ortp 예제 테스트 어떻게 해야하나요?

아래소스는 ortp 예제 test소스인데요
실행방법은
usage: rtpsend filename dest_ip4addr dest_port [ --with-clockslide ] [ --with-jitter ]
이렇게 명시하고 있는데요

아래소스를 분석해보고자 테스트실행을 해볼려고하는데 실행명령을 위의 방법으로 해야 할것 같은데
./rrtsend test.txt 호스트ip dest_port [ --with-clockslide ] [ --with-jitter ]
dest_port부터의 명령을 뭐라고 입력을 해야 하나요?
