First, I would like to mention its not really recommended to have the room kit configured with a public IP, and NAT is not necessary. A Room kit registered to webex cloud will have full functionality with an internal address. If external / B2B calling is needed, you should look into an expressway setup, and that is where the public IP should reside.

For your question though, as Webex is in the public cloud, both scenarios will have the signal / media connect to the webex cloud. For the NAT'ed device, as long as your SIP Inspection is running properly, it should be handled the same.

Please review this doc for Network Traffic and IP ranges for webex -https://help.webex.com/en-us/WBX264/How-Do-I-Allow-Webex-Meetings-Traffic-on-My-Network
