Polycom Legacy ( H.323 / SIP )

About

It is possible to connect to a Zoom video conference using your traditional H.323 / SIP equipment via a license called CRC which the contract already covers. See below for prerequisites and some tips for good use.

Note

A license per device connected simultaneously is needed.

Prerequisites

To connect to a Video Conference taking place on the Zoom platform from traditional SIP/H332 equipment, there are some requirements that need to be met:

1 - Have a compatible device List of compatible devices.

Important

Some places have reported that the Polycom QDX a model that is not on the list of compatible devices worked perfectly, so we suggest that you test your connection with your device even if it is not on the list of compatible devices.

2 - Have CRC licenses for each device simultaneously connected regardless of the video. (the contract already covers these licenses).

3 - Your equipment cannot be affiliated with any H.323/SIP gatekeeper during this implementation.

4 - Have an “Allow” rule in your firewall where the equipment is located, so that it can go out to the internet in case of using the connection option Dialing in and the list of zoom ips to get to your device if you use Calling Out.

Important

There is an Alias URL url that contains all ips of legacy rooms + the list of ips from Zoom that can be allowed in your firewall.

How to connect

There are two ways to connect your traditional device to a meeting that is taking place on the Zoom platform.

Security

As all videos on the Zoom platform are encrypted, it is very important to make sure that traditional equipment (SIP/H.323) is also configured to support encryption. See below how to set this up in your Polycom room.

1 - Access your Polycom equipment via the web interface.

2 - In the side menu click on the option Admin Settings> Security> Global Security and then on the option Encryption

3 - In Require AES Encryption fo Calls Select the option you want to apply. We recommend applying the Require for All Calls option or at least the When Available option.
