Help Hang up on other call on call waiting?

[Mike20878]

There is a "switch calls" button when I answer a call on call waiting, but is there any way to switch to the previous call, hang up, and come back to the new call? I tested it today and I hung up on everybody.

I've had the same problem. Has also locked up the phone on a number of occasions.
