</div>I have no idea. But other than the error you have given very little<br>
information to go on. Which card are you using, what type of ISDN line<br>
(PTP?), what's the DAHDI or Sangoma (or...) and Asterisk configuration,<br>
what do the log files say, etc?<br>
<br>
Have you tried calling the vendor of the ISDN card for support?<br>
<br>
Regards,<br>
Patrick<br>
