FYI, from the Oslec mailing list : Interestingly I get very bad echo with dahdi using any of their supplied echo cancellers as well and It's interesting you mention more echo problems with dahdi - I've done a very quick OSLEC port to test it functions and it seems (from /proc/oslec)to be working ok, however I get very bad consistent echo regardless of the choice of echo-canceller ... and from the SS7 list Same here, dahdi make terrible echo...
