# NAT-related stuff: specifically, you can configure the STUN/TURN
# servers to use to gather candidates if the gateway is behind a NAT,
# and srflx/relay candidates are needed. In case STUN is not enough and
# this is needed (it shouldn't), you can also configure Janus to use a
# TURN server# please notice that this does NOT refer to TURN usage in
# browsers, but in the gathering of relay candidates by Janus itself,
# e.g., if you want to limit the ports used by a Janus instance on a
# private machine. Furthermore, you can choose whether Janus should be
# configured to do full-trickle (Janus also trickles its candidates to
# users) rather than the default half-trickle (Janus supports trickle
# candidates from users, but sends its own within the SDP), and whether
# it should work in ICE-Lite mode (by default it doesn't). If libnice is
# at least 0.1.15, you can choose which ICE nomination mode to use: valid
# values are "regular" and "aggressive" (the default depends on the libnice
# version itself; if we can set it, we set aggressive nomination). If
# libnice is at least 0.1.19, you can enable consent freshness checks for
# PeerConnections as well: this will issue regular checks to check whether
# or not the WebRTC peer isn't available anymore. Enabling consent freshness
# will automatically also enable using connectivity checks as keep-alives, which
# might help detecting when a peer is no longer available (notice that
# current libnice master is breaking connections after 50 seconds when
# keepalive-conncheck is being used, so if you want to use it, better
# sticking to 0.1.18 until the issue is addressed upstream). Finally,
# you can also enable ICE-TCP support (beware that this may lead to problems
# if you do not enable ICE Lite as well), choose which interfaces should
# be used for gathering candidates.

	# You can configure a TURN server in two different ways: specifying a

	# credentials to authenticate. Notice that you should NEVER configure
	# a TURN server for Janus unless it's really what you want! If you want
	# *users* to use TURN, then you need to configure that on the client
	# side, and NOT in Janus. The following TURN configuration should ONLY

	# You enable this by specifying the address of your TURN REST API backend,
	# the HTTP method to use (GET or POST) and, if required, the API key Janus
	# must provide. The timeout can be configured in seconds, with a default of
	# 10 seconds and a minimum of 1 second. Notice that the 'opaque_id' provided
	# via Janus API will be used as the username for a specific PeerConnection

	#allow_force_relay = true

	# You can also choose which interfaces should be explicitly used by the
	# gateway for the purpose of ICE candidates gathering, thus excluding
	# others that may be available. To do so, use the 'ice_enforce_list'
	# setting and pass it a comma-separated list of interfaces or IP addresses
	# to enforce. This is especially useful if the server hosting the gateway
	# has several interfaces, and you only want a subset to be used. Any of
	# the following examples are valid:
	#     ice_enforce_list = "eth0"
	#     ice_enforce_list = "eth0,eth1"
	#     ice_enforce_list = "eth0,192.168."

	# In case you don't want to specify specific interfaces to use, but would
	# rather tell Janus to use all the available interfaces except some that
	# you don't want to involve, you can also choose which interfaces or IP
	# addresses should be excluded and ignored by the gateway for the purpose
	# of ICE candidates gathering. To do so, use the 'ice_ignore_list' setting
	# and pass it a comma-separated list of interfaces or IP addresses to
	# ignore. This is especially useful if the server hosting the gateway
	# has several interfaces you already know will not be used or will simply
	# always slow down ICE (e.g., virtual interfaces created by VMware).
	# Partial strings are supported, which means that any of the following
	# examples are valid:
	#     ice_ignore_list = "vmnet8,192.168.0.1,10.0.0.1"
	#     ice_ignore_list = "vmnet,192.168."
	# Just beware that the ICE ignore list is not used if an enforce list
	# has been configured. By default, Janus ignores all interfaces whose
	# name starts with 'vmnet', to skip VMware interfaces:
	ice_ignore_list = "vmnet"

	# In case you want to allow Janus to start even if the configured STUN or TURN
	# server is unreachable, you can set 'ignore_unreachable_ice_server' to true.
	# WARNING: We do not recommend to ignore reachability problems, particularly
	# if you run Janus in the cloud. Before enabling this flag, make sure your

# Event handlers allow you to receive live events from Janus happening

# (packets sent/received, losses, etc.) should be sent: by default it's
# once per second (audio and video statistics sent separately), but may
# considered too verbose, or you may want to limit the number of events,
# especially if you have many PeerConnections active. To change this,
# just set 'stats_period' to the number of seconds that should pass in
# between statistics for each handle. Setting it to 0 disables them (but
# not other media-related events). By default Janus sends single media
# statistic events per media (audio, video and simulcast layers as separate
# events): if you'd rather receive a single containing all media stats in a
# single array, set 'combine_media_stats' to 'true'.
