Neither. The regedit posted above is for enabling VC to read the caller ID (phone number or name) of an incoming caller. Not text messages? (at least I've never seen it mentioned in this capacity, only for caller ID). There is a setting for "urgent messages only", be sure that is unchecked to hear all messages. Also be sure that your volume control (system volume, not ring) is set above zero or VC won't announce anything. I don't recall if I had any problems during the short time I had the Voyager Pro, though I don't typically use the headset to announce messages because it's distracting (to me).
