Configuring Call Authorizations

Configuring call authorization consists of defining phone usage records and Voice policies.

Phone usage recordsare named classes of calls that specify which call routes a user is authorized to use, facilitating enforcement of both dialing authorization and route utilization. Phone usage records are similar to what in traditional telephony is known as "class of service," but phone usage records offer greater flexibility because they are applied to both users and routes, making it possible to formulate very precise phone authorizations for both individuals and groups. You specify a phone usage record as an arbitrary label that enables you to identify a category of call destinations. You can name phone usage records whatever you like, but the names should be easily recognizable. For example, typical phone usage records might include "Local," "Area Code," "State," "Province," "USA," "Singapore," and "International." After you create phone usage records, you assign them to both policies and routes. Planning phone usage records consists primarily of listing all the current call permissions for your organization, and then determining the permissions for which to create phone usage records. Phone usage records are assigned to both routes and users for the purposes of specifying call authorization. A single user can have many phone usage records. Phone usage records provide a quick, simple way to assign call permissions to users as well as facilitate route prioritization and selection. By assigning phone usage records to both user policies and outbound call routes, you indicate which users are allowed to make calls that utilize particular routes.
Policiesare named sets of phone usage records. Policies are used to assign call privileges to users. They also specify whether endpoint devices are enabled for simultaneous ringing. When you deployed Enterprise Voice, you specified at least one Voice policy. You can change the global policy (the Enterprise Voice policy that applies to all users) used for the forest by selecting a specific policy to be used as the global policy or specifying that the policy is to be specified on a per-user basis. If you chose to apply policies on a per-user basis, you can create multiple policies and assign each, as appropriate, to specific individuals or groups of users. If you specify a global policy that applies to all users, not a per-user policy, you cannot assign additional policies on a per-user basis.

If a policy associated with a user account contains one or more phone usage records that match a phone usage record that is associated with a specific route, the user is authorized to initiate calls that use that route.

The order in which you create phone usage records does not matter, but the order in which you assign them to Voice policies is significant, because the server traverses the phone usage records in the Voice policies from top to bottom. For best performance, the phone usage records in each policy should be ordered top to bottom from most to least widely preferred. For example: RedmondLocal, RedmondLongDist, RedmondInternational, RedmondBackup.

Note:
The recommended way of creating a Voice policy is to create the appropriate phone usage records first, and then create the policy and add the appropriate phone usage records. As an alternative, you can create one or more policies and add the phone usage records later. However, if you forget to add the phone usage records and then apply the policy to one or more users, the policy has no effect.

Before you configure call authorizations for your organization, you should be familiar with phone usage records, policies, and planning call authorizations. For details about these features, see Planning for Voicein the Planning and Architecture documentation.

To create a phone usage record

On a Front End Server that has the Office Communications Server 2007 R2 administrative tools installed, open the Office Communications Server 2007 R2 snap-in.
In the console tree, right-click the Forestnode, point to Properties, and then click Voice Properties.
Click the Phone Usagestab.
On the Phone Usagestab, click Addto create a new phone usage record.
In the Add Phone Usage Recorddialog box, do the following:
- In Name, type a clear, descriptive, unique name for the phone usage record, for example, Local Long-Distance Stockholm, Internal Only, International. You can use any name you like, up to 256 Unicode characters. The name can contain spaces.
- In Description, optionally, describe the phone usage record in more detail.

To create a Voice policy

On a Front End Server that has the Office Communications Server 2007 R2 administrative tools installed, open the Office Communications Server 2007 R2 snap-in.
In the console tree, right-click the Forestnode, point to Properties, and then click Voice Properties.
Click the Policytab.
On the Policytab, click Add.
In the Add Policydialog box, in Policy name, type a name.
To enable simultaneous ringing of phones for this policy, select the Allow simultaneous ringing of phonescheck box. This enables each user to configure Office Communicator such that incoming calls, in addition to ringing the user's registered endpoints, also ring an additional nonregistered endpoint, such as a personal mobile phone. To disable simultaneous ringing, clear the check box. Normally, simultaneous ringing should be enabled, but in the event of excessive congestion, you can disable this feature
To add a phone usage record to the policy, click Configure.
In the Configure Phone Usage Recordsdialog box, do the following:
- To add a phone usage record to the Configuredlist, click the phone usage record in the Availablelist, and then click the right arrow.
- To remove a phone usage record from the Configuredlist, click it, and then click the left arrow.
- To move a phone usage record up or down in the Configuredlist, click it, and then click Up and Down.
When you are finished, click OK. The phone usages you added now appear in the list of Phone usage recordsin the Add Policyor Edit Policydialog boxes.

To specify a global Voice policy

On a Front End Server that has the Office Communications Server 2007 R2 administrative tools installed, open the Office Communications Server 2007 R2 snap-in.
In the console tree, right-click the Forestnode, point to Properties, and then click Voice Properties.
On the Policytab, in the Global policydrop-down list, do one of the following:
- To use a single policy for all users, click the name of the policy.
- To apply individual policies for specific users, click Use per user policy.
