Using the Correct Gateway for Local Calls

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

Extending the previous simple example, if administrators would like to configure the routes so that calls that are local to the context of the gateway are routed via that gateway, and other calls are routed through any of the gateways, the following configuration enables that scenario.

  • All users are assigned the Default Calling Policy.

  • The policy has 2 phone usage attributes, Local and GlobalPSTNHopoff. For any number dialed by users with this policy, a route matching the Local phone usage attribute is sought first before trying to match a route with the GlobalPSTNHopoff phone usage attribute.

  • Redmond Local Route: This route will be used for calls made to a number that starts with +1 followed by either 425, 206, or 253, followed by 7-digits, for users with a phone usage of Local.

  • Dallas Local Route: This route will be used for calls made to a number that starts with +1 followed by either 972, 214, 469, or 817, followed by 7-digits, for users with a phone usage of Local.

Examples:

  • Calls made to +1425555 0100 are routed using either Red-GW1 or Red-GW2 (Redmond Local Route).

  • Calls made to +1214555 0100 are routed using Dallas-GW1 (Dallas Local Route).

  • Calls made to +1203555 0100 are routed using either Red-GW1, Red-GW2, or Dallas-GW1 (Universal Route).

  • If Dallas-GW1 is unavailable, calls made to +1214555 0100 are routed using the Universal Route (based on using the globalPSTNHopoff phone usage).
