Well, fortunately that's your work phone, so you're not paying for the extra minutes. Sending them to voice mail is a good option, except that then you still have to wade through them to find your genuine voice messages. The one from Verizon is probably about an account that used to have the same phone number. I've gotten quite a few of those. I once got a text message from a young man asking his mom for a loan to get him and his wife through the weekend -- his mother had apparently gotten a new phone and let the number on the old one lapse, and didn't give out her new number to her son! (Of course, considering the kind of texts he was sending her, I can understand why.)
My cheesy work cell phone doesn'tIt's a "fake Blackberry" type phone. I get way too many telemarketing and junk phone calls on my work cell phone and I have never given the number out to anyone. The most frequent one is from Verizon calling about a recent bill. My work cell phone is on AT&T service, not Verizon. Then there are the messages left in Spanish about winning a vacation getaway. If I don't recognize a phone number, it's sent directly to voicemail.
