Default Value Description
Specifies the STUN (Session Traversal Utilities for NAT) server IP
address or name to use to determine if the phone is behind a NAT,
the type of NAT, and the public address of the phone. The field can
contain a comma separated list of servers. Each server can be a
domain name, host name, or IP address, and it may contain an
optional port number. (For STUN see IETF RFC 5389.)
0 Enables the use of the ICE (Interactive Connectivity Establishment)
protocol for NAT traversal. ICE takes advantage of STUN and TURN
to identify candidates (IP addresses and ports) for communication,
evaluating and prioritizing the candidate pairs to select the best
route. Expensive candidates, such as using a media relay, are
selected only as a last resort. (For ICE see IETF RFC 5245.)
1 ICE nomination method. When using ICE, select the preferred ICE
Nomination Method. To validate candidate pairs (IP addresses and
ports for the local and remote nodes), CS-700 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, CS-700 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, CS-
700 does not 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.
5 Maximum number of ICE host candidate. An ICE host candidate is
an actual local transport address in the host. Host transport
addresses are obtained by binding to attached 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
