Hi Sebastian,

It is my peer who hears its own echo.

If I use a headphone it suppresses the echo.

Hi Alexis

Normally the echo canceller suppresses echo on the near end (Linphone). From your description I guess you are talking of the far end echo. Does the echo depend on the call participant?

I just started using Linphone Android 3.2.7 on a LG G2 cellphone running on Android 4.4.2.

Even if I use the echo cancellation option, I can't get rid of a (very annoying) echo on the distant phone as well as a (slightly less annoying) delay between each phone.

I wonder if it might be caused by a interference between a built-in echo cancellation on my phone and Linphone's echo cancellation. Using Linphone's automatic calibration, the parameter is set to 330 ms, but I can't choose it myself on the app.

Thanks for your help,
