I can dial 1-24 channels but not after that. There are 8 E1s. Box was working fine and carrying traffic on all E1s before. Just recently i noticed this problem has occurred. <br><br><div class="gmail_quote">On 13 May 2011 16:30, Rafael Visser <span dir="ltr"><<a href="mailto:visser.rafael@gmail.com">visser.rafael@gmail.com</a>></span> wrote:<br>

And check the system.conf either.<br><font color="#888888">

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.
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.
Could you please help?</pre></span><br></div><div><div></div><div><div class="gmail_quote">On 13 May 2011 15:07, deeps backup <span dir="ltr"><<a href="mailto:backup.deeps@gmail.com" target="_blank">backup.deeps@gmail.com</a>></span> wrote:<br>

</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>
