Hi All I'm using streamutil with broadcasting in subset such as 192.168.100.255. when two system is working such as A with this IP address 192.168.100.1 and B with this ip address 192.168.100.2. both of them try to bradcast to 192.168.100.255. both of them can send and receive. I try to join other node such as 192.168.100.3 in streamutil receiver mode. the Voice is going to be noisy, I think when the 3rd node receives the RTP packet RTCP packets sends RTCP packet to those computers and this cause the voice in A and B to be metalized. I know the IETF strongly recommended to use RTCP but I need disable RTCP generally in all node or in a single node. anybody has experience with this feature or not, what are the effects in this test scenario. Best Regards Abbas
