Meeting Rooms

3CX supports these virtual meeting rooms, as set by your system administrator:

  • Private - For one-on-one meetings, ideal for support and customer service queues. Your personal extension’s or assigned queues’ Click to Meet URL can be used as a virtual Private room, enabling anyone to join from their browser as a participant via a:
    • Personal WebMeeting link - the system sends a notification e-mail or chat to the assigned extension.
    • Queue WebMeeting link - all member agents assigned to the queue receive a notification email or chat. Once a member agent clicks on the link and joins the WebMeeting, other members cannot join.
  • Shared - Organize group meetings, if the option “Requires you to connect to meeting first” is enabled by your PBX Administrator. Participants can join the meeting via the WebMeeting link:
    • Directly if the organizer has already joined.
    • After the organizer’s approval if the “Approve Participants” option is set by the PBX administrator for your extension to moderate participants.

📄 Note: If the “Approve Participants” option is set, kicking a participant out of a WebMeeting enables the organizer to keep them from rejoining.

Retrieve your Personalized Click2Meet URL

Your Click2Meet URL is set by the 3CX administrator and sent to you in your Welcome Email. It can be personalized to share via your email signature or on your website.

Important: We recommend using your personalized Click2Meet URL in “Private Rooms”.

Joining via a Click2Meet URL

To use Click2Meet, your administrator must set the “Requires you to connect to meeting first” option for your extension or queue for Click2Meet meeting requests to be delivered.

  2. An email and a chat message is sent to you, as a request by the participant to have an online meeting.
  3. Click on the link provided in the message to join the meeting or ignore.
