Hung up when machine answered.  We don't know anyone in Seattle.  Seattle directories don't have a listing so this may be a spoofed number.

I just got the same thing.  It shows on caller ID as "Sigma ID."  They called before 8 AM; very annoying.

Just got a call from this number and they hung up after 1 ring.

Same thing. Never heard of Sigma IT in Seattle.  There is no listing or web site for such a company.

I searched on the Web, there is a company called Sigma IT -

http://www.sigmait.org/contact.html

Same thing - range once and hung up. Two times in a row...

Caller ID says Sigma IT. Rang only once at 9:00am.

Didn't ring my phone 'cause I have an interceptor.  No idea who it is.  I never answer calls from numbers I don't have stored in my interceptor.  Left no message.

Tues Apr 13 2010 @ 11:28 PM eastern time!  Caller ID indicated "Sigma IT."  Answering machine on, and phone only rang once.  If this call originated in  Seattle, Washington as previous poster indicated, then it was 8:28 their time.  If anyone knows...isn't it illegal to call after 9 PM MY TIME #west coast of south Florida# -- not theirs!!  Besides, on Do Not Call Registry.  Sign of the times folks--resign yourselves to no longer having any privacy and peace in your own home at any hour of the day...

11:40 PM EST call to me in FL.  2 rings then hangs up.  Caller id said "unknown".

I am also in FL and received a call exactly 11:40pm.  2 rings and hung up.  Caller ID had the number and Seattle.  I called the number back and went directly to a recorded message saying thank you for returning our call, if you would like to be removed from the list press 1 etc etc.  I tried to press 0 to reach someone to give them a piece of my mind but I couldn't get anything.

Hey, SWFlorida, 10 minutes after they tried to reach you they gave the two phones at my residence a ring.  At 11:38 PM!  The phones rang once or twice and then stops.  No message, no nothing.  I am in southeast Florida, for what it's worth.

Yes, they called me at 8am but it's id reads SIGMAIT and same number.

Just got call from them here in San Diego about 8:20 am.

7:33am 4/14/10 - Same thing as all the others...2 rings, no one there, no message.

Sarasota FL here.... was called by this number at 3:48 PM on 4/12/10.  Rang once, as with all these other comments.  I called the number back and went directly to a recorded message saying thank you for returning our call, if you would like to be removed from the list press 1 etc etc.  I tried to press 0 to reach someone but their system hung up on me.   I called again and pressed 1 to be removed from their marketing list.   This may be a case of an automated system checking for active voice lines (vs data or fax) and then later a real person may call to provide a marketing message.  Why else would they ring only one time?

9:30AM.  Rang; I didn't pick up; no message left on the answering machine.  Yes, we're on Do Not Call.

Received phone call at 5:45 pm edt on 4/14.  Rang once - did not pick up.  We are on the Do Not Call list!

Same story as everyone else.  Got a call at 12:30 ish midnight.  Woke from a dead sleep.  No response when answered.  Absolutely pathetic.  Called the number back the next evening and got the same recording as everyone else.  And yes, on the do not call list!!!!

I got this call at 755am hung up as soon as I answered!!
