MaxAgent Inbound Call Waiting Alert

I have a small shop, and users go on unavailable but still are on call if the call volume spikes. Such users have to devote desktop space to have a MaxAgent window displayed, and the have to cast eyes on the same.

Our last phone system had a setting where after calls are waiting 60 seconds, anyone signed in but unavailable got a popup notifying them of the need to take calls. I cannot describe how disappointed I am with this gap.
