Hi, i have a problem, i do whose steps: 1. i use conference bridge, i have 3 media ports 2. port 1 starts to transmit to port 2 with level 0 (through pjsua_conf_connect2) 3. port 1 starts to transmit to port 3 with normal level (through pjsua_conf_connect2) 4. port 1 stops to transmit to port 2 (through pjsua_conf_discconnect) Port 3 still shold receive sound from port 1, but there is no sound. I suppose It's an error in pjmedia_conf_disconnect_port: this routine doesn't remove value in listener_adj_level. I've attached a path, it works for me
