Hello all:<br>
<br>
Over the past few months, Digium has introduced "echo
cancellation" features in Digium TE406 and TE411 and echo cancellation
with second generation firmware upgrades for TE205, TE210, TE405 and
TE410. <br>
<br>
To confuse me further, their latest TDM2400 has two types - E is with echo cancellation and B is without.<br>
<br>
So where does this leave TE110P and TDM400P? I have read much about echo problems with Digium cards.<br>
So, with echo cancellation, are TE110P and TDM400P unsuitable for
business applications? Even more confusing to me to introduce the
latest TDM2400 with and without echo cancellation. Again, is the one
without echo cancellation unsuitable for business applications?<br>
<br>
Now, moving on to Sangoma. I was always led to believe that Sangoma cards were much better at echo cancellation than Digium.<br>
Until...I read their announcment of A104D with hardware echo
cancellation. So does this make A104U as well as A102U and A101U
unsuitable for business applications?<br>
<br>
Can someone please help me straighten out my thinking? I am more
specifically concerned about smaller office deployments with TDM400P
and TE110P and A101U: Are they no good? And, is it better to use
multi-port gateways such as Mediatrix instead of TDM400P and TE1110 or
A101U?<br>
<br>
So, what is the bottom line on echo cancellation with these cards?<br clear="all"><br>-- <br>Regards,<br><br>smbPBX<br>
