new option: --local-ip This IP address will be used during pjmedia_transport_udp_create2(). default value use 0.0.0.0 I tested it with --local-ip=224.0.0.1. The strange thing was, that it worked with recv-only, but when streamutil is started in send-recv mode, I can not hear the audio. I also have added PJMEDIA_UDP_NO_SRC_ADDR_CHECKING but without success. regards klaus -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
