Using ContactPad with WebRTC

If your Vonage Contact Center account is enabled to use WebRTC, you have the feature switched on for your individual agent account, and you have added the WebRTC for Vonage Contact Center extension to your Google Chrome or Microsoft Edge (Chromium) browser, you can make and receive calls using your usual computer or device; you do not need a physical telephone. For more information, see ContactPad with WebRTC.

We only support using ContactPad with WebRTC:

  • When using the WebRTC for Vonage Contact Center extension in Google Chrome or Microsoft Edge (Chromium).
  • In the most recent version of Chrome or Edge for Windows and Mac OS X.

    We develop and test the WebRTC for Vonage Contact Center extension in the latest versions of Chrome and Edge only.

Supervisor monitoring does not work with WebRTC.

Before you use ContactPad with WebRTC, remember to set up audio devices properly. These devices include microphone, speakers, recording and playback equipment, and browser.

The first time you use ContactPad with WebRTC, your browser might ask permission to use the device's audio hardware. In both Chrome and Edge, Allow and Block buttons appear. Click Allow.

Whenever you log in to or reload ContactPad, a Connecting To WebRTC Extension message, a Connecting To Telephony message, or both, appear briefly in ContactPad.

Best practices for using ContactPad with WebRTC

When using ContactPad with WebRTC, you should follow these best practices:

  • Web browser:
    • Reduce the number of windows and tabs you have open.
    • Regularly clear browsing history, cookies, and cached images and files, ideally weekly.
    • Enable Periodic extension reload for the WebRTC for Vonage Contact Center extension. For information, see Optional settings for WebRTC for Vonage Contact Center extension
  • Hardware:
    • Upgrade computer hardware if CPU or memory limits are being reached.
    • Regularly restart computer, ideally daily.
    • Use a wired Ethernet connection (rather than a wireless connection) to connect to the network. Disable WiFi.
  • Software
    • Remove any non-essential applications.
    • Update audio and headset drivers to their latest versions.
  • Other:
    • Configure your headset as the default device for audio (playback and recording).
    • Disable exclusive mode settings for your audio (playback and recording) devices.

Setting up WebRTC for ContactPad

To use WebRTC in ContactPad, you or your supervisor must switch the feature on for your individual ContactPad. For information about switching this on, see Turning on WebRTC in ContactPad later in this page. You must then add the WebRTC for Vonage Contact Center extension to your Chrome or Edge browser. For information about adding the extension, see Adding the WebRTC for Vonage Contact Center extension to your browser later in this page.

Turning on WebRTC in ContactPad

To use ContactPad with WebRTC, perform the following steps:

  1. In ContactPad, click Settings.

    A new dialog box appears. If your account has been configured to use WebRTC and you are permitted to control the feature yourself, the Use Softphone check box is available.

    Enabling WebRTC

  2. Select the Use Softphone check box to use ContactPad with WebRTC. Click Save. Next time you make or receive a call, ContactPad will use WebRTC.

You can use the Use Softphone check box to switch between using WebRTC and a physical telephone whenever you need to, without help from your supervisor.

Your supervisor can also switch on WebRTC for you. For information for supervisors to switch on WebRTC for your account, see How do I enable an agent to use ContactPad with WebRTC? in Configuring individual users. Whether you or your supervisor switches on WebRTC, the two methods have the same effect; updating one will change the other.

Adding the WebRTC for Vonage Contact Center extension to your browser

To use ContactPad with WebRTC, you must add the WebRTC for Vonage Contact Center extension to your Chrome or Edge browser. This extension enables you to configure options such as preferred audio devices, secondary ringing, and auto-answer. On adding the extension, you can also browse away from the browser window containing ContactPad during a call. You can open and close any number of Chrome or Edge browser windows—even the window containing ContactPad—and the call remains connected. You can also use the extension to answer and control calls from any Chrome or Edge browser window.

To add the extension to your browser, perform the following tasks:

  1. Depending on which browser you want to use, go to one of the following pages:
  2. Click to add the extension to your browser.
    If prompted, click to confirm that you want to add the extension. A new browser window opens.
  3. At this point a pop up may appear requesting to use your microphone—if so, you will also see an error message in red: WebRTC permissions denied. Click to allow the extension to use your microphone—the error message is replaced by a success message in green: WebRTC permissions granted.

  4. In the new browser window, check that all the messages are green and correct any errors.WebRTC extension success

Now, when you receive an incoming call, click WebRTC for Vonage Contact Center's icon in any Chrome or Edge window to answer and control the call. For information about receiving a call using ContactPad with WebRTC, see Receiving an inbound call using ContactPad with WebRTC later in this page.

You can also click the icon during an existing outbound call to control that call in the same way. For information about making an outbound call using ContactPad with WebRTC, see Making an outbound call using ContactPad with WebRTC later in this page.

You can open and close any number of Chrome and Edge browser windows—even the window containing ContactPad—and the call remains connected.

ContactPad must be open and you must be logged in to ContactPad when an incoming call first arrives or you make an outbound call.

Optional settings for WebRTC for Vonage Contact Center extension

When you have added the WebRTC for Vonage Contact Center extension to your Chrome or Edge browser, you can optionally configure various settings.
