Missed call on my cell phone just now, no message.  The number appears to be a wireless number serviced by Level 3 Communications and switched from San Antonio, TX.

these greasers call and leave no message

I actually answered, and it was silent then hung up. I called back and it was busy. I blocked the number.

As usual, these types of idiots will call either between 8-10am, 12-2pm or 6-7pm.  That is:  when a company is just opening (in the US), or around lunch break, or at dinner time (in USA).  All my colleagues know I will not reply to phones during those hours, so I simply don't answer the phone and delete any message (these blokes did not leave any).  Since I am semi-retired as a university professor, but still teach privately it is convenient for me to do this.  Hint:  For new users of this wonderful service (which I highly recommend), I would advise persons from America not to use the "Do Not Call"  Registry.  It is no longer supported and according to my own sources the database itself has been hacked.  Best solution?  DO NOT SAY A WORD and block the call either with one of the newer phone blockers or a computer application.  I use one which ties my land line into my Mac G4 and I can easily block the calls.  Good Luck and God Bless!

Got a call from this number. Did not answer. Came here to check it out.  Read what was written and blocked the number.
