Mute the Operator's Microphone from the Application CallCardSetMute

Scope: placement — registration of the placement, telephony — registration of the call that raises the card

Who can execute the command: any user

The CallCardSetMute command mutes or unmutes the operator's microphone in the call card.

How to Call the CommandHow to Call the Command

The command is invoked from the widget with the BX24.placement.call method. The third argument is the callback function, which receives the result of the command.

BX24.placement.call('CallCardSetMute', {muted: true}, function (result) {
            console.log(result);
        });

BX24.ready(function () {
            BX24.init(function () {
                BX24.placement.call('CallCardSetMute', {muted: true}, function (result) {
                    console.log(result);
                });
            });
        });
        

// $b24 is an already-initialized SDK instance (see the SDK "Get started" guide)
        import type { B24Frame } from '@bitrix24/b24jssdk'
        
        declare const $b24: B24Frame
        
        await $b24.placement.call('CallCardSetMute', { muted: true })
        

<!-- Load the SDK (UMD build); it is exposed as the global B24Js -->
        <script src="https://unpkg.com/@bitrix24/b24jssdk@1/dist/umd/index.min.js"></script>
        <script>
          document.addEventListener('DOMContentLoaded', async () => {
            const $b24 = await B24Js.initializeB24Frame()
        
            const result = await $b24.placement.call('CallCardSetMute', {muted: true})

Returned DataReturned Data

An empty array on a successful call.

If the microphone is already in the requested state, the command returns an empty array right away: the card does not change and the BackgroundCallCard::muteButtonClick event does not occur.

ErrorsErrors

The command error arrives in the same callback function: instead of the usual result, it receives an array with an object whose result equals error.

[
            {
                "result": "error",
                "errorCode": "Call card is undefined"
            }
        ]
        

errorCode ValueserrorCode Values

If the command is invoked in another placement, the callback function will not be invoked at all: the placement interface ignores an unknown command. To check that the CallCardSetMute command is available, use the BX24.placement.getInterface method.
