[Linphone-developers] voice delay 5 seconds when ec is off

[孙德奎]

Hi, There, 

I have port the linphone to arm board(linux-2.6.30).

and have build the audio call between pc and arm board. 

if I close ec(echo cancellation) with the command "ec off", after a period of audio call,  5s delay happens and will keep about 5s delay.

if I didnt close ec, everything works ok. 

but I want to close ec as it can decrease CPU loading. 

could anyone help me about this？

Thanks！
