I have received calls from this number with the 793 area code, I also get it from my local area code.. Strange.

Called again 6/27/11 at 1:50 PM. No message.

Received numerous calls from this phone number. Never leave a mssg - always hang up before recorder picks up.  Sick of it!

computer recorded message asking if I wanted to reduce my mortgage payments... said the press 1 for more options when I press 1 it hung up... I suspect it was some sort of scam to get my social security number..

Got a phone call from this number. The caller left no voice message.

Received a call from this number. They didn't leave a message.

Received a call from this number; the caller ID had no name. I tried to research it by looking it up in the website of the North American Numbering Plan Association, the organization that assigns area codes. It seems that 793 is an "Expansion Code." In regard to what NANPA calls Easily Recognizable Codes, we have the following:
"The format of an area code is NXX, where N is any digit 2 through 9 and X is any digit 0 through 9."
For N9X codes: "The 80 codes in this format, called expansion codes, have been reserved for use during the period when the current 10-digit NANP number format undergoes expansion." (http://www.nanpa.com/area_codes/index.html)

The only way this number can appear on your caller ID is if it's a foreign phone number; then only the last ten digits of the phone number appear on your caller ID. We don't know how much of the city code or country code, that may precede the last ten digits, has been cut off.

I'm getting more and more kinds of these calls. Since you can't call back, you can't tell them you are on the no-call list.

received call from this number and they left no message

This is creepy. Sometimes it's unknown caller, unknown number
Today it was this 793 number.

Received call from 793-390-0100 - number identified by caller ID.  Left no message, in fact, did not ring enough times to activate voice mail.

Called using an auto dialer.  My machine ansered before they picked up looking for Danny? (Wrong number) They hung up quickly after that.

left no message.

Not the first time I've had a call from this number - and you can't call them back!  Surprise!
