Who called from 4807399434

automated voice message as follows "conference call starting right now press1 to join in, to delete yourself from the conference call press 9. thank you for choosing conference now simply press 1 to join in on the call  thanks for using conference now, your conference call has already started .
Then the female robot voice repeated six times in a row " to add your number to our do not call list press 9.."

This is a scam. A RoBo call with a  'spoofed' caller ID claiming there is a conference call for you. Hang up and block the number.

Got robo spam on saturday, 28mar15, 12.17 pm, on my cell # from 480-739-9434. No message, I'm familiar with the phony "conference call" mentioned in the other posts above.
