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)...<br>
<br>
and btw, software echo cancel happens in the zaptel kernel driver...</blockquote><div> </div><div>I think (but I'm not certain) that it's correct :<br>Digium's B410P are used through chan_misdn.<br><br>(Please, do not hesitate to correct this)<br>
<br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">it has nothing to do with the hardware (hence why its a software echo cancel)....<br>
<br>
You also would of had the option of buying HPEC licenses for software echo cancel from digium for a rather cheap price.</blockquote><div>This also doesn't apply to chan_misdn hardware ... <br></div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

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