If we’re going to perform some pre-text phone calls we have a couple different options when it comes to the caller ID. We really only have 3 possible options which are: we do nothing to the phone number, we block our phone number, or we spoof our phone number.
Doing nothing to the caller ID will sometimes work depending on the area code you call from versus the area code that your client is located in. In my experiences, sometimes not blocking the number yields better results than blocking the number. I always feel like users are more suspicious when the caller ID says ‘blocked’or ‘unavailable’. Not only are they on heightened awareness, but I feel like they are less likely to even answer the phone thinking it’s most likely a telemarketer.
