I have a user I want to add as a team-call member but it is not letting me. It give the error "If OK isn't enabled, you've picked one or more contacts who can't participate in this activity"
I have 3 users - 2 are voice enabled and the other isn't. The user who isn't voice enabled is one I can add, but I can't add the voice enabled user.
What is causing this issue? Any ideas?
