Why go out over a slow link to ask how to route when you could do any
number of lookups locally on the machine. You could write your lookup
logic into the dialplan. You could write your lookup logic into an AGI
script. You could do just about any lookups possible without the need to
go remote, but if you had to go remote, then thats easy too.
