This example extends the example in Source-Based Routing. In this case, an administrator wants to define a failover route that can be used in case the Dallas-GW1 is brought down for maintenance, or is unavailable. The following tables illustrate the required configuration change.

  • In the previous example, a phone usage of GlobalPSTNHopoff is added after the DallasUsers phone usage in the Dallas Calling Policy.

  • This enables calls with the Dallas Calling policy to use routes that are configured for the GlobalPSTNHopoff phone usage if a route for the DallasUsers phone usage is unavailable.
