Does the Echo Canceller work with cards that do not hardware or software Echo? I mostly use OpenVox cards with no EC. Thanks
The software based Open Source Line Echo Canceller (OSLEC) should work on all cards, as its software based See here: http://www.rowetel.com/ucasterisk/oslec.html
so if there's no soft echo loaded at all then the echo canceller is not doing anything when activated?
Elastix comes with OSLEC, so yes when you see it is activated, it means its working, probably independent from hardware echo canceling. Ive never used anything hardware-based before, OSLEC does a brilliant job!
