Using 1080p video for SIP/H.323 devices

Organizations can utilize 1080p with their SIP/H.323 room systems when joining meetings and webinars. However, unlike joining via the Zoom Workplace desktop or mobile client, there are additional requirements and configurations needed to use Full HD with room systems.

Requirements for using 1080p with SIP/H.323 devices

• A Pro, Business, Enterprise, or Education account
• Owner, Admin, or “H.323/SIP room connector” Role-based privileges
• A Zoom account with a Cloud Room Connector license
• A provisioned SIP/H.323 room
• Full HD (1080P) enabled at the account level

Note: This feature needs to be enabled by Zoom.

In addition to the above requirements, the following in-meeting requirements are necessary

• 1080p video feeds
  • For 1080p video to be displayed, the video being sent must be from a 1080p camera
  • Shared content must be shared at a resolution and window size of at least 1920x1080

Limitations for using 1080p with SIP/H.323 devices

• If the device's bandwidth falls below 3 Mb/s for upload and 6 Mb/s for download, the video feed will be negotiated to a lower resolution.

How to enable 1080p for SIP/H.323 room systems

1. Sign in to the Zoom web portal.
2. In the navigation panel, click Room Management, then click Cisco/Polycom Rooms.
3. Click Account Settings.
4. Click the Meeting tab.
5. Under Common, enable Enable 1080P.

How to configure managed rooms to use 1080P

How to join meetings with 1080p from unmanaged rooms

To join meetings with 1080p from unmanaged devices, the DTMF command 309 for 1080p video support, and the DTMF command 100002 for High-quality Content Sharing need to be added to dialstrings when joining meetings. The following examples are dial strings for joining meetings with 1080p (using DTMF code 309100002).
