Code Snippet

Create TwiMl

@PostMapping(value = "/twiml", produces = "text/xml")
    public String generateTwiml() throws URISyntaxException {

        System.out.println( "IncomingCallWebhook().generateTwiml()" );

        Conference conferenceBuilder = new Conference.Builder( CONFERENCE_ROOM_NAME )//
                .record( Conference.Record.RECORD_FROM_START )//
                .recordingStatusCallback( new URI( PUBLIC_URL + "recordCallBack" ) )//
                .recordingStatusCallbackEvents( Conference.RecordingEvent.COMPLETED )//
                .startConferenceOnEnter( true ).endConferenceOnExit( true ).statusCallback( new URI( PUBLIC_URL + "callback" ) )//
                .statusCallbackMethod( HttpMethod.POST )//
                .statusCallbackEvents( Arrays.asList( Conference.Event.START, Conference.Event.END, Conference.Event.JOIN, Conference.Event.LEAVE, Conference.Event.HOLD, Conference.Event.SPEAKER ) ).build();

        Say say = new Say.Builder( "Hi! Welcome" ).voice( Voice.WOMAN ).language( Language.EN_US ).build();

        Record record1 = new Record.Builder().timeout( 10 ).action( new URI( PUBLIC_URL + "recordVmCallback" ) ).method( HttpMethod.POST )//
                .recordingStatusCallback( new URI( PUBLIC_URL + "recordVmUrl" ) ).recordingStatusCallbackMethod( HttpMethod.POST ).recordingStatusCallbackEvents( Record.RecordingEvent.COMPLETED ).build();

        Say say2 = new Say.Builder( "I did not receive a recording" ).build();

        return new VoiceResponse.Builder().say( say )// .record( record1 ).say( say2 )// .play( play )
                .dial( new Dial.Builder().conference( conferenceBuilder ).build() ).build().toXml();
    }

Create conference code

@PostMapping(value = "/createConference")
    public ResponseEntity<ObjectNode> createConference( @RequestBody ObjectNode objectNode ) throws URISyntaxException, InterruptedException {

        System.out.println( "IncomingCallWebhook().createConference() objectNode = " + objectNode );

        ObjectNode response = JsonNodeFactory.instance.objectNode();

        Twilio.init( objectNode.get( "sid" ).asText(), objectNode.get( "auth" ).asText() );

        Call call = Call.creator( new PhoneNumber( objectNode.get( "to" ).asText() ), new PhoneNumber( objectNode.get( "from" ).asText() ), new URI( PUBLIC_URL + "twiml" ) )//
                .setStatusCallbackEvent( Arrays.asList( "initiated", "ringing", "answered", "completed" ) ).setStatusCallback( new URI( PUBLIC_URL + "call/callback" ) )//
                // .setRecord( true )//
                .setStatusCallbackMethod( HttpMethod.POST ).create();

        response.put( "callid", call.getSid() );

        return ResponseEntity.ok( response );

    }

Add Participant

@PostMapping(value = "/addParticipant")
    public ResponseEntity<String> addParticipant( @RequestBody ObjectNode objectNode ) throws URISyntaxException {

        System.out.println( "IncomingCallWebhook().updateConference() objectNode = " + objectNode );

        Twilio.init( objectNode.get( "sid" ).asText(), objectNode.get( "auth" ).asText() );

        Participant participant = Participant//
                .creator( objectNode.get( "cid" ).asText(), new PhoneNumber( objectNode.get( "from" ).asText() ), new PhoneNumber( objectNode.get( "to" ).asText() ) )//
                // .setRecord( true )
                .create();

        return ResponseEntity.ok( participant.toString() );

    }

End confernce

@PostMapping(value = "/updateConference")
    public ResponseEntity<String> updateConference( @RequestBody ObjectNode objectNode ) throws URISyntaxException {

        System.out.println( "IncomingCallWebhook().updateConference() objectNode = " + objectNode );

        Twilio.init( objectNode.get( "sid" ).asText(), objectNode.get( "auth" ).asText() );

        com.twilio.rest.api.v2010.account.Conference conference = com.twilio.rest.api.v2010.account.Conference.updater( objectNode.get( "cid" ).asText() ).setStatus( com.twilio.rest.api.v2010.account.Conference.UpdateStatus.COMPLETED ).update();

        return ResponseEntity.ok( conference.toString() );

    }
