FPAC Linux routing question

Do any of you on the list run FPAC Linux? I am trying to figure out how to set up alternate routing, we are moving our DOS FPAC systems to Linux but I have not been able to find a clear example of how to set up alternate routing in the Linux version.

In the DOS version the line
Route to Nodes a4bcd a4efg
would cause the routing the first try to route down the first call, if it failed it would try the second and any following, but I do not see how that is set up under Linux FPAC.
