Who called from 2024029999

Received call from this number, sounded like a 40-50 year old woman, asking when my boss would be back in her office.  Used her full name, and then asked for her government email address.  I told her I couldnt give that out over the phone.  She then got very angry, said something about secret information, and then slammed the phone down.  Called back about five minutes later, refused to ID herself, said what she thought was the email address, and then bitched me out before slamming the phone again.  Callbacks only got that same fast busy signal.  
Sounds like a phishing attempt

This number called our house and the lady, sounded to be about 45-55 years old, said she was a person from the Dept. of Housing and Urban Development.  She was looking for someone and she used names that would fit the home owners initials, gave a number to use when calling back, and when I called the number back she said she misdialed.  Sounded like a weird explanation.  The number in the message did not match the number she originally called from to record the message (caller ID).  I have contacted a lawyer to get advice, and I am a member of an identity theft service so I know what steps to take for protection - it is NOT Life Lock services so hopefully I can deal with the problem if one arises.  Hopefully, it is a legitimate call, but I have my doubts because there was no reason for this individual to call our number.

I got a call from this number and it was Dept. of Housing and Urban Development's personnel office, but it appeared as disconnected when I tried to return the call.

Same thing with me.  I got a call today in Houston on my business phone on 11-23-2010 at 2:51pm from 202-402-9999.  I didn't get to it, because I was busy doing work.  Yet, I try to call it back and it is disconnected.

I recieved a call from this number. It appeared on my caller ID. Iddint recognize the number so I didnt answer. NO message was left. I tried to call and got the same weird signal.
