Dual Trunk Survivability

Dual Trunk Survivability is used for failover/survivability scenarios. This use case describes theconfiguration of Dual Trunk Survivability with the Mediatrix unit located in the LAN . It allows theconnection od a local PBX to a SIP service provider using an SBC, through the corporate firewall. .When Dual Trunk survivability is configured it implies that:

• The Mediatrix unit is setup as a Demarcation point.• When the primary SIP trunk fails, calls go through the secondary SIP trunk.• The Mediatrix unit may or may not register to the SIP trunk.• In fallback situations, when the primary trunk comes back online, the Mediatrix unit must wait

for a REGISTER to go through before sending the calls to the primary trunk.• The Mediatrix unit is located in the LAN, behind a Near-End NAT.

Getting Started

Steps1) Make sure the WAN network interface (either WAN, ETH1, Ethernet, Network, or ETH5

depending on your model) of your Mediatrix unit is connected to the network.2) Make sure the second Ethernet connector (either LAN, ETH2, or Computer depending on

your model) of your Mediatrix unit is connected to the computer.3) Log on to the Mediatrix unit Web interface.

Note: If you are using your Mediatrix unit for the first time, refer to its Mediatrix unit Quick Startguide.

Next StepLogging on to the Mediatrix Unit Web Interface (p. 7)

Logging on to the Mediatrix Unit Web Interface

InformationFor better performances, it is recommended to use the latest available version of Microsoft InternetExplorer, Google Chrome, or Mozilla Firefox.

Note: You may not be able to log on to the Mediatrix unit Web interface if you are using olderbrowser versions. The computer's network card must be on the same subnet as the Mediatrix unit.

Steps1) In your Web browser, enter the IP address used by your Mediatrix unit to communicate

with the Web interface.

• If your computer is connected to the Ethernet port, commonly used to be connected to theLocal Area Network (LAN), i.e. ETH2 on most devices, use the 192.168.0.10 IP address.

• If your Mediatrix unit is configured to use a DHCP server with IPv4, use the provided DHCPserver IP address.

2) Enter public as your username and leave the password field empty.

Note: The public username account has administrator rights.

Note: You can also use admin as a username and administrator as password.

3) Click Login.
