	remote nodes), FLX sends STUN binding requests as part of the
	media connectivity tests. When a candidate is nominated for use, a
	STUN binding request is sent with a flag indicating that the
	candidate pair is nominated. There are two nomination methods that
	can be used:
	Regular – For Regular Nomination, FLX validates candidate pairs
	with initial STUN binding requests, and then selects a valid
	candidate pair by sending another STUN binding request with a flag
	indicating that the pair is nominated.
	Aggressive – For Aggressive Nomination, FLX doesn’t wait to set
	the nominated flag in a second STUN binding request, but rather
	sets the flag in the STUN binding requests for all of the candidate
	pairs. The ICE processing completes when the first pair successfully
	passes connectivity checks. The aggressive method is faster but
	does not always result in the optimal path being selected. This is the
	default method.
Maximum	An ICE host candidate is an actual local transport address in the
number of ICE	host. Host transport addresses are obtained by binding to attached
host candidates	network interfaces. These interfaces include both physical interfaces
	and virtual interfaces such as VPN. This option specifies the
	maximum number of local ICE host candidates that may be used in
	evaluating candidate pairs when determining the best route. The
	default value is -1 or an empty field, which indicates that there is no
	maximum.
Disable RTCP	Select this option to disable the RTCP component in ICE. The

Enable TURN	Select this option to enable the use of a TURN (Traversal Using
relay with ICE	Relay NAT) relay when using ICE. A TURN relay is a media relay
	server residing on the public internet which can relay media data
	packet between clients. TURN relays are used when other preferred
	mechanisms are not available, such as STUN or direct connectivity.
	The option is unchecked by default. If TURN is enabled, the TURN
	settings below (server, username and password) must also be
	specified.
TURN Server	Specify the TURN server domain name or hostname. The format is
	either "DOMAIN:PORT" or "HOST:PORT"
TURN Username	Specify the username to authenticate against the TURN server.
TURN Password	Specify the password to authenticate against the TURN server.
Use TCP	Use TCP to communicate with the TURN server rather than UDP.
