They called but left no message; I don't pick up the phone if I don't recognize the number.  I'm on do not call list.

Didn't answer, no message

This was a recorded message delivery trying to sell Medicare/MediCal supplementary insurance.

no caller id, just said LA.
No voicemail left

Received a call from this number about 11:46 a.m. today, and when I heard a canned message about Medicare or Medical, I immediately hung up.

I am on a "Do Not Call" list, but it doesn't stop me from getting these annoying calls.

Pac Bell and SBC are no longer in existence, having been changed to AT&T.
