Thanks for your feedback.
What is the Maximum Number of Participants in a Webex Session or Call?
Feedback?The In-meeting participant and meeting audio capacity will vary depending on which service you are using.
ANSWER
- If the session type in Site Admin has a number after the session (Example: Webex Meetings 25), then the number indicates the attendee capacity. If this number is exceeded, additional participants may not be allowed to attend the meeting, or overage charges will apply.
- When the participant audio capacity has been reached, attendees will hear the following error when joining the teleconference: 'System error 4004: The conference you are attempting to join is full.'
- If an attendee does not use the attendee ID to join the audio conference of a Webex meeting, the attendee will be counted as two participants.
- If a meeting scheduled as an audio-only conference is escalated to an online Webex meeting, the number of participants can join the online meeting is limited to 25. For details, see: WBX79050 - Error: Meeting you are trying to join is limited to 25 participants and no more participants can join the meeting'
Overage charges vary depending on your service model. The number of Users/Ports available will be based on your original service agreement.
The maximum number of participants in each service are as follows:*Participant includes the host, presenters, and panelists.
In-meeting video device:
| Video Device Capacity | ||
| Service | Video Platform 1 | Video Platform 2 |
| Webex Meetings | 25 | 200 |
| Webex Events (Classic) | NA | 200 (Host / Presenter / Panelist only) |
| Webex Webinars | NA | 200 (Host / Presenter / Panelist only) |
| Webex Webcast Mode | NA | 200 (Host / Presenter / Panelist only) |
Note:
- Video device capacity counts towards the in-meeting participant cap. For example, if your Webex Meetings site is configured to allow 1,000 participants and 200 video devices to join, 800 participants can join via PC/Mobile/Teleconference.
- In Webex versions 41.3 and earlier sites, only the first 1000 Event participants can receive participant videos. (Example: when turning on a webcam (or a video device) as a panelist, only the first 1000 participants can view it.). This applies to Cisco Webex Events, which have up to 3,000 participants. This condition does not apply to Webex Webinars (formerly Webex Events (New)) Webex versions 41.4 and older releases as the 1000 participants limit has been removed.
- The grid view can show a maximum of 6 simultaneous endpoint video streams and 25 video streams. This limitation only applies to Video Platform 1.
