Remote Control Mode
-------------------

In this mode RTP Proxy can be controlled from the remote machine over
network. When it is being used with SIP Express Router (SER), this allows
to force different paths for signalling (SIP) and media (RTP) streams.

The mode can be activated by starting RTP Proxy with `-s' command line
argument:

$ rtpproxy -s <proto>:<address>[:<port>]

proto can be either udp or udp6; address is either IPv4 or IPv6 local
address at which command commands should be accepted or `*' if rtpproxy
should accept commands at all local interfaces; port is UDP port,
if omitted port 22222 is used.

BEWARE: command protocol contains no security or auth measures, so that
you should be using other means to secure RTP Proxy, such as firewall or
even better a VPN between machine runing RTP Proxy and machine wich
runs a software that controls it.
