In most ways, EarShot IFB will look like an ordinary computer to this network. In fact, EarShot IFB contains an
embedded computer with a Linux-based operating system and a full network protocol stack.
EarShot IFB is perfectly capable of working over most LANs, but there may be situations where a LAN is heavily
firewalled, subject to overloaded traffic conditions, or has security concerns. Better performance is possible if
EarShot IFB has its own Internet connection.
Since there may be bandwidth, firewall, and security concerns with installing EarShot IFB on a managed LAN,
it is recommended that your IT manager be consulted in these environments. The details that follow assume a
working knowledge of IT topics and network configuration.
On EarShot IFB, the single Ethernet port handles connections to your phone lines and the Toolbox configuration
interface. IP addressing can be DHCP or Static, but if you are often accessing the Toolbox interface of your
system, you will likely need to assign a Static IP address to the Primary ethernet port in order for the browsers to
find the mainframe.
EarShot IFB has a single “Status” indicator on the front panel. It reflects different colors based on the status of the
system:
• Red: No network is detected or the network is incompatible
• Blue: Network is connected and unit is in subsystem booting process
• Magenta: Network is connected and unit is fully booted but no SIP Provider is registered
• Green: Network is connected, unit is booted, SIP Provider is registered and unit is ready to receive calls
• White: Active call in progress on unit
