I have a customer that retired from the Big Bell phone company as the voice of AT&T. I have a sample sound bite on my phone server which you can reach by dialing:
1-360-717-2960
or
She is just getting started in this on her own, so I thought I would let you know. If you want more information, call me and i will put you in touch.
By the way, it is worth calling and listening. The sound bite is pretty funny.
