[SR-Users] Kamailio RTP proxy require?

[Sergio Charrua]

Another example of when to use RTPProxy / RTPEngine is:

SIP user -> router -> INTERNET -> router / firewall -> Kamailio (private
IP) -> Asterisk (private IP)

Apart from the routers, all other equipments are private IPs, hence being
NATed and requiring RTP Proxy / RTP Engine to forward RTP streams to the
correct ports.
As David Vilasmil points out, security wise, this is the best approach....
but it is a PITA configuring and making all the services work correctly.
