FYI, I spoke with my primary carrier - TWTC - and they report that there are no additional costs for setting up TBCT functionality. However, they require a provisioning request (aka paperwork) so I can't set it up right away. I'll probably get it set up in the next few months so that I can play with it using my NEC 2400 or possibly my IAT dialer... When I go to sign the paperwork that's when I'll get all the nitty-gritty details like how many concurrent calls, etc. I'll report back to the lists when I have that info. -MC
