Called my cell. I didn't answer. I called back from a land line, and got this (familiar) message:
"7-9-1 The message you have dialed is not in service"
Different # but same program, repeated, unwelcome telemarketer robo calls. "Hi (pause) This is Nicole Brooks." Sounds almost life-like. Really sophisticated computer but "not quite!"
Don't know what the computer is selling/seeking as it hangs up every time a potential probing question is asked.
