Which Proctoring Software is easy to Integrate with OpenEdx?

Hi,
One of my client is looking the Proctoring Software and Virtual classroom with Whitebaord as integrated part of the OpenEdx based LMS.

What are the tested and verified 3rd party Softwares?

Thanks

My suggestion is to go with https://github.com/edx/edx-proctoring/blob/master/README.rst
And
Bigbluebutton for virtual classroom and whiteboard solution

Thanks for Virtual classroom we are using Jitsi at this moment. Any suggestions for Proctoring Sw?
