Hi Remo, If you are using PJSIP 1.5, you need to change PJMEDIA_SOUND_BUFFER_COUNT, which is defined in pjmedia/include/ pjmedia/config.h Modified definition should look like: define PJMEDIA_SOUND_BUFFER_COUNT ((PJMEDIA_SND_DEFAULT_PLAY_LATENCY+20)/20). This depends on PJMEDIA_SND_DEFAULT_PLAY_LATENCY. By default this is 160. You need to change this to 580, or directly define PJMEDIA_SOUND_BUFFER_COUNT to 30. If you are using PJSIP 1.3 then you need to use delay buffer by defining PJMEDIA_SOUND_USE_DELAYBUF to 1 and PJMEDIA_SOUND_BUFFER_COUNT to 30 (by default it is 6) in the pjmedia/ include/pjmedia/config.h file.
