Firewall ports to open Some MTR can join zoom meeting via direct guest join

[Bat_Man]

Hello community,

I have Cisco devices in a Microsoft Teams environment, and these devices are running in Microsoft Teams Room mode.  I want these devices to be able to join Zoom meetings using Microsoft's direct guest join feature.  What firewall ports do I need to open to make this happens?

Thanks for the response. Unfortunately, there seems to be nothing there that tell me what ports someone on an MS Teams Tenant needs to open on their firewall in order to join zoom meeting.
