Hello, I download Sipek, which bases on PJSIP. I found big echo problem, while two persons talk through microphone and speaker on laptop computer. The noise makes communication imossible. Could anyone tell me how to resolve this issue? Thanks. _________________________________________________________________ MSN新版在线社交网络，与您的MSN好友更全面互动！ http://im.live.cn/msn9/

Maybe sipek didn't enable echo cancellation by default. Just a guess. You can have a try pjsua, make sure to enable echo canceler at cmd params. It works well when I try my sipua DLL at windows XP/Vista. You may also take a look my customized code when I get a repository to put soure code. regards, Gang 2009/2/12 TanMeng-en <mengentan@hotmail.com>: > Hello, > > I download Sipek, which bases on PJSIP.

Hi, Gang, Thanks a lot. Your experience encourage me a lot. Here, I want to confirm my test environment again with you. I want to use the speaker phone feature over laptop, i.e. I use speaker and microphone (not earphone) on laptop. While I using Sipek, because of acoustic echo, I will hear many "bi bo..." noise. It seems the AEC feature of Sipek does not work. Would you please confirm me that you use speaker phone feature, and AEC works? Thank you very much. When will you put your customized on repository? And is it possible for you to send me a copy first? Or would you please tell me how to set AEC enabled on Sipek, and I can test by myself. Thanks again.
