How can i host a meeting with cloud room connector via Polycom Group 500?

I have purchased both zoom rooms and cloud room connectors. I have installed the API. Since group 500 doesn't natively support zoom, i still get the same screen as before. I have tried to manually call personal meeting ID, i have tried to use hash tag and add the meeting key etc. but nothing works. 

When i check room management > Cisco/Polycom Rooms my status is connected and IP address is local IP. Provision status is Provisioned and SIP status is Registered(zoom). Everything seems to be ok.

I can not start a meeting neither i can receive a call. Only thing I haven't set up yet is the calendar because we are using yandex and it is not on the list. 

Do you have any documentation or suggestion that i can follow?

Thank you.
