Calls in the game

Where is possible shutdown calls (only calls) in settings?

Every time one of my teammates makes a “call” my character is uncontrollable for about 0.5 seconds. I will remain motionless. Where can it be turned off in the settings?

And another thing, why is this forum the only option for support? Is this game no longer supported? All links refer to the forum. Forum will never replace support! Is this game over yet?
