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

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.

  • 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]

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.
