Step 7. Configure Outbound Call Routing

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.

Configuring outbound call routing consists of instructing Communications Server how to route calls from Enterprise Voice users to phone numbers on the PSTN or a PBX. These instructions are embodied an Enterprise Voice Route. An Enterprise Voice Route consists of:

  • A unique name and optional description that identify and describe the route.

  • One or more regular expressions that specify target phone numbers that can use this route. Numbers that do not match the pattern of the target number cannot use this route.

  • One or more phone usage records that must be present in a caller's voice policy in order for that caller to place calls to target phone numbers associated with this route. If a users voice policy does not include a phone usage record associated with this route, the user is not authorized to place calls to those numbers.

  • One or more media gateways that are to be used for this route.

For detailed information about planning call routes, see Call Routes in Plan for User Authorization and Outbound Call Routing in Office Communications Server.

To create an outbound call route

  1. On a Front End Server, click Start, point to Programs, point to Administrative Tools, and click Office Communications Server 2007.

  2. Right-click the Forest node, point to Properties, and then click Voice Properties.

  3. On the Properties dialog, click the appropriate tab for the task you want to perform.

  4. On the Routes tab, click Add.


  5. In the Add Route dialog box, do the following:

    • In the Name box, type a unique name for the new call route.

    • In the Description box, type an optional description of the new call route.

    • In Target phone numbers, use .NET Framework Regular Expressions to describe the pattern of the phone numbers that are to use this route. If you need assistance, click Helper.

    • Click Add to add a media gateway or Mediation Server to the Gateways list. Only those gateways and/or Mediation Servers that have been correctly installed and configured will appear in this list.

    • Click Configure to add a phone usage record to this call route.


  6. In the Configure Phone Usage Records dialog box, select the phone usage record you want to add from the Available list, and then click the Right Arrow key (>) to add the record to the Configured list. Continue adding phone usage records as needed. When you are finished, click OK.
