• -i: the listening interface for RTP/SRTP
• -n: the listening IP and port that is used by OpenSIPS to communicate with the RTPengine (NOTE: the rtpengine module only works with the rtpengine NG protocol, so you must use -n/--listen-ng; Using -u/--listen-udp or -l/--listen-tcp will not work!)
• -c: the IP and port of the CLI - this is used to gather statistics for the RTP/SRTP sessions
• -m, -M: both take an integer as argument and together define the local port range from which rtpengine will allocate UDP ports for media traffic relay. Default to 30000 and 40000 respectively.
• -L: indicates the debugging level
