This post was most recently updated on August 1st, 2022

In the event that you are joining the meeting from an H.323 or SIP device, you may be able to change your video layout. Also, a video layout can be configured as the default in the H.323/SIP Configuration and can be changed by changing the dial string or by changing the video layout.

Note: Video and content can only be sent and received using H.323/SIP devices, and can only be sent or received if they are either 720p or 1080p.

How to select a video layout in a dial string

If you do not select a different option in your H.323/SIP configuration, the default layout of a meeting is Gallery View. Whenever you enter a meeting, you have the option of changing the video layout as follows:

As an example, if you are using an H.323 device, you will need to enter ##11 at the end of the dial string (#11 if you have entered a meeting password).

  • Format: [IP Address]##[Meeting ID]#[Password]#11

For SIP devices, enter ..11 after the Meeting ID (.11 if a meeting password is entered)

  • Format: [Meeting ID].[Password].11@[IP Address]

The next video layout option will be selected as soon as you enter 11 in the dial string. In the H.323/SIP configuration, if Gallery View is selected as the video layout, then entering 11 will toggle the video layout to Full Screen, and if you choose 1111, you will toggle the video layout to Thumbnail View. In the event that you have selected a different default, the video layout will move from Gallery to Full Screen, then Thumbnail view, according to the order of the video layouts.

Video layouts available for SIP/H.323

Gallery View

It is possible to view up to 25 participants at the same time in gallery view. As a result, the grid size will either be 2×2, 3×3, 4×4, or 5×5 depending on the number of participants. There is an option to activate the menu if there are more than 25 participants, and then there is an option to go through additional screens by pressing 4 or 6.

Full Screen

Displaying the speaker in full screen mode displays the speaker in full screen mode.

Thumbnail View

Thumbnail views mimic the active speaker view of the Zoom desktop client, and are designed to mimic its appearance. With this video layout, we will be displaying a large video window with text near the bottom of the video that will include the current active speaker, as well as thumbnails of up to five other recently active participants.
