Main difference to native Red5-Phone project
The main difference with the Red5Phone is that red5sip runs not
through Red5, but as a jsvc daemon. It uses red5.jar for connecting to
Red5 as a client.
The second point that audio flows from each Openmeetings room's
participants connected to Red5 are multiplexed and transmitted to the
SIP server through a single connection.
