</div></div>The message is likely coming from the telco or from the destination number. It is a common issue. I usually put something in my dialplan to retry all calls that receive an unexpected hangup cause to work around the telco seemingly randomly sending back odd hangup causes. You should not retry ALL calls, only ones with unexpected hangup causes.<br>

calls to those numbers are connecting fine. I opened verbose logs and digged
into it more. I found out can’t dial any channels from DAHDI/24 on first E1.
Before that channel calls are going through fine. I tried test calls to second E1
and can’t dial on it either. </p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">When I check channel or E1 status it is showing fine.
Checked chan_dahdi and system conf files and see all channels are configured
fine. </p>
