I picked up the phone, said Hello, and waited for an answer.
The line sounded dead for a couple of seconds and then I could hear someone picked up because I could hear noise in the background.  They didn't say anything and hanged up.  This is the 3rd time they call this month, only this is the first time I pick up the phone.  Other times my answering machine picked up and they did not leave a message.
The background noise sounded like it was a call center.  Someone PLEASE STOP these people from wasting our time.

I keep getting calls from this number with caller id Brivia comm LLC and asked to spell my company name.  Any idea who this company is?

Just got a call from 415-874-5590.....line dead when I picked up.

i also got a call from this phone number. When i picked up the phone, all i heard was bunch of people talking in the background, i think it was a call center. i am going to report them to my telephone company and have them block this number.

I also got  caller ID 415-874-5590 and there is no one answer the call. Any one can help to stop this?
