Have you tried to turn off the VAD (set media_cfg.no_vad = PJ_TRUE)?
If the problem still occurs, try to use G711 codec.

> # define PJMEDIA_HAS_G711_PLC 0
> # define PJMEDIA_HAS_L16_CODEC 0
> # define PJMEDIA_HAS_GSM_CODEC 1
> # define PJMEDIA_HAS_ILBC_CODEC 0
> # define PJMEDIA_HAS_SPEEX_CODEC 0
> # define PJMEDIA_HAS_SPEEX_AEC 0
> # undef PJMEDIA_RESAMPLE_IMP
> # define PJMEDIA_RESAMPLE_IMP PJMEDIA_RESAMPLE_LIBRESAMPLE
> # define PJMEDIA_WSOLA_IMP PJMEDIA_WSOLA_IMP_NULL
> # define PJMEDIA_HAS_SRTP 0
> WireShark indicates that GSM codecs are used in both directions.
> Not sure where to look next. Suggestions?
