Media Relay: Determines the behavior adopted by the NAT traversal
feature when it detects that two remote (i.e. far-end) NATed endpoints
report the same public IP address. When in aggressive mode, a media
relay will be used to carry the media between the two endpoints. When
conservative is used, endpoints will be instructed to stream their
media directly to each other.


Though I doubt the aggressive setting will work with every scenario.
Do not assume STUN is there to do anything OTHER than to allow the
system to discover its IP address (when dynamic ip is used). The
recommended setting for remote users is to not use stun, and to turn
off any ALG or sip helper applications, including ICE, STUN, and let
them connect to sipx. The aggressive media relay setting may not work
reliably in every remote user scenario.

This is where a commercial sbc would typically be deployed.
