The number called my cell twice and left a unintelligible message.

Got a call from them - they are a recruiting/resourcing company. Bascially, I think they got my details from Monster.com and cold called to fill a contract position. The line was really poor quality, in fact they had to call me again on a different line for me to be able to hear what he was saying (although that was just as bad). As soon as I said "I am not a contractor" they hung up without as much as a thank you or goodbye.

I don?t know if this will work for all phone companies, but if you have Comcast, you can block the number with a call screening option on your phone.
To activate Call Screening dial *60 to activate this option.
If the person you want to screen just called, you will be prompted to dial #01#.
If you want to add the number to the list, have it handy and follow the instructions as prompted.
It?s a great service and they will only be able to call you once!  
If you want to stop all private calls coming in dial *77 to activate.  This will not stop Anonymous calls, but if the person calling is intentionally blocking their number, they will not get through.

By the way, these services are free to me as a Comcast customer, but again, I don?t know if they work for other companies or if there is a charge for it.

Hope this helps!

2 calls went to vm, but they hung up right away.
