Alert When User Presence Changes to Available

It would be helpful if we could set some kind of presence alert that notified us when a user becomes available. If we are trying to connect with another team member that is on the phone, we have to constantly check back to see if they're still on the phone. It would be nice if there was a notification you could enable to alert when they get off the phone, so you don't have to keep checking your Ring Central application to see if they're available.
