Which boards don't support that? If DSPs on board, echo-cancel should be
available.
I have in my hands right now a DIVA Server BRI-2M-PCI (not the 2.0
version) which own its dsp but doesn't echo cancel, due to old capi
drivers which don't support this feature. Newer eicon drivers won't run
on this board.
Yes, that should be possible.
But I don't think a channel driver (and each channel driver) should do that
on its own. Software echo cancelling belongs in a common part of Asterisk.
I strongly agree. But asterisk doesn't seem to work this way. Zap
channel has it's own echo cancel engine. Other channels don't.
This is so sad :-(
Why not implement a really common echo cancel api usable from any channel ??
