I’ve been running asterisk for years with Digium TDM* cards. I’m looking to migrate the asterisk server to an Intel Atom D525-based unit and to do so I need to purchase a PCI-E AEX* card. However, I’m trying to determine if my existing card has the hardware echo cancellation module. Short of unracking the server and taking it apart to look at the card, is there a way to figure out if the card has the echo cancellation module? (System is Debian Linux, Asterisk 126.96.36.199).
Related to that, does anyone have experience with the D525 platform? Will an echo cancellation module even be needed for a minimal workload? (Two PSTN lines, up to 3 VOIP calls simultaneously).
Thanks for the assistance!
