I got a call from 621-0541 last night around 8:50 pm.  I called back this morning and it also said that this number was not in service.  Kind of creepy eh?

I got this call at 4:00 am.  Called back answering machine said leave a message.  YOU HAVE GOT TO BE KIDDING.  Also the call came in as California.

I received a call from this number and no one was on the phone when I called it back it said number no longer in service

That is correct, it is some type of international thing when someone calls.  They are using thier own phone, but the caller id is 760-621-0541.  I hope this helps

I just got a call from this number...my friends in Hong Kong use Skype or one of those voice over the internet providers. My cell is 760 area code so maybe it is some international and calling card/ voice over the internet shared number...usually my phone says Unknown caller instead of 760-621-0541 when they call me.

I got a call around 11:25 PM and it was a Rick Roll. Weird...

it is a calling card i my husband called me from china and the same number 0541 came up when i called it back is said it was no longer in service.

i bought a calling card in to make a long distance from toronto to a friend with a san diego (760) phone number. i normally would have a 416 area code, but usually the calling card will change my number to show up as unknown.  today my friend asked me if i was in san diego because this 0541 number showed up on his caller id.  i thought that was strange so i ended up here looking it up.

I just got two unknown calls, when I picked up and said hello, no one answered. then a minute later I got a message with a distorted voice which sounded like "bi*** I'll beat you up" when I pressed the button on my voicemail to return the message sender's call and it repeated that number. it rang forever with no answer. but when I dialed it myself it said it was disconected

I just got a call from this number too! I mised it and called back 2 minutes later and there was a recording that said the number is no longer in service...I live in the San Diego area but I thought it may have been someone from Palm Springs at first.

Call came in and no one was on the line or was unresponsive.  When I called back the number that showed, the phone only had a quick busy signal as if the call didn't go through, not the normal type.  I tried several times but always received the same signal.  Maybe it's a computer generated call?
