Each Verto call has three distinct muting actions:

  • on: means audio is activated and the call is not muted
  • off: means audio is deactivated and the call is muted
  • toggle: changes the mute state of the call to the opposite value

Preparing interface

Adding buttons...

<div class="container">
  <h1>Verto - Demo Application</h1>
  <!-- ... -->
  <button id="mute-call">Mute call</button>
  <button id="unmute-call">Unmute call</button>
  <button id="mute-unmute-call">Mute/Unmute call</button>
</div> <!-- /container -->

Binding click

Inside our bootstrap function add event bindings with a function callback so that we know when user clicked our Mute buttons:

function bootstrap(status) {
  // ...
  document.getElementById("mute-call").addEventListener("click", muteCall);
  document.getElementById("unmute-call").addEventListener("click", unmuteCall);
  document.getElementById("mute-unmute-call").addEventListener("click", muteUnmuteCall);

Muting a call

We have to create the callbacks we've specified to the event bindings inside our main function.

function muteCall() {

function unmuteCall() {

function muteUnmuteCall() {

Try it and see what each button can do to the active call.
