This video will provide the steps to set up Fax Over IP failover IP addressing with RightFax.

There are 2 different ways you can go about setting up a failover IP address for RightFax to use with Fax Over IP integration.
The first is by using dialing rules
You will create 2 dialing rules each appending the IP address of the gateway you wish to route your FOIP calls through.
Enable the rule for the primary IP and give it a higher weight value than the rule using the secondary gateway IP for FOIP.
Now you just need to add a registry value to enable the failover to occur automatically.
1.Open the Windows Registry Editor (regedit).
2.Browse to the following registry subkey that is appropriate for your operating system.
32-bit Windows  HKEY_LOCAL_MACHINESOFTWARERightFaxDocTransportTransportsBrooktrout
64-bit Windows  HKEY_LOCAL_MACHINESOFTWAREWOW6432NodeRightFaxDocTransportTransportsBrooktrout
3.Add a new DWORD value, as follows:
Name  DisableDialingRuleOnTimeout
Value  1
4.Close the Windows Registry Editor.
5.Restart the RightFax DocTransport service.
Remember, if you need to revert back to the original configuration, you will need to go back in to your dialing rules and re-enable the rule with the primary gateway IP.
The second method is via the Dialogic Brooktrout Configuration Tool.
1.In the Doctransport configuration, select the Configure Brooktrout option.
2.Configure your IP stack to the IP Call Control Protocol used in your network.
3.Verify that "Dynamic routing by a Proxy server" is selected.
4.Configure any additional proxy servers. In this example, the proxy server is the next hub in your network.
5.Click Save and Apply.
This method will work for the original Dialogic SR140 as well as the RightFax OEM SR140.
That's all for configuring Fax Over IP failover IP addressing with RightFax.
