Field Description
Firewall Traversal
IP Address This setting controls how your IP address is presented.
• Discover global address: Let Bria determine your public IP address. This is
the recommended setting unless your VoIP service provider advises
otherwise.
• Use local IP address: use the IP address of the Bria computer.
The recommended setting is Discover global address.
STUN Server This setting specifies the STUN server to use.
• Discover the server: Choose this option to let Bria find the address of a STUN
server.
• Use specified server: To use a different STUN server. For the address enter a
domain name or an IP address.
The recommended setting is Discover server.
Enable ICE ICE optimizes traffic and may help with firewall traversal.
Typically, ICE is enabled. However, it may need to be disabled if your VoIP
service provider has implemented a firewall traversal solution that is not
compatible with ICE enabled.
If you have problems with calls, contact your service provider for information on
their firewall traversal solution.
Port Used on Local Computer
Manually specify range 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.
