Hi Girish, It seems that audio capture worked fine on both device (there are logs about VAD threshold update). And it also seems that the device side still received packet from the emulator (there are logs about jitter buffer empty in any parts of the call session), please check with network capturer (e.g: wireshark) on the PC running emulator to make sure this. FYI, the old Echo Suppressor (there is new ES in the SVN) may cause one way audio impression, so please try to disable the echo suppressor. Btw, for compatibility reason, there is issue on G.722 regarding erroneous clock rate definition (mentioned in RFC 3551 Section 4.5.2) that affects RTP timestamp interval. This issue is already handled on the latest PJSIP version.
