quick alarm on the trunk, OK->RED, 1-4 seconds later,

If it's this problem, a dahdi restart will rectify.<br>
Let the developers know, I'm trying to get 100% rid of all MFC R2
with Asterisk due to this kind of issues, but ISDN is impossible

<div>Unless I just got blind, everything is
by the book (and this setup was working fine).
These are the specifics of the system:</div>
<div><br>
</div>
<div>OpenR2 1.3.2</div>
<div>Asterisk 1.8.21.0</div>
<div>Digium Wildcard TE121</div>
<div>Carrier: Telmex (México)</div>
<div>CentOS 6.4 (just recently did yum -y
upgrade so everything is the most recent version
as of today)</div>
<div><br>
</div>
<div><br>
</div>
<div>Apart from checking the config files
again and again, this is what I also tried:</div>
<div><br>
</div>
<div>- Plugging/unplugging the cable</div>
<div>- Rebooting</div>
<div>- Switching the card from PCIe slot </div>
<div><br>
</div>
<div><br>
</div>
<div>As you can imagine, Telmex says "its
fine from my side". Since everything started to
malfunction with no users involved, my guts tell
me its them, not us. How can I prove it with a
Digium card? I know the commands from Sangoma for
wanpipe debugging, but this cards are not my
strongest point when it comes to debugging. </div>
<div><br>
</div>
<div>Any ideas? Any commands I can execute
to mail Telmex and prove whose fault is this?</div>
<div><br>
</div>
<div>Regards,</div>
