My Man Cave gets horrid cell phone reception. There's always the option of adding VoIP through Verizon, but it dawned on me that I could get an app on my iPhone that I could use for outbound calls while at home. I'm always using the wireless network at home anyway, so I didn't see any reason why this wouldn't work.

I looked at the App Store and found one decent option, iCall, but some of the mechanics to get it to work may include calling a high priced toll number to get it to work. I find that far more insulting than just charging for the app upfront.

Anyone ever used VoIP over your iPhone? What do you use? Is the sound quality as good as a real call?
