Zoom Conferencing - Calling a Hardware Codec

Although Zoom is a software-based conferencing application, it is possible to connect to traditional hardware-based H.323 codecs via Zoom's "Cloud Room Connector" gateway. Here's how:

Start your Zoom meeting
from the meeting toolbar, choose "Participants" and then use the "Invite" button
From the pop-up window, choose the tab marked "Room System"
Choose the second tab, "Call Out"

In the field provided, enter the IP address of the device you're calling.
Hit "Call"

If you know you'll be connecting to the address on a regular basis, you can request to have it added to the Zoom Address Book, accessed via the pull-down menu next to the IP entry field. To request an addition to the address book, please submit an IT Support Ticket.

It works the other way around, as well; you can join a Zoom meeting by calling from a hardware codec.

Here's how;

find the Meeting ID number for your meeting (it should appear next to the meeting name in the "Meetings" tab on your account page and will be 9 to 11 characters in length)
On the hardware codec, dial the IP address of Zoom's "Cloud Room Connector" (ex: 162.255.37.11)
when you get to the Room Connector welcome screen, enter the Zoom Meeting ID number.

NOTE: The invitation emails generated by Zoom will include information on how to join via codec or telephone. Include all details in your invitation to give guests as many options as possible.
