Hi guys

I am playing with this VoIP board here, I have the VoIP enable, but I still got the echo problem, is there something I don't know here?

I am using point to point setup here.

Thanks guys!

 

It sounds as if the echo cancellation is not working (well) in the development kit. For evaluation purpose, I suggest to use headsets. This should totally prevent echo. Alternatively, if the development kit supports SIP (standard signaling protocol) then you can try a centralized AEC software like PBXMate.
