.....why would anyone want such a list apart from your research project ???
Nothing personal, but just saying. I think you are going to have to call directly to confirm the recorded messages.
Has anyone compiled a list of the standard recorded voice messages used by the major carriers? ("To leave an automatic voice message, press 8 or wait for the tone" etc etc) I'm providing analytics for a big call center, and this information would make my current project a lot easier!
