Terry gets a lot of phone calls from local numbers he doesn't recognize. Leo says that's called "Neighbor Spoofing" and it's designed to get him to answer the phone because the caller ID shows a local number. If it's important, they'll leave a message.
Can he respond to text messages with VOIP? Leo says he can partially. If he's using an app like WhatsApp, he can as long as the other side uses it. But if it's a "text subscribe to [enter number here]." It won't. VOIP doesn't support that.
