[Linphone-users] Why isn't the echo cancellation working?

[Simon Brenner]

Hi,

can anyone tell me why the echo cancellation of my Linphone isn't working?
I'm using a git Linphone on Linux. I'm setting my ec with

ec on 256 256 256

It seems like I'm getting 100% echo...
Any suggestions?

Thanks,
-Simon.
