Good morning, hoping that you are wonderful.

I have a polycom realpresence group 300 team, this team used it for video conferences with Zoom.
From my Polycom equipment I set the following IPS:

149.137.68.253 (Mexico)
162.255.37.11 (US West)
162.255.36.11 (US East)

Followed by the Meeting ID: and Passcode.

I connect to the meeting without problems, the problem comes here, after a few seconds, the participants start to freeze.

Note: The polycom team has already been updated and I still have the same problem.

Greetings and thank you very much.

@AlfredoEndemol I suggest following this article for whitelisting the appropriate IP ranges to ensure there are no issues. 
Network-Firewall-Settings-for-CRC 

 

If you have any issues after configuring your network/firewall correctly, I strongly suggest reaching out to the Zoom support team as they would better assist.
