Nanang, > Just recalled that we also have problems with APS/VAS G729, e.g: > ticket #735 (http://trac.pjsip.org/repos/ticket/735). So the APS/VAS > G729 behaviour will be: > - G.729 encoder always disables VAD, so no SID/DTX frames will be generated. > - G.729 decoder will be able to handle SID/DTX frames (when VAD is enabled). Thank you for those clarifications. Regards, Vikram.
