BTW - E1's are 32 channel (not 31). It's 30B+2D.<br>

I didn't understand very well.. So you cant dial on the first 24<br>
channels?<br>
Did you take care on the jumper of the card?. There is something<br>
related to E1 (31 channels) or T1 (24 channels).<br>
And check the system.conf either.<br>

I have checked destination numbers are correct as otherwise calls to<br>
those<br>
numbers are connecting fine. I opened verbose logs and digged into it<br>
more.<br>
I found out can't dial any channels from DAHDI/24 on first E1. Before<br>
that<br>
channel calls are going through fine. I tried test calls to second E1<br>
and<br>
can't dial on it either.<br>
<br>
When I check channel or E1 status it is showing fine. Checked chan_dahdi<br>
and<br>
system conf files and see all channels are configured fine.<br>
<br>
Could you please help?<br>

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