I have a phone that has call blocking. I can block up to 250 numbers. That's almost filled up after 2 years. These calls from solicitors are akin to barking dogs and screaming children: All are totally unnecessary.
Just so you know......they are still calling weekly, no message and still unknown, however, the V# has been different with each call. Today I called back and surprise, surprise, surprise. Number is no longer in service. Guess I'll just have to buy a call blocker or disc. my phone. My phone server has a max of 30 call blocks. I can use that in a couple of days.
