Got a call. No message. I've been getting a lot of calls like this, mostly from 415 area code.

I two calls one minute apart. left no message.

Got a call, no msg.

Received a call twice, back to back from this number;  I didn't answer and no message was left.
I'm also receiving alot of calls from different numbers and no messages left.  What bothers me is that I'm on the do not call list and it makes no difference!

Welcome to the wonderful world of VOIP, number spoofing, and offshore telemarketers.

My experience is that the Do Not Call List has become mostly moot.

I was reporting calls like the the Penna Do Not Call enforcement people, but all I got were lame letters about how hard it is to trace the things.

The cynic in me wonders how long the perpetrators of those calls would last if they were threatening politicians with harm.    Hours would be my uninformed guess.
