The cell phone walkie talkie is also known as push to talk (PTT). This means that you need only push one button to have instant access to the other person. The phone doesn't have to ring for the other person; he or she will hear your voice immediately. Another benefit of the cell phone walkie talkie is that you can talk to groups of people at one time. You simply talk, everyone else listens, and then it is someone else's turn to talk. If considering this use of a cell phone walkie talkie, make sure that everyone you need to talk to has the walkie talkie feature on his or her phone.
