Account Properties – Presence
Presence allows remote parties to view a local user’s online status (availability), and allows the local user to see
the online status of others. Once users have configured presence settings under this tab, they can set up various
privacy rules to customize their published availability (see “Availability” on
page 22 and “Privacy Rules” on
page 25 ).

Field Description
IP Address This setting controls how X-Lite presents IP addresses.
• Discover global address: lets X-Lite determine the user’s public IP address. This
is the recommended setting unless a VoIP service provider advises otherwise.
• Use local IP address: uses the internal IP address of the computer running X-Lite.
STUN Discovery This setting specifies the STUN server that X-Lite should use.
• Discover the server: select this option to let X-Lite find the address of an
appropriate STUN server. This is the recommended setting.
• Use specified server: compels X-Lite to use a different STUN server (enter a
domain name or IP address in the text field).
Enable ICE ICE optimizes traffic and may help with firewall traversal.
Typically, ICE is enabled, but may need to be disabled if a VoIP service provider has
implemented a firewall traversal solution that is not compatible with ICE.
For firewall-related problems with calls, contact the appropriate service provider for
information about their firewall traversal solution.
Manually specify port range Appropriate settings depend on the user’s computer setup:
• Checked: the computer running X-Lite is located behind a restrictive firewall that
only allows specific port ranges to be used for communication. Enter the range of
ports to use for the SIP account (open those ports on any firewall device as well).
Refer to applicable firewall documentation for details.
• Unchecked: the computer running X-Lite is not located behind a restrictive
firewall.
Use XTunnels Appropriate settings for XTunnels depend on whether the account’s VoIP service
provider uses an XTunnels server.
• Automatic: uses XTunnels when X-Lite detects a firewall that prohibits
communication. This is the recommended setting if the account’s service provider
uses an XTunnels server.
• Always: compels X-Lite to always use XTunnels.
• Never: compels X-Lite to never use XTunnels. This is the correct setting for
accounts whose service provider does not use an XTunnels server.
Use user login and password Check this box to use the username and password from the SIP account to log in to the
XTunnels server.
Leaving this box unchecked forces users to enter appropriate information in the
Username and Password fields each time an XTunnels server prompts for such
information.
