I am absolutely not 100% sure on this, but I don't think the record-on-demand works yet. (I can't wait until it does work.)
If you are using AAH or just AMP, you definitely need to install the Call Recordings Manager. See this thread:

This link also includes specific instructions on how to install it if you are not a Linux guru.
