I'm with Rogers in Canada on a plan which allows free incoming calls, but only 150 minutes outgoing calls. When my wife wants to talk she calls me (from iPhone) but I usually let it ring a few times then I'll call her back.
Every once and a while though I'll pick up and let her talk (her calling me). When the conversation becomes somewhat lengthy I usually tell her "hang up and I'll call you back -it's free". A few times though she forgets to 'End Call' so when I try to call her back, she's still on the line, unknowingly.
This is scary, for should the line remain open for several hours (while phone in her purse), I'm looking to spend big bucks. It's not like a flip phone when you can just end the call by closing it.
Question: Is there some app that would 'kill' the call when idle? (no voice?) Is there some solution?
