Determine the Number and Distribution of Users

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.

The total number of users to be enabled for Enterprise Voice is less important than the distribution of users among the locations where your organization conducts business.

For each location, you will need to:

  • Determine valid dialing patterns for each location and create location profiles consisting of normalization rules that convert those patterns to E.164 format.

  • Estimate call traffic and decide on the size, number, and location of the media gateways that will be required. See Plan for Media Gateways.

  • Enable users for Enterprise Voice and create voice policies that specify the types of calls various individuals and user groups are allowed to make.
