This would be very useful to any place that has a group of people to answer phones. For example we have 5 people that can answer anytime someone calls our office. 2 of those people only do it if others are gone from work, so it would be nice for it to not ring their phones unless they are filling in for the others. I was thinking maybe there would be a way to create a button or something to where they could mute/hop out of the call group so they dont have to hear their phones ringing all day. Also so we do not have to keep going in and out editing the call group everytime they need back in it.
