</div>No but there is a bug report with a lot of information that seems<br>
similar: <a href="https://issues.asterisk.org/jira/browse/14031" target="_blank">https://issues.asterisk.org/jira/browse/14031</a><br>
<br>
In Europe telco's drop the D-channel (cut off power) to save on the<br>
electric bill. The libpri/dahdi/asterisk combo should detect a dropped<br>
D-channel and signal the telco to fire up the D-channel. Judging from<br>
that bugreport ("Unresolved") it seems Digium has still not succeeded in<br>
properly handling this situation.<br>
<br>
Should you not be able to resolve this issue and really require an ISDN<br>
BRI connection then have a look at an Eicon Diva or Sangoma card. Both<br>
cards+drivers properly handle a dropped D-channel. I have used Eicon<br>
Diva and Sangoma BRI cards in the Netherlands and they work fine. Or you<br>
could get a blackbox from Beronet, Patton, Audiocodes etc. If you feel<br>
adventurous you can also get a BRI card with a HFC-S Cologne chipset and<br>
get the latest and greatest isdn4k-utils, mISDN, mISDNuser and lcr from<br>
<a href="http://misdn.eu" target="_blank">http://misdn.eu</a>, build, install and configure lcr to talk to asterisk. A<br>
few weeks ago I set it up and did one test call and that call worked<br>
fine. Use at own risk :)<br>
