Can anyone tell me how to deactive/turn off the call waiting feature on my iPhone 5? I find it really annoying to be interrupted by a call when I am talking to someone else. I would prefer the second caller to get a busy signal, or transfer directly to voicemail. Even better would be a special message greeting that informs the second caller that I am speaking to someone else now and to either leave a voicemail, or call back in a few minutes......
Any help would be appreciated.
