Caller ID Sunnyvale CA. Hangs up and leaves no message. Call preceded by 'Unavailable' with no number ID an presumably to validate your phone number and test blocking. Typical scammer/political solicitation/harassment tactic.

Rings 3 times, and hangs up; no message.  I blocked my CID and called it back, some guy answers.  I decided not to say anything and just waited in silence... he said hello a few times, and hung up,...  I am not sure, I feel somewhat satisfied that I got to reverse the roles here...  taste his own medicine.

Calling numbers back doesn't help matters, in fact can make them worse. Its bad because the numbers are spoofed as a ROT. You could be calling some innocent persons number or a innocent business that had nothing to do with the calls. While we understand that is is a frustrating thing, its just a bad idea.

Consider buying a call blocking device or phone. Many are around $50.00 and can block up to 1500 numbers. If its a cell phone, some already have call blocking, if not, there are free apps on the web that will work for some. You can google this. If u have a smart phone, there is a free app called call control. Iphones appear to have apps also.

the do not call complaint list is a joke..I file may a complaint on some of these callers and  a year later they still call..it even says on the complaint form that they just take information..u

The DNCR is not a call blocker.

Put the blame where it really lay's, with the criminals and illegal telemarketers.
The DNC works just fine. It is for telemarketers only and honest business does indeed abide by it. It is the criminals (which includes illegal telemarketers), frauds and scammers that do not. However, the Fed. DNC does not cover some survey's, Political or Charities.  You would need to check your states DNC laws to see if these are under your states DNC laws.  The fact remains that they are not automatic call blockers though and can not protect you from the calls that are criminal, illegal or fraudulent.

Do consider maybe getting a call blocking device or phone..  You can google them and many are around $50.00 or so. And here are the links to read and understand what the DNC's are, what they do and what they do not.

It is incredible that people seem to expect these calls to magically disappear. On more than one occasion I have asked people here, "Why would a bogus operation follow the law?".

Or one could say, when did a criminal ever obey the law? Good point that is!

You and I both know that life isn't that simple.

How true that is! If it only was, we would all be blessed!

I received a call - they didn't leave a message, so I called back - hit *67 first so they don't know it's me---how sneaky! LOL! Anyways, it's some faux fund raising company raising fund for police and their families.  Sorry police - you give me tickets so I'm not going to contribute.  But lets just say for a moment its a charity I would consider.  I asked the well-scripted salesman what percentage of the donated cash goes to the policeman and their families, and what percentage goes to admin costs - telemarketeers, office staff, and other employees of this foney-baloney non profit.  They said they keep 90%.  So for every $100 you donate, only $10 goes to the cause.  The balance ends up in their hot little hands.  I always ask telemarketeers the percentage.  If they haven't hung up with me by then, I ask them if they thought that was even reasonably fair.  Of course not!  How can you justify asking for donations for someone/something, and keep 90% of the funds?  Scammers!!!!

Got three calls withing minutes from this number - all were "missed calls" (left no message). Will block

They called me at dinnertime, 6:20 tonight.  Left no message, I didn;t recognize so I didn't answer.  Llike they say, the do not cal.gov is a joke.

This number called and said they were collecting funds for disabled police. Scammers.

Left no message. Just another scam call.

Hung up with no message when answering machine picked up.

Called and left no message.  No listing other than Sunnyvale area code, Level 3 VOIP line.  Appears to be some form of financial scammer from previous comments.  I believe they have called before.

My caller ID only said  Sunnyvale, CA - it was automatically blocked by PhoneTray, a call blocking software package from Traysoft.com, which works with an inexpensive modem and connects to a database of known scammers and fraudster telemarketers. *standard disclaimer* I am not an employee of Traysoft.com, just a very satisfied customer. Check them out!!

Some guy called me asking me to donate money to some cause. I had no idea what he was talking about

Left no message. They had called me on Nov. 6. They are just a scam. They've been blocked, so the phone only rings once.
