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

Table 1. User Policy

Default Calling Policy

International

Table 2. Routes

Route name Number pattern Phone usage Gateway

Redmond Local Route

^\+1(425|206|253)(\d{7})$

Local

Red-GW1

Red-GW2

Dallas Local Route

^\+1(972|214|469)(\d{7})$

Local

Dallas-GW1

Universal Route

^\+?(\d*)$

GlobalPSTNHopoff

Red-GW1

Red-GW2

Dallas-GW1

Intl Route

^\+([2-9])(\d*)$

International

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 Default Calling Policy.

  • A new route, Intl Route, is introduced, which matches a number that starts with +2 through +9 (international to the United States) and has a phone usage of International.
