What exactly are people seeing when they have "issues" with their TDM card?

I think the best that anyone can estimate at this time is that a problem exits of some sort and it might be related to a combination of factors, one of which seems to involve specific motherboard designs. There are far too many people complaining about the same issues with the TDM card, several of which opened cases with digium support and got no response. It should be fairly obvious from the many postings on this list since that card was announced that something is not right, and at least some of those systems have digiums T1 cards on the exact same pci bus that are operating just fine. If you read through the archives, you'll see a number of people flapping their jaws using adjectives and adverbs about what they think the issue happens to be, but the majority (if not all) don't have a TDM card and apparently wouldn't touch one with a ten foot pole. What is obvious at this point is: a. no one on the -user list is going to fix (or even hint with any degree of authority) the root-cause b. don't ever post anything to the -dev list regarding a TDM card as that is NOT the forum for digium cards or drivers, c. digium support is not addressing the issue, and, d. the amount of effort required to support the TDM card (stop *, restart the drivers, start *) in its present condition is far greater then what any reasonable non-technical customer will endure. Since this has been an on-going battle, I'd suggest avoiding the TDM card totally, or, take the 50-50 risk to see how high you can raise your frustration level. > Would it make more sense to get 3 cheap X100P's and use some kind of > ATA for the FXS?

(Note: digium has removed them from their web site.) Current experience... three spa-3000's are far more stable then a TDM card, and you'll get three fxo's plus three fxs's for less money. _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
