Have received several calls from this number.  I've been awakened from a nap, had dinner prep interrupted with company coming . . . you get the picture.  No message, just silence.  I hung up after several seconds.  This repeated invasion of my privacy is extremely annoying.

Ok, I blocked 206-762-8519.
Per Sprint cell phone customer svs, here are instructions:
- Under Menu, go to Settings
- Go to Security options
- Block code is the last 4 of your phone number
- Then enter the "special number" (this is a very special procedure)

I am so tired of this number called me. Called it and recording says: "Welcome to the Quest Business Messaging service. Please enter your mailbox number." I am going to try to block the #.

Makes me wonder if there is some sort of phishing scam going on.  Perhaps this guy has a list of identities that hes is confirming by calling the numbers he has on his list and verifying that the person still lives there.  Call me paranoid, but sounds plausable.  Keep an eye on your credit folks.

Some guy just call our house a few minutes ago asking for my wife.  I asked if he would like to leave a message and he replied "no, there is no message".

Caller claimed to be a union member named Ken Jones who asked me who I was voting for in the governor race. I told him and he hung up on me at mid sentence.
He was not a union member. There are no union phonebanks today. I checked.
I don't know who he really was but it's a fraud.

Caller did not identify herself, asked for my girlfriend, said that she would try back in a bit, and hung up abruptly.

A call back to this number dropped me into a messing service that asked for a mailbox number in order to proceed (dead end).

USsearch.com says that it is a Qwest land line with phone type Seattle Duwamish 5ES (whatever that means).

Intelius.com lists it at coordinates 47.54 N, 122.31 W.  A search for these coordinates using Google Earth shows that it maps to the runway at Boeing Field (another likely dead end).

I just had the same thing happen.  206 is Seattle area code.

Caller hung up when I answered.
