I received call about 9am PDT from this number. I'm with Sprint & doubt it has any difference which company one has service with. I didn't answer & no message was left. I'm blocking this number. BTW my number is actually a 661 area code. The calls could originate from anywhere in the world and be "spoofed" Caller ID to show Los Angeles phone number.

got the same thing

This was a robocall to my cell phone. They were selling some vacation package or time share, but the voice was a recording that would not respond to my questions.

Its always quiet and then hangs up. but very persistent.. have had at least 3 attempts in last week

This outfit called my cell phone early in the morning a couple of days ago, but hung up before I could answer.

This same number rang on my computer's fax line repeatedly for over 30 minutes at well after 10pm tonight. My fax line kept picking up and doing the beep+static noise, but the incoming call would immediately disconnect and dial in again! As I write, it's still continuing. I'm gonna figure out a way to tell my computer to take the "phone" off the "hook".

This is totally annoying!
