I finally got around to trying iCall and I like it. The sound quality isn't bad at all. It's only a little laggy, but that could be my computer, and it's free. I called my cell phone with it and it came up as a 646-465-7602. Apparently this is the number all iCall users use and we get an extension (Mine is 1220178 if you'd like to call me for whatever reason. Fair warning that I probably won't answer though.) to use. Two thumbs up for iCall until it fucks up or something. Then it's one up, one down, and one kind of hanging there loosely. Wait, THAT'S NOT A THUMB!
EDIT- I was wrong about the phone number being the one for all iCall users. Apparently all of
these are in use also. Apparently you can call any user with any of these and then entering the user's extension number. So I have phone numbers all over the country. That's kind of neat if you ask me.
