Last number called on landline

[Pam+1]

What happens if you don't disconnect a call you made on your landline. I didn't realise that I hadn't replaced the reciever properly until a few hours later

I believe  when the person you called hangs up you're also disconnected automatically.

So I shouldn't get charged then 

[Mark39]

If I'm right- no. You might pay for a minute or so extra, as I believe there's a slight delay before the system detects that the person you called has hung up. Your itemised bill will show you what you've been charged for,the call after z day or so.
