At the moment, I'm having trouble with lines going up and down all day long.<br>
I asked them to be created as P2P.<br>
Mostly but not always calls are passing in and out correctly.<br>
</blockquote></div>
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).<div class="im">

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
So, if I'm not mistaken, either :<br>
- these lines are configured as P2MP (and not as P2P as required),<br>
- I'm facing something else I've never met before.<br>
</blockquote></div>
I would bet on the 2nd choice.<div class="im"><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
As these lines are up most of the time, I'm having a hard time to get any useful help by Telco beside "level 1" basic checks.<br>
<br>
For the record, these lines are terminated on my side with a Patton smartnode (most of the time, I use Digium BRI boards).<br>
During off hours, I'll try to check what happens when toggling to P2MP mode.<br>
</blockquote></div>
I doubt that you do get anything useful if you pick the wrong mode.<br>
<br>
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.<div class="HOEnZb">
