[asterisk-users] Digium B410P or Sangoma A502D?

[Matt Watson]

I haven;t used any BRI cards but... call me crazy but wouldn;t they still be using Zaptel (even your sangoma... the script might just be configuring it for you)...

and btw, software echo cancel happens in the zaptel kernel driver... it has nothing to do with the hardware (hence why its a software echo cancel)....

You also would of had the option of buying HPEC licenses for software echo cancel from digium for a rather cheap price.

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.
