Hi All, my program is designed to be able to receive two calls simultaneously (in different threads). When an inbound comes in, my program plays audio data stored in memory to the caller. It works well when there is only one inbound. However, when two inbounds come in simultaneously, the sound quality heard by both callers is so poor that can be considered as noises. When one of the inbound calls has hung up, the sound quality on the other connected inbound call becomes good again. Could someone tell me what I am doing wrong?
Thanks a lot!

My code is included as follows:
// add port of the channel and the port of the audio buffer to the conference bridge if((pjmedia_conf_add_port(*(sipChannel->getPlayConf()), //pjmedia_conf *conf, sipChannel->getPlayPool(), //pj_pool_t *pool, portChannel, //pjmedia_port *strm_port, NULL,//const pj_str_t *name, &slotChannel//unsigned *p_slot) ) == PJ_SUCCESS) && (pjmedia_conf_add_port(*(sipChannel->getPlayConf()), //pjmedia_conf *conf, sipChannel->getPlayPool(), //pj_pool_t *pool, portBuffer, //pjmedia_port *strm_port, NULL,//const pj_str_t *name, &slotBuffer//unsigned *p_slot) ) == PJ_SUCCESS) && // connect audio and channel ports (pjmedia_conf_connect_port(*(sipChannel->getPlayConf()), slotBuffer, slotChannel, 0) == PJ_SUCCESS) && (pjmedia_conf_adjust_tx_level(*(sipChannel->getPlayConf()), slotChannel, SIP_ADJUST_LEVEL) == PJ_SUCCESS) && (pjmedia_conf_adjust_rx_level(*(sipChannel->getPlayConf()), slotBuffer, SIP_ADJUST_LEVEL) == PJ_SUCCESS) && // register call back (pjmedia_mem_player_set_eof_cb(portBuffer, sipChannel, &fillPlayBuffer) == PJ_SUCCESS)) { pj_status_t status = -1; // create master port if((sipChannel->getSipStatus().compare("CONFIRMED") == 0) && (status=pjmedia_master_port_create(sipChannel->getPlayPool(), portNull, pjmedia_conf_get_master_port(*(sipChannel->getPlayConf())), 0, sipChannel->getPlayMasterPort() )) == PJ_SUCCESS) // start the master port status = pjmedia_master_port_start(*(sipChannel->getPlayMasterPort()));}
