Nowadays more and more companies have employees working remotely from their home or even in other offices around the world. Travelling for meetings costs time and money which could be better spent elsewhere. With the 3CX clients for Windows and Mac you can hold online web meetings, collaborate with colleagues, or present to prospective clients. The meeting can take place in any open standards browser. 3CX WebMeeting uses WebRTC technology, so you and your participants don’t have to download and install any additional software or plugins. WebMeeting must be enabled by your administrator for your extension. There are two ways to start a 3CX WebMeeting.

Important: In order to host a 3CX WebMeeting with your iOS device you will have to download the 3CX WebMeeting application from the AppStore. This feature is not available for the 3CX client for Android.

Start a 3CX WebMeeting immediately

  1. Click on the Start a 3CX WebMeeting Now  option which appears in your client’s dashboard. This automatically opens up your browser.

  1. If this is the first time you are using the web conferencing feature then you will receive the above message. Allow the use of the camera and microphone in order to proceed.

  1. From within your browser you can start inviting participants. You can do this in the following ways:
  • Click the  icon.
  • Press the “plus” icon next to Attendees
  1. For these 2 methods, a window will appear asking you to add participants by providing the name and email. Then click on the Add button. Once all participants have been added to the list click on the OK button. An email will be automatically sent to all participants with the link to enter the web meeting.

Additionally, you can click on the  icon or the Link next to the “Meeting Info” in the top right corner of your browser and the meeting link will be automatically copied to your clipboard. You can then send the link to other participants.

In the iOS client, the interface is quite similar with the same options and reactions.

The meeting link URL can be found in the Meeting info section. You can only start a WebMeeting immediately.

Schedule a 3CX WebMeeting

  1. From the 3CX client for Windows or Mac main screen, click the “Conference”  button, and select Create 3CX WebMeeting.”
  2. You can add participants in three ways:
  • Enter an external participant’s name and email in the respective fields and click . Repeat the process to add additional participants.
  • “Add from phonebook” button. Select the contacts you wish to invite and click “OK” on Windows, or “Back” on a Mac.
  • “Import” and select a .csv file saved on your computer. Click “Open.” Note: The .csv must be in the following format:
  1. When all participants are added, click “Next.” 
  2. On the Meeting Info screen, add the Subject of the web meeting and Notes to participants. These notes will be sent to the participants in the invitation email.
  3. Schedule when the meeting will take place, along with the meeting’s duration. You can now press Schedule.

Advanced Settings

From the Advanced Settings  for Windows, Options in Mac, or Settings in iOS from within the meeting interface,  you can set whether you want your participants to join the meeting before you and which startup options will be enabled for them. Specifically:

  1. Connectivity: If the checkbox is not ticked then the participants can join the meeting even though you are not yet connected.
  2. Organizer startup options: From here you can set which features will be enabled for the organizer from the startup. The choices are between Audio, Video and Chat.
  3. Participants startup options: From here you can set which features will be enabled for the participant from the startup. The choices are between Audio, Video and Chat.
  4. Click “Schedule” to schedule the meeting or “Start now” to enter the meeting right away. A new tab will open in your browser and you will automatically be logged in to your web meeting.The organizer and the invitees will receive emails with the meeting details.

    What can cause this issue both the presenter and the attendee “Click here to Join” / starts the meetings and gets: Connection to the server failed?

      @Jason, Thanks for the question. If it is an Integrated version with PBX 12.5. Then there is no default MCU selected. Hence the error message. In this case please open a support ticket and provide us with the name you want the portal to be so we can set one for you.

    Not able to see “Start a 3CX WebMeeting Now” option. I activated web meeting on 3CX, version 14, SP2 PBX.

    • @Alay Amin – Can you check the portal settings? You would need to open a support ticket on this. Do you see the webmeeting button on the phone in the main screen?
      If you click on it what happens?

      @Bart, thanks for the question. If you are referring to the WebRTC page that a user sees when they make a WebRTC call into the system then this can be changed but we do not have any instructions available to offer you on how to do this. If you have knowledge of the inspect element feature within your browser and knowledge of IIS or the Abyss webserver then you can find which element needs to be modified in order change the background picture.

      @David, If you are referring to the 3CX WebMeeting feature that is integrated into 3CX Phone System then with a 3CX Pro License you can have up to 25 participants taking part in web meetings at any one time. You can though license more by purchasing a web meeting license. For this though please contact

    Is there any video demonstration of running a 3CX meeting with multiple participants. We are specifically looking at sharing the Presenter’s camera/applications with participants BUT not sharing partucupant’s with wach other – i.e. a many to one conference. We also need to capture the video (presenter’s view of all participants) for compliance purposes. We already are running multiple 3CX PABX’s at or site and our vendor recommended looking at this product for upcoming requirements.
