Hi Ayman, Did you notice any possibility of both devices were echoing each other? Try to physically separate them, e.g: put them in different room, and lower both speaker volume, or just put on their handsfree/headset, this can avoid audio loop e.g: from speaker of device 1 to mic of device 2 sent via RTP to device 1 then played on the speaker of device 1 and so on. If the noise is gone but you still experience half duplex call, then you can disable echo suppression as in my previous mail. Echo suppression works based on the VAD.
