[How to deal with the call park "black hole"?]

My receptionist parks a call, and there is no indication that there is a parked call...

 

Either:

She misdials where she wanted it parked

Forgot to announce on the PA that a caller is parked

The person receiving the call doesn't pick up

 

So here the caller hangs out in limbo, enjoying the hold music until they hang up and try again.

 

How are folks dealing with this 'feature'? Just not using it? Any workarounds?

 

Help!

 

Thanks
