XTunnels
Use XTunnels The appropriate setting depends on whether your VoIP service provider has an XTunnels server.
• Automatic: Use Xtunnels when Bria detects a firewall that prohibits communications. This is the
recommended setting if your service provider has an XTunnels server.
• Always: Always use XTunnels.
• Never: Do not use XTunnels. This is the correct setting if your service provider does not have an
XTunnels server.
Server Address Optionally, specify the name or IP address of the XTunnels server to use.
• If the field is completed, Bria will use that server.
• If it is blank, Bria will perform a DNS lookup to discover the server.
Username and Password Check this box to use the username and password from your SIP account in order to log into the
XTunnels server.
Otherwise, uncheck this box and complete the Username and Password fields.
Range of Ports on Local Computer
Range of ports used on
local computer The appropriate setting depends on your computer setup:
• Checked: If your computer is behind a restrictive firewall that only allows specific port ranges to
be used. Enter the range of ports to use for your SIP account. (You must also open those ports on
your firewall; refer to applicable firewall documentation for information.)
• Unchecked: If your computer is not behind a restrictive firewall.
