The 3CX web conferencing platform enables video and voice communications to take place through your internet browser, allowing you to seamlessly join meetings without the need to download any additional software or plugins. Participants can:

  • Meet face-to-face with HD Video & Audio
  • Watch a presentation or webinar
  • Share your screen and PDF documents
  • Request Remote  Assistance

Receiving the invite

Once you have been invited to a video conference, you will receive an invite via email which mentions:

  • The title of the meeting
  • Notes from the organizer
  • Date and Time
  • Participants
  • The links from where you can join the meeting.


Joining the Web Conference

You will be able to join the conference from your desktop or laptop using Google Chrome and Firefox 48.0 or from your iOS or Android smartphone or tablet:

From Google Chrome

  1. Download the Google Chrome browser if you don’t already have it from here.
  2. Click JOIN FROM CHROME” in the invitation email.
  3. When joining a meeting for the first time, a pop-up will appear asking to allow access to your camera and microphone.

  1. Click Allow” to grant access or Block” if you prefer to simply watch and listen to the meeting.

If, however, you want to use more features of WebMeeting like Share your Screen” or Request Remote Control” you will be asked to install the 3CX WebMeeting Extension.

  1. Press “Install” and then “Add Extension”. A message will appear saying that the Extension was enabled.
  2. If you have used the extension again in a previous web meeting, make sure that you are using the updated one. 3CX will prompt a window clarifying if the Extension is up to date.

From Firefox

  1. Download the Firefox browser if you don’t already have it from here.
  2. Click JOIN FROM FIREFOX” in the invitation email.  
  3. When joining a meeting for the first time, a pop-up will appear asking to allow access to your camera and microphone.

  1. Click Share Selected Devices” to grant access.

Important: “Screen Sharing” and Remote Control” are not supported in Firefox.

From your iOS device

  1. Install the 3CX WebMeeting app. Download the app from the App Store.
  2. Once installed, click on JOIN FROM iOS” in the invitation email.
  3. A prompt will appear asking you to open the 3CX app, then click Log In”.
  4. From within your device you can interact in the web meeting, as shown below:

From an Android device

  1. Install the 3CX WebMeeting app from Google Play.
  2. Grant access to the App for Camera, Microphone and Gallery use.
  3. Open the invitation email on your device.
  4. Click on JOIN FROM ANDROID” in the invitation email.

Important: From the Android version you cannot interact, only participate (microphone and camera).


Smartphone - Choose the camera

Working from your smartphone or tablet, you may find that the back camera has been activated instead of the front camera. You can deactivate the back camera or set the front camera as your default by touching the screen; a Menu appears which offers an option to switch cameras.

Browser - Could not detect Webcam

In the unusual event where upon joining a 3CX WebMeeting your video is not working, please follow the below procedure in order to ensure your video is up and running again in no time. If your video is not working the below message will appear.

Another quick way to troubleshoot if your webcam is not working is to look at the preview on the bottom right of the screen. If you do not see your preview image there, then there is a problem with the webcam and you need to investigate. Also note that the camera icon is red.

The most common reason that causes your video to stop working is if another application is using your webcam. One way of quickly resolving this is by closing all video applications, and joining the meeting again.

If that’s not the issue then your browser may be blocking your webcam. Let’s have a look how we can fix this on Chrome.

  1. Press on the camera symbol on your browser’s address bar:

  1. A new window will open informing you that this page has blocked the camera and microphone:


  1. Select “Always allow..” and choose the Microphone and Camera to use.
  2. Press “Done” and refresh.
  3. Relaunch Chrome and go back to the invitation e-mail.
  4. Click the join button to join the meeting again. Make sure to “Allow” your camera to be used.

Tip: You can also do this from the “Google Settings ⇒ Advanced Settings ⇒ Content settings ⇒ Microphone and Camera.

      @Mukith, Good question. Join your meeting again and you will see an camera icon in the top right of your browsers address bar, Press this icon and you will see options to enable the cam and microphone.

    Hi I generally use my I pad or android device for collaboration sessions but I cannot enter a web conference using my IPAD. Even using Chrome it fails is there a fix for this and is there a similar issue with Android.

      @Mark. Thanks for your question. At the moment iOS does not support WebRTC, which is the core component for our web conferencing feature. Android devices on the other hand can be used using the Google chrome browser.

    Is there any alternative way for Windows desktop clients to connect? Many of our customers have locked-down desktops and do not have access to Chrome. The are currently unable to join 3CX web conferences.

    • Chrome is required, although soon you will be able to use Firefox as well.

    Is there a way to turn off “Receiving the invite” The reason is we dont need to send those out because we are currently talking with that person. What is happening is, we are getting outlook notifications left and right when we didn’t need to be notified in the first place.

Please contact your 3CX reseller/partner or distributor to open a ticket with our support team or you can even purchase a support contract so that you can contact support yourself then we can have look into this for you as it sounds like a configuration issue on your side.

    What about Internet Explorer support ?

    November 23, 2016 at 4:21 pm Reply
    • IE is phased out. I mean even Microsoft themselves don’t want you to use it. IE cannot be supported because it is ancient. EDGE cannot be supported because it does not support WebRTC.
