Line2 gives your iPhone a second phone number — a second phone line.

Line2 gives your iPhone a second phone number — a second phone line, complete with its own contacts list, voice mail, and so on. The company behind it, Toktumi (get it?), imagines that you’ll distribute the Line2 number to business contacts, and your regular iPhone number to friends and family. Your second line can be an 800 number, if you wish, or you can transfer an existing number.
