    1717 * You MUST make sure that the loudspeaker level is set high enough so that the speaker output is fed-back to the microphone (i.e. we deliberately want to capture the audio echo)

     22For this article, I run the test on an Windows XP SP2 desktop machine with on-board !SoundMAX audio device. The test uses PJSIP version 0.9.0-trunk and default pjmedia settings. The default settings should provide reasonable value between latency and stability, and as explained in [wiki:FAQ#audio-latency FAQ on audio latency], you could always tweak the settings if you want shorter latency.
