A neat trick for those that want to mask their caller ID to say “Private Caller” or “Unknown” is to dial *67 before the rest of the phone number. It works on cell phones, too. However, your call is still traceable for law enforcement, you can perhaps surprise a friend or client to see if they are screening your calls in particular. Companies that use a VoIP phone system can adjust their caller ID for each business phone number. Nextiva supports up to 15 characters, but note that telephone networks may not necessarily display it the same. Ideally, you would want to choose your name or your company’s name.
