I have been getting calls from this same number. Did some research on it. Turns out these people posed as different business. In other words, they are scammers. Don't give your information. I know they heard my female voice when I finally answered and they asked for "Steve". My cell is registered on the Do Not Call List. I will be filing a formal complaint. I suggest everyone do the same.

I received a call from this # on cell when I answered they hung up.  I called the same # within seconds and got a recording indicating this number was disconnected

Here is some info about these callers:
Phone Number: 5624388433
Owner Name: M Drace
Most Current Address: 39 61st Pl Long Beach, CA 90803
Area: SEAL BEACH, CA (California)
Phone Company: VERIZON CALIFORNIA INC - CA (GTE)
Switch: LNBHCAXT43K

Called twice.  First time, no message; second time I answered.  Caller hung up.  Number is listed by Mr. Number as belonging to Marianne Butler.  Because I have a friend with the same last name who lives in that area, I thought the call was legitimate.  That number is now blocked.

Called here asking for Mr or Mrs (our last name) daughter told them they had the wrong number they just hung up

Yeah, this is a telemarketer.  Calls and leaves no messages.

It's an illegal sales call if you're listed in the "Do Not Call" registry. They're trying to get you to install leased solar equipment on your house.

I have receive numeros calls fom this number and when i tried to call back is said disconected WTF? sounds like a scam and this area code is local to where I work

Tonight the call was from a solar company who makes you think they are the electric company who want to save you money. She asked for the "homeowner." I said the following and boy did she hang up quickly. "Excuse me, do I have your permission to record this call to use as evidence for the FCC for the violation of the National Do Not Call List?" She said, "No, but that's a pretty good one Lady!"  I LOL'ed!!!

Called 11/20/2013 at 1:40 pm.  No message left.  This was an unsolicited, unwanted, illegal telemarketing call.  I added the number to my Pro Call Blocker (overpriced, difficult to program, but it works), so they will never be able to call me again from that number.

As usual, I filed a formal online complaint with the FCC.  I ALWAYS DO THIS.  It may not do any good, but if you report the illegal activity enough (like if hundreds of thousands of people report), then MAYBE our idiot government can figure out something to stop these criminals.  Probably not, but I report them anyway.

received my first call from this number today at 3:45

Received a call from this organization wanting to lower my electrical bills at a given address. Sorry I don't live at that location. He apologized and said good bye.

Telemarketer

Is just a telemarketer about debt consolation.  They bug all the time.  

No msg left on ans machine. Redialed and received auto network msg that "We're sorry but your call cannot be completed as dialed."
Obvious scammers.
Our number is on the federal Do Not Call list.

Received a  call from this number asking for one of my family members. I didn't want to question them because I didn't want them to continue calling so I just said wrong number. Anyways, I wonder who they were.
