I try the patch note (0108778)from timking. It's works fine with libpri <
1.4.11

So, in Europe, telco use power safe. When a call is finished, the
D-channel shut down...
With Dahdi or libpri, how is possible to use power saving?
Which paramters I must change for that?
It's the same think than puzzled note: (0108344)
