have received a few calls from this number -- on both my phone lines.  i am on the do not call list, so they are dialing all numbers in the exchange it seems.  they claim to be sbc messaging (am not an sbc customer) -- i redailed the # to hear it and they are selling something but i did not listen to the message long enough to know what.  it's all computerized/automated -- no live person.

Every time I've received the call, probably about 11 times now, the recorded voice states; "Due to a technical problem on our side we are unable to speak with you directly"  They then just disconnect.  I called the number and got only a message.  They say they are exempt from the do not call list.  They are selling tickets for a charity.  They ask you to state your telephone on the answering machine to be removed.  I would guess it is safe to leave number, since they already have it.

Have received several nuisance calls from this number, at varying times of the day.  Always "Due to a technical problem on our side we are unable to speak with you directly".  It's like why are you calling them.  Says it's "SBC Messaging."

This information maybe of use to those wanting to call

I called 650-878-4807 & it sounds like a police charity org soliciting donations. These organizations are exempt from the Do Not Call List.
