Hi, I need to setup an Asterisk box with 4x ISDN BRI links. Looking at the specs of various cards I favor the Digium B410P and Sangoma A502D because of hardware echo cancellation. Does anyone have any experience with either card, good or bad? Which one would you choose and why? Thanks for your insight. Regards, Patrick
I have a box running a TE410P with echo cancelling and it works like a charm. Set up once, forget about it.

We have tested both and they work fine. The Sangoma is much easier to install as it does not depend on any other driver, you just run 'setup-sangoma' and follow the instructions. You don't have to fiddle with the linux kernel or zaptel or chan_misdn. It just works. Plus its more modular. You can chose 2/4/6 ports to buy and if you need more just add remoras up to 24 ports. The Digium card is fixed to 4 ports, period. Having said that, make sure you stick with the version that has hardware echo cancel and not even try the other one. We made the mistake of buying the first time without echo cancel expecting to test the 'software echo cancel'. But there is no such thing as 'software echo cancel' on this card. I do not even understand why Sangoma would make a version without the hardware echo cancel. You get some degree of echo on practically every call. Andres.
