Hi, What is the PJMEDIA_ECHO_DEFAULT and PJMEDIA_ECHO_SIMPLE? I tested both PJMEDIA_ECHO_DEFAULT & PJMEDIA_ECHO_SIMPLE in WM6.1 with 1.0.3 version. The CPU load is around 25% in PJMEDIA_ECHO_SIMPLE, and 10% in PJMEDIA_ECHO_DEFAULT? The PJMEDIA_ECHO_SIMPLE has higher CPU rate. Is this right behavior? What is the best EC (voice quality) for WinCE6.1 with 500MHz? Thanks, -fcch -------------- next part -------------- An HTML attachment was scrubbed...
