I am trying to port simpleua example in symbian with VAS direct. The
invite session is fine and call get connected but problem with media.
Player and Recorder is created but failed when media playing. Looks
like frame buffer had not been initialized. It fails in play_cb
function in soundport.c and PlayCbPcm function in symb_vas_dev.cpp
where I get data abort exception.

Any idea what am I missing.

    const pjmedia_sdp_session *remote_sdp;
    pjmedia_port *media_port;

    if (status != PJ_SUCCESS) {

	app_perror(THIS_FILE, "SDP negotiation has failed", status);
	return;
