     3Testing is done with pjsua on Mac with the following setups: No echo cancellation at all (ec-tail = 0), stereo mode, and mono mode.

     5For stereo mode, you can clearly observe some echo cancellation compared to the testing without ec, however you can also still notice some uncancelled echo. And this is especially more noticeable after you compare it with mono testing, where the AEC seems to work pretty well and manages to cancel most of the echo.

     7Note that this ticket only updates the Speex DSP part to version 1.2, but leaves the codec part untouched.
