Who called from 8058951743

I received a call from this number asking for the person who blah blah, I just said it was the wrong phone #, and they said oh sorry.  What is this?

How do you know that?  I just looked at our last AT&T Mobility bill, that number is not listed anywhere on our bill as the "voice mail number".  It is not on our bill anywhere.  So how can you say it is the "voice mail number"?

I got a call from this number yesterday. They asked for a person (who is not me) by the name of Louise. I told them that they had a wrong number.

805 is my local area code, central coast California.

ATT mobile is my cell provider. Seems like they should know who has this number if it was a call from ATT.

We know it's ATT's voicemail number because when we call our voicemail, that number shows up as being dialed.

Same Cingular voicemail number, pre-programmed on speed-dial #1, if you accidentally press #1 for extra second, it rings up Cingular Voicemail and be charge for mins of it. Just builtin "feature" alone will increase their profit umpten fold.
