( record => record-from-start, recordingStatusCallback => https://www.example.com/recording_update ) ); echo $response;?> csharpusing Twilio.TwiML;using Twilio.TwiML.Voice;using System;class Example{ static void Main() { var response = new VoiceResponse(); var dial = new Dial(); dial.Conference(ConferenceCall, record: record-from-start, recordingStatusCallback: new Uri(https://www.example.com/recording_update)); response.Append(dial); Console.WriteLine(response.ToString());; }} pythonfrom signalwire.voice_response import VoiceResponse, Dial, Conferenceresponse = VoiceResponse()dial = Dial()dial.conference(ConferenceCall, record=record-from-start, recording_status_callback=https://www.example.com/recording_update)response.append(dial)print(response) rubyrequire signalwire/sdkresponse = Signalwire::Sdk::VoiceResponse.new do |response| response.dial do |dial| dial.conference(ConferenceCall, record: record-from-start, recording_status_callback: https://www.example.com/recording_update) endendputs response.to_s The recording of the conference call will begin when at least two participants join the conference room. A recordingStatusCallback will be sent when the recording is accessible.## Notes On Usage- You can freely name the conference room to fit your preference. However, only callers within a project can join in on a named conference room. Callers from separate projects will not be able to connect to that same conference room.- You can customize the background music as callers are waiting to join a conference call- Conferences will not begin unless there are 2 or more parties present.
