                    <div>Unless I just got blind, everything is

                    <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 &quot;its
                      fine from my side&quot;. 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>
