[Asterisk-Users] Echo Cancellation

[f6hqz-m at hamwlan.net]

Hi Asterisk's people,

You can buy Digium's card harware echo can models without the echo can
module and buy it later if necessary.
They are "scalable"  ;-)

The way I look at it, it's better to have hardware echo can and not need it
than to need it and not have it.  The cards are not upgradeable to hardware
echo can and it is almost impossible to pre-determine if you will need it.
Software echo can sometimes does a good enough job but it will never be as
good as hardware.  

You get what you pay for.
