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????????????MSN???????? http://im.live.cn/msn9/ -------------- next part -------------- An HTML attachment was scrubbed...
