Hi gorbva and welcome to the Forum!

If you search the forum (which always is a good idea) you will find that similar requests have already been made. Better to add a vote on those, instead of starting a new topic.

Also, please consider a more descriptive name for the topic when you create one. "vMix Calls" does not say very much about what you are after. A good name helps us users to decide if it's worth reading or not.

Thanks.
