Due to lower negotiated international calling rates from a particular site, administrators might want to configure all international calls from US to route out of a particular gateway, the following configuration illustrates how all international calls are routed via Red-GW1.

Though there are different ways to implement regular expression patterns, the previous example shows a sample configuration.

  • A phone usage of International is added to the policy.

  • An Intl route is introduced that matches a number that starts with +2 through +9 (international to the US), and has a phone usage of international.
