Note: H.323/SIP devices can only send and receive video up to 720p, as well as send and receive content up to 1080p.

Prerequisites for changing the video layout on a SIP/H.323 device

How to select a video layout in a dial string

The default layout of a meeting is Gallery View, unless you select a different option in your H.323/SIP Configuration. To change the video layout when entering the meeting, you can do the following:

For H.323 devices, enter ##11 at the end of your dial string (#11 if a meeting password has been entered.

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

Entering 11 in the dial string will move to the next video layout option. If you have Gallery View set as the video layout in the H.323/SIP Configuration, entering 11 will toggle to Full Screen and 1111 will toggle to Thumbnail view. If you have a different default selected, it will move to the next video layout, in the order of Gallery, Full Screen, then Thumbnail view. 

See H.323/SIP Room Connector Dial Strings for more information.
