Our solution can know if you are available to communicate. Stay connected even when outside of the office, set your status to lunch to let people know that you are not available or let the system integrate with your calendar to know when you are away automatically, miss a call and it will put you in an unavailable status until you come back. Check someones status before you contact them, send them a chat if you see they are on a call. Set routing rules to forward calls, send to voicemail or route based on the number calling.
