When these folks call, if you are on your work-desk phone, after they ask for someone...then say, "Sure; absolutely. I see him in the office room right now. Hang on while I transfer your call." Then transfer the call to their own telephone number (the one they called from). Since that number is going to be a call-center number (going to multiple phones on their end), they will end up talking to one of their own people. :)

Called, no message left.

Ahmed from Calsoft Labs called for my boss. After quizzing him extensively he gave up and hung up.  Foreign accent and sounded like a boiler-room telemarketing firm.  Would not give me a legit number for my boss to return call.  

Calling me franatically today. At home and work numbers. I hope they see it and stop the abuse. Seems like Do not call list has no affect on these boiler room operators.

Calling me and my companies main number left and right. I am sick and done with these telemarketers.

I missed the call but I confirmed my suspicions via the comments. Here is a pro tip for annoying sales people and telemarketers. Do not call and harass the voice administrator, especially ones that hate talking on the phone because it will be the last time you will ever call.

Called and asked for "Linda Morelli, IT Manager" -AGAIN.  Told him there was no one here by that name-AGAIN.  He asked "for whoever is in IT"  I just slammed the phone down.

Multiple calls, sometimes leaves voice mail of just background chatter and other times its just silence.  Called the number back but there's no answer.

Man with an accent and a bad connection (as usual) said he was from VOIP News.  He requested an IT person who is located elsewhere.  I transferred him to Purchasing.

New Castle, DE on caller ID. Man with Indian accent said his name was "John" (common name in Dehli, of course!) and asked for former IT Mgr. I said he is only available through remote contact and would not give his email address. Thought the guy was going to break into tears. He said: "Well, I need to speak to somebody!", and that's when I asked who he was and where he was calling from.  I then proceeded to tell him that we do not accept solicitation calls and to please stop calling here. We'll see if it works (NOT!)

Had three missed calls but no voicemail from this number today.

Got a call from 302-261-9122 into my sales number.  No voice mail left.  I called the number back and no one answered.  

Guy calls asking for my Project Manager - says he's from Dell, and when asked what it was regarding, he says, "I'll talk to an IT person for that."

Sure buddy.  Hope you enjoyed the sudden silence you experienced when you decided I wasn't intelligent enough to figure you out.  Mutherfucker.

Got a call, "Jason" asked if I was the sales or marketing manager. Hung up.

Received a call from this number in my work number.  Did not leave a VM.

I get call after call from this lady "Leza" asking for me direct.
I never take the call and i let it go to voice mail. She never leaves a message and calls 3x in a row only to repeat again the following day.

I received a call without a message.

There was none

Man with Indian accent asks for "Linda Morreli" (sic) or something like that.  I asked him: "Who?" And he says "Linda Morelli, the IT manager" and spells the last name!  I said there was no one here by that name (there isn't-our IT manager is a male) and hung up on him. Caller ID shows New Castle, DE.

a lot of background chatter - apparently just another boiler-room telemarketing joint.

Hang-up - no message

Daily calls to my work number.  No voice mail.

Called left no message.  Called back while I was googling the number and hung up after first ring.

Lady calls 3 freaking times in a row- 1st time gets me- claims she was "just talking" to someone but got disconnected- claimed she couldn't remember the persons names "james or john"  bla bla bla claims she is with Dell and needs to confirm something about my Boss email. I say I cannot confirm anything- she hangs up on me and calls back immediately. Hangs up when she hears my voice. Calls again and gets my co-worker and is trying to get him to confirm stuff, and then hangs up on him. whoever this is, they are scamming POS. Seriously- get a real job

Called, went to VM when i didn't know the number.  got 2.5 minutes of MUZAK

Asked to speak to marketing manager then hung up.

Also receiving calls from this number - no message, every day
