It could be that the maximum number of file descriptors allowed for the
process has been reached. You can try executing "ulimit -n 60000" before
starting the RTP proxy daemon. Just a guess. In any case, the daemon
should log an error if it fails to open or allocate a port. If it
doesn't, you can try hooking into the running process with strace to see
what's going on.
