SIP/H.323 device call-out from Zoom Rooms

This post was most recently updated on July 28th, 2022

You can make calls directly to a SIP/H.323 device using Zoom Rooms via SIP/H.323. Also, in the Zoom Room controller there is an option to add SIP/H.323 devices that will be added to the contacts list when they are added in the Zoom website portal. Unlike other video conferencing solutions, Zoom Rooms allows users to call-out at the same time to one SIP/H.323 device at a time. A license will be needed for each SIP/H.323 device in the meeting, in order for the account to be able to run meetings with multiple SIP/H.323 devices.

Note: Room controllers that run on iOS or Android are covered by this set of instructions.
