Just a random call that hung up right away without answering, but only had 3 digits in the last part I thought was to have 4.

I keep getting calls from 206693437 also.  No one there.  Thought it should be a 10 digit number but this one is just 9 numbers.

Could not understand it cut in and out

Got a call from this number. Its missing the last number. Anyone know???

I have been having a great deal of scam/spam type calls in the last week and do not answer my phone unless I know who is calling.  I got a call from this same number, but my phone display showed it as 20-669-3437 as if the area code is missing a number. I suspect this is an over-sea's computer connected scammer number... for in looking up the other calls I've recieved, it was reported that many of those that answered calls from one of the scam numbers were calls from people with out of the country accents (possibly Indian). I've blocked all the numbers as they come in and I can tell when they try to call again for it rings once and hangs up and they try calling back on another number.
