Join a Meeting via PSTN

You can dial into a Cymbus meeting using PSTN. With this method, you use a phone to listen and speak during the meeting. No video or screenshare available. Other members only see your phone number, not your name. A part of your phone number will be displayed with * to protect your privacy.

You can join the same meeting concurrently using the Cymbus app, PSTN, and a desktop browser. Let's say you are driving and stuck in a traffic. You can dial into a meeting using PSTN, then later join the same meeting using the Cymbus app when you get to the office. This way, you won't miss any part of the meeting.

Join as a Participant or a Guest

  1. On the meeting invite, locate the following. If your meeting invite does not list a dial-in number, dial-in is not available for this meeting.

    • A Meeting ID,

    • A dial-in phone number for your area, and

    • A passcode if required by the host.

  2. Use your native dialer on a mobile phone to call the dial-in number for your area.

  3. Follow the audio prompt to enter the meeting ID, followed by #.

  4. If asked, enter * followed by #.

  5. Enter the 6-digit passcode if enabled by the host. You will be either allowed in the meeting or placed in a waiting room.

Muted Upon Joining

You are muted when you enter the meeting. Dial the star code *6 to unmute and speak. After dialing the star code to unmute yourself, you can use the mute icon on your native dialer to control your mute status. However, if you later hear "You have been muted," you must dial the star code again to unmute yourself. In this case, tapping on the mute icon on native dialer does not unmute because you have been muted by the host.

Join as a Meeting Host

To join a meeting via PSTN as a host, you need a host key.

A 5-digit host key is visible only in the meeting invite sent to the host. When you click Copy Invite, the host key is excluded for a security reason. If you are copying the invite for yourself, manually add the host key.

If a wrong host key is entered for a few times, you will join the meeting as a participant. In this case, you are required to enter the passcode if you enabled it for this meeting.

  1. In the Cymbus app, go to Icon for App Video Tab Meetings, and select the meeting you want to join, and locate the following in the invite. If your meeting invite does not list a dial-in number, dial-in is not available for this meeting.

    • A Meeting ID,

    • A phone number for your area, and

    • A host key.

  2. Use your native dialer on a mobile phone to call the dial-in number for your area.

  3. Follow the audio prompt to enter the meeting ID, followed by #.

  4. Enter the 5-digit host key followed by #.

    You are muted when you enter the meeting. Once you are in the meeting, you can dial star codes for these actions.

    • *6 to unmute yourself. After that, you can use the mute icon on your native dialer to control your mute status.

    • *7 to end a meeting for all (available to the host only)

If a waiting room is enabled for a meeting, all participants automatically enter the meeting once you join using PSTN with the host key. Note that you have no ability to control mute statuses of other participants or remove participants.
