Now it?s working and streaming voice in two directions but I?ve taken some actions before. Is it my mistakes in configuration of media stream, codec and etc or pjsip bugs? Honestly, we haven't tried streamutil on Symbian ourselves. > Workarounds: > 1) ? ? ?Added stubs for pjmedia_resample_create() and pjmedia_resample_run(). There was no need for this action for Symbian S60 3rd SDK FP1. If this is about symb_aps_dev.cpp, the resample is only used by APS wrapper when working with other than 8kHz audio sampling rate, otherwise the resamplers won't be instantiated. > 2) ? ? ?Changed if statement ?in pjmedia stream.c(line 1004) because when I used AMR codec which has PJMEDIA_FRAME_TYPE_EXT ? it will never send recorded sound. > /* Encode audio frame */ > ? ?} else if (frame->type != PJMEDIA_FRAME_TYPE_NONE > ? ? ? ? ? ? ? ?/*&& frame->buf != NULL*/ ) Just realized this, and sounds like bug. We used to use audio switch board to work with PJMEDIA_FRAME_TYPE_EXT, in this case frame->buf is initialized to non-NULL. > 3) ? ? ?Changed priority selection in symb_aps_dev(line 263).
