Cisco Room Kit Standalone unable to join webex meeting

[sandysp4u]

Hello Friends, 

I recently got a Cisco room kit and I am trying to join a Webex meeting with it but it is not working it I tried both ways by meeting id and by dialing the video address. The room kit is in standalone mode and is not registered to any services. 

any help, please?

A stand-alone endpoint is only capable of a direct H.323 or SIP call; neither of which are compatible with NAT. Give the endpoint a public IP and try again. Or use a direct cloud registration to Webex Control Hub (license required) which would allow it to traverse the firewall/NAT.
