I did, but I guess I did not pay enough attention...

So, knowing my card (a Digium TE-110P, which AFAIK doesn't have any
hardware echo cancellation module)...
Which software echo canceller should I be using ?

Is see that there are particular software configuration available ,
but I haven't had a clue on what they are for, nor did I find
documentation about it...

I'm not building asterisk nor dahdi myself, but instead rely on
packaged from ATrpms.conf

Thank you
