Assuming that a few users from Redmond, Dallas, and New York are being enabled for Enterprise Voice, here is a sample definition of a phone usages and routes that enable a very basic routing setup.

Note:
The phone usage name used in the following examples omits spaces, but this is a matter of taste or convention. Spaces are valid for phone usage names.

Table 1. Sample Definition of Phone Usages

User policy	Phone usage
Default Calling Policy	GlobalPSTNHopoff

Table 2. Sample Definition of Phone Usages

Route name	Number pattern	Phone usage	Gateway
Universal Route	^\+?(\d*)$	GlobalPSTNHopoff	Red-GW1 Red-GW2 Dallas-GW1

Route name

Phone usage

Gateway

Universal Route

^\+?(\d*)$

GlobalPSTNHopoff

Red-GW1

Red-GW2

Dallas-GW1

In the previous example, all the users who are being enabled for Enterprise Voice in the three sites are assigned a policy of DefaultCallingPolicy.
The illustrated route is configured to direct all calls from users with a phone usage of GlobalPSTNHopoff (users with DefaultCallingPolicy, in this example) to one of three gateways (the \+? indicates that the leading + is optional).
