In our could is it possible to disable a particular account for a particular time?
There really is not a functionality like what you describe at this time. If you want to remove someone from the subscription, you need to delete them and then re-invite them when you want them back. This process creates a new user account/member and the individual will receive a new number.
I would encourage you to open this as a feature request by using the Idea content type (How to Create an Idea or Feature Request) and open it to the community for voting. Ideas are how we get feature requests in front of the Product team here at Lifesize.
If you would also like to see this functionality, please vote on the idea found here: Cloud Account user Management
I already create this in idea as the name of Cloud Account user Management.
Your idea is the one that I referenced in my post, sir .
Thank you Michael for refereed my post
