The prefix rule-set is loaded from the database into a binary - tree in memory, either on startup or when issuing the "prefix_route.reload" RPC - command. When calling the "prefix_route()" function from the ser.cfg - configuration script, it will try to match the user part of the request URI - with the best matching route. If a route is found, it will be used for - further processing. If not found normal processing will continue. + Telio Telecom + Copyright © 2007 Alfred E.
