I have been wondering about echo canceling, it seems to be one of the major problems people have with asterisk. I've gotten it to acceptable levels (using mark2 aggressive), but everything I've read indicates that the echo canceling software isn't very effective.
My question would be, what do we need to get an effective echo canceler (in asterisk software)? Is it patent issues? No experience (I know I don't know anything about how to write a echo can algorithm) or just getting the right people interested in writing one ($)?
With digium offering hardware echo can, I can only conclude that echo can can't be done effectively in software? If it is a matter of money perhaps a bunch of users can offer bounties for someone (or some company) to write an good echo canceler?
With the amount of money that a hardware echo canceling card costs (+$1000 per T1/E1) if half of this were spent on a fund for software echo cancel it would seem we could do it (if it is even possible using todays technology??).
I don't mean this as critical of the developers who have done so much, just an honest question what we (as users) can do to help improve the product.

Hi
Just wandering what solution worked to eliminate echo on your setup.
I am trying every solutions I can find on the wiki and none is working
perfectly.
We have asterisk 1.2.0
3 x digium TDM400P
30 Snom320 + 5 Snom360
For now the best setup I have is using Mark2 Echo cancel.
Thanks
Patrick
