Hello I'm writing using Pjsip for a WINCE device. In order to regular echo suppression will still make an echo. I decided to try Speex. But, then I encountered a problem. Whenever the person on the other line speaks, there is a noise coming backwards. I suspect that having the echo cancellation mechanism is cutting the wrong packets. By the way, when I disconnected the microphone on the CE device, there was no noise created. Thanks Eli -------------- next part -------------- An HTML attachment was scrubbed...
