I contacted the T1 Card manufacturer (Digium), This problem seems similar to a known issue whose resolution is currently in progress. One of their driver engineers has some new code in Zaptel that may help in this case. I did implement it and hopeful that should resolve it. Digium has excellent customer service and quick response time. I usually don't get that from a company. <br>

several components replaced by Dell on one of the affected servers to<br>no avail. After many months of banging my head against a wall I<br>stumbled across the following posts on the Trixbox forums:<br><br><a href="http://www.trixbox.org/forums/trixbox-forums/open-discussion/acpi-default-install-2-4-0" target="_blank">http://www.trixbox.org/forums/trixbox-forums/open-discussion/acpi-default-install-2-4-0</a><br>

<br> After talking to some computer engineers at a few companies I learned<br>that It seems Dell does not have very good quality control on the<br>power control chipsets that they use and so on some machines you have<br>to disable acpi(or enable it) at the kernel level. If you do not set<br>
it correctly, when the power saving functions trigger there is a<br>higher likelyhood that an error will occur leading to a kernel panic.<br><br>This is most likely the same problem so take a look at the forum<br>postings and try disabling/enabling acpi in your grub startup.<br>
<br>Of course it could be something else entirely, but this problem does<br>seem to be common with Dell 2950, and this did fix the problem for me<br>on more than one Dell 2950.<br><font color="#888888"><br>MATT---<br></font>
