I actually found this hours ago, but couldn't find it on my phone (I didn't want to send you bunk). When I read further at home, I realized that it is on Moto phones only (I am on a Sammy now, although I have used Moto's before, that's how I caught on to your angst). Anyway, I think this is the solution:
Settings -> Call -> Call Alert -> Call Status Tones Once there, you can enable/disable the 'Call connect tone', 'Minute minder' and 'Call end tone'
Please let me know if this works.
