Received a call from this phone number.   I did not answer and no message left.

No message left.  This is head hunter (Param Solutions).

Received call from this number, which I let go to voice mail.  Caller left a message; it was a recruiter from Param Solutions.  I believe he got my number from an online resume post, so it was not really unsolicited. (800Notes - you should add a Call Type option for Recruitment/Staffing.)

Outside recruiter.  They've always been a complete waste of time

We also received calls from this head hunter. Must agree with another poster: they will waste your time if you give the the chance, but they'll do nothing for you. They're rude, incompetent and useless.
