Why don't you contact Digium tech support? They should be able to help<br>
you narrow down the problem. Cards do go bad from time to time.<br></blockquote><div><br>Time to time, I would say with great regularity, especially since most people don't put surge protection on their POTS lines.<br>

Now on to Steve's reply...<br>

</div>I agree, especially for a small office or home. You can set up most SIP<br>
providers to failover to your cell phone if there is a problem with the<br>
SIP connection. Do this and you won't need a hardware card.<br>

<br>
</div>Seriously? This makes no sense at all. Even early TDM400p cards will<br>
work with dahdi, usually better than they did with zaptel, but no worse.<br>
The version of Asterisk and zaptel from 1.5 years ago is likely full<br>
of bugs that have been fixed by recent versions. Are you still driving<br>
your 1978 Ford Pinto? Someone from Digium made a post to that effect a<br>
week or so ago. If you're running version 1.4, you should be running<br>
1.4.28 with the latest version of dahdi.<br></blockquote><div><br>Do you believe everything you hear/read. One of the major Digium dev guys once said that his code was not "Beta" anymore, and therefore bug free.... I still get a kick out of that one. <br>
</div><div><br>Yes, seriously. The OP made it sound like a new problem. Obviously he was not running DAHDI 2.5 years ago. When cards and/or modules go bad, they generally completely die. Newer code introduces new bugs. <br>
<br>Revert to the version that worked for you previously.<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"><div> </div></blockquote>

</div>That would be nice of you, but he should find out the problem before<br>
throwing more hardware at the issue.<br></blockquote><div><br>What can I say, I am a nice guy. I will not be deploying any of these cards except for timing and a empty card with no modules does just fine. Anyways, it is hard to find any new server boxen with the older PCI slots.<br>
