This number called at 3 a.m. this morning.  I thought this was against the law.  Why is there a no call list if these idiots can call anytime they want?  

Two calls from this number to my work number (which is relatively new) - Friday, 4/11, at 10:27 pm CDT, and Monday, 4/14, at 1:29 a.m. No voicemail left.  I can say I am most definitely NOT at work at these hours....

Got 2 calls from 626-207-7204 forwarded from work phone,  10pm and 3am.
I didn't answer.
Take off eh..

called buisness number. Nothing but an open line, then a disconnect. creepy.

After midnight last night, my phone rang and it was this telemarketer! How can I stop this immediately?  And really - after midnight? I thought there were laws addressing such unacceptable marketing practices!!

Forgot to mention, I'm in the Chicago area. Caller ID said "Pasedena CA area"

Received 4 calls from this number last night (3 calls in quick succession around 1am, then the 4th call around 4am). No voicemails. Picked up third call and was immediately disconnected. Will be blocking!

I got 2 calls from the same no.

Received call from 626-207-7204 CA. {Phone area code). They did not answer after saying hello 2x.
Calling my # in MA. at 2:24AM (EST).

Got two calls from this number (at work, that too) which I luckily missed. Have no intention of calling back especially after reading these posts.

Three days of nuisance calls at early morning times. Rolled from my desk line to my work cell. Blocking them now as I haven't fallen back asleep.

1 am and 4 am CA time. Didn't answer, no voicemail.

Got 2 calls in one night; 3 am and 4 am. Answered the second but said nothing. After 15 secs of silence, they hung up.

6:30 am?  REALLY? California

Just got 2 calls from this number. I didn't answer and hoped they left a vmail but they didn't.

They call me at 10pm. On cellphone and my work phone. 9-10 times each. No person and no voicemail. Like a prank call. What do these idiots want?

Received 3 calls (forwarded to my cell from my work phone) at 2:02 a.m., 2:41 a.m. and 3:30 a.m.  I did not answer & they left no message.  I finally turned my phone ringer off.

Called at 1:06 this morning California time. No message

Just got a call on my office phone.

Rang twice, I answered but nothing was there.

Called 1:37 am in NJ. No  VM

Looks to me like they're sequence dialing. I have two separate lines on my Chicago office phone, and this number called both of them while the office was closed on Saturday. They called the lower number at about 8:30 AM and the higher number at about 12:20 PM. The difference between the two numbers is about 1200 in the last four digits (everything else is the same). If all those numbers were dialed in between, it would come to a rate of 5.2 calls per minute, or a call every 11.5 seconds.

two late night  calls within 15 min of one another, at around 3:30am. No one there.

This number called me late last night at 11:55pm and early in the morning today at 2:14am.  I am in New Jersey.  When I answered hello, no one was replying on the other line.  A bogus!  This has to stop.

Ha! Well, I'm glad it's not just me... two calls at my work number this week, one at 2am and one at 12:30am (I'm on the East Coast, so if it's an idiot trolling in CA, the timing makes a little more sense), no message...

These bungholes called me at 2:30AM last nite, 10:30PM the night before, no message. I've received several calls in the past two days, nobody is ever there.

They called my "office" line at midnight - woke me up from a sound sleep.  no message.
South Dakota

Just called and left a 26 second voicemail with nothing but white noise on the background

just a call. no voicemail left, other than "pasadena area"

I agree we should all call the number repeatedly.

I started getting calls from this number months ago.  Once in a while a human actually talked.  I asked to be placed on the do not call list at first, but it just kept up.  Now I get a call from that number at least 4 times a week, generally around 4:00 - 5:00 PM Pacific time.  I've repeatedly dialed it back and hit "1".  they say they will put my number on their Do Not Call list, but they never have.  AT&T says I can't block them or file a complaint; they are just a nuisance.  I have them identified in my Contacts as "Ignore this call."  Now I don't have to bother when they call.
