I answered and got a failing beep that hung up the phone.  
I did not hear anyone on the other end.  
I believe this number has called me before with the same result.

If this is AMVETS they are NOT bad.  They do not ask for Money, just want to know if you have some clothes you would like to donate.  They are very polite, if you have clothes they will pickup at your house, you just leave outside the day they say they will be there.  I've done this on numberous occasions with no issues.  I've been getting a lot of calls lately and have not picked up (new to caller ID, don;t laugh) now that I know I will take to call since I have been waiting for their next call since I have items to donate.

It's AMVETS

I have received numerous calls from them as well don't pick up
