I am receiving calls from this number but nobody speaks when I answer the phone. When I called this number back it says number not in service.

Got a call from this number.  Missed the call.  When I tried to callback, it was busy.  After reading all the comments, I'm glad I missed it! Thanks!

just looked on some other sites and this seems to be an issue with alot of people, however the rcmp and the opp have apparantly set up a joint task force to deal with this after several complaints about the same thing, which they call phonebusters 1-+1 888-495-8501

They said they were "I-Talk" a chinese phone company...I asked to speak to the manager and was told that I would be called back!
And the number...busy or not in service...

called me today at 2:08pm.  the caller identified herself as monique from montblanc and wanted to speak with someone at our office.  told her he was not available and she asked if he would be back later today, i said no can i help you with something.  she paused and said she would call back later.

lots of background noise and she didn't sound very professional.

If next time this number calls again with some obscene topics, just have some guts to keep this frick on line and use your cellphone calling police to trace him. it is federal offence to use pupblic communications for harrasing people.Another suggestion is never to give your phone numbers when filling up forms when attending trade shows. I just got my new phone number and everything was OK, but this crap happened AFTER I filled registration form when attending Canadian Manufacturing and Technology trade show in Toronto.
