I doubt that the energy-saving is causing the trouble. How do you get the ISDN-signal? Is it an 
S0-bus? If yes, I may be able to be of further help. Even if the connection goes down, it should 
not matter for P2MP connections. But S0-bus problems can be nasty (though seen rarely these days).

I would bet on the 2nd choice.

I doubt that you do get anything useful if you pick the wrong mode.

Are you sure that your are not dealing with termination issues? Try sending a T.30 fax with fine 
resolution and ecm enabled when your connection is up. If it takes too long or fails, this is 
something to look at.
