Hi all, I've developed an application using PJSIP for Microsoft Windows Mobile 6.x devices and I've been testing it on some devices. Unfortunately the audio latency is very high on both devices (Samsung Omnia II and LG LM730). Values are typically as high as 700ms, measured from end-to-end. I've checked your wiki: http://trac.pjsip.org/repos/wiki/FAQ#audio-latency And also this ticket: http://trac.pjsip.org/repos/ticket/783 I've done several tests adjusting the parameters but results haven't changed. Running 'pjsystest', the average value is 400ms for both devices. Has anyone faced this problem already? I've done these tests on a local network with a low network latency so I do not quite understand the 300ms difference between the end-to-end test and pjsystest. Any clue on the problem behind ticket #783? Thanks! Best regards, Nuno Costa

Hi Nuno, Problem behind ticket #783 is high latency issue on WM :) Agree, 300ms different is quite strange/high. It is usually useful to examine the JB statistics at the end of call (printed by pjmedia_jbuf_destroy()), e.g: if JB was used to get full, clock-drift or high burst of audio device might take place.
