FYI - not trying to market any product here. Wombat (though closed-source) is free to use for small sites / hackers - if you just want to run it with a couple of phones, or play with speech synthesis/recog, it will take way less effort for the dialing part than brewing your own. It's not free if you want to fill 500 channels, but I doubt that's what people here are going to do.
