Chapter 4: Managing Enterprise Voice

Communications Server 2007

The Office Communications Server 2007 Administrative Tools enable you to accomplish the following Enterprise Voice management tasks:

  • Configure global and pool settings for Enterprise Voice.
  • Configure settings for a single Standard Edition Server functioning as a pool or for the Office Communications Server 2007, Mediation Server.
  • Configure your Enterprise Voice infrastructure for routing calls among Enterprise Voice users and to numbers managed by a legacy PBX users and the PSTN.
  • Specify route-based user call authorizations.
  • Enable and configure users for Enterprise Voice.

The Office Communications Server 2007 administrative snap-in for MMC is installed by default on all Communications Servers. In addition, you can install the tools separately on a computer from which you want to manage Communications Servers remotely.

You can run the Office Communications Server 2007 Administrative Tools on the following operating systems:

    Global settings include the following:

    • Location profiles specify which normalization rules apply to calls from a particular locale. To create, edit, or remove location profiles, see Step 2. Create Location Profiles.
    • Phone usage records define user calling privileges. A single policy may include multiple phone usage records. To create, edit, or remove phone usage records, see Step 6. Configure Call Authorization.
    • Policies specify which phone usage records apply to which users. They also specify whether endpoint devices are enabled for simultaneous ringing. To create, edit, or remove voice policies, see Step 6. Configure Call Authorization.
    • Routes define how calls are routed through the Enterprise Voice infrastructure. A route consists of a target telephone number, one or more media gateways that are designated to handle that number, and the phone usage records that a user must have for permission to call the target number. To create, edit, or remove a route, see Step 7. Configure Outbound Call Routing.

The Office Communications Server 2007 Enterprise Pool, or a Standard Edition Server functioning as a pool, must be configured with a location profile. The location profile translates dialed numbers into E.164 format for reverse number look-up and call routing.

In addition to specifying a location profile for the pool or home server, you can also configure settings for the Microsoft Office Communicator Phone Edition.

  1. Open the Front End Properties page for a chosen pool or server, and then click the Voice tab.

  2. Select the default location profile, and then click View to review the contents of the location profile. If the location profile is not the one you want, continue viewing additional location profiles until you find it If the location profile you want does not exist, you must create a new one (for details, see Step 2. Create Location Profiles).

  3. Click OK.

  1. Open the Front End Properties page for a chosen pool or server, and then click the Voice tab.

  2. Click Enforce phone lock.

    Table 11. Valid ranges for PIN length and timeout length

    PIN Length Timeout Length (in minutes)

    4 through 15 characters; default 6

    0 through 60 minutes; default 10

  4. Click OK.

  1. Open the Front End Properties page for a chosen pool or server, and then click the Voice tab.

  2. Click Configure.

  3. In the Advanced Voice Options dialog, accept the default values for QoS and 801.2p Voice or type new values. Acceptable value ranges are shown in the following table:

    Table 12. Valid ranges for QoS and 801.2 Voice

    Voice Option Range of Values

    QoS

    0 through 63; default 40

    801.2 Voice

    0 through 7; default 5

  4. Click OK.

    Click Help for information about the settings for the SIP security modes.
  4. Click OK.

A Mediation Server must be able to pass SIP requests and media between the Enterprise Voice infrastructure and a media gateway connected to the PSTN. This requires configuring the following settings:

  • The IP address used to listen for calls.
  • The name of the Audio/Video Access Edge Server that will host the A/V Authentication Service for this Mediation Server.
  • The location profile to be used by the Mediation Server.
  • The port range for media exchange.
  • The FQDN and TLS port of the internal next hop server used by this Mediation Server.
  • The FQDN and TCP port of the media (PSTN) gateway used by this Mediation Server.
  • To configure a mediation server, see Configure Mediation Server in Step 5. Deploy a Media Gateway.

From time to time you may need to take a Mediation Server offline for purposes of maintenance or replacement. Care must be taken in deactivating a Mediation Server because if you simply remove it from service without first taking precautionary steps, you will cause any active calls to be dropped. There are three ways to safely deactivate a mediation server:

  • Deactivate the Mediation Server on the weekend or holiday, or in the middle of the night, but only after you have checked the call logs to make sure nobody is using that particular gateway.
  • Change routes on the Office Communications Server so that no new calls are routed through the Mediation Server to be activated. Then wait for all calls to hang up.
  • A combination of the first two options in which you change routes on the Office Communications Server during off-hours, after all calls have completed.

Office Communications Server 2007 uses the CDR (Call Detail Records) infrastructure to capture Enterprise Voice call details.

Bb803648.note(en-us,office.12).gifNote:
Before you administer call detail recording, you must first install an Archiving Server and all its prerequisites as well as enable call detail recording according to the instructions in the Microsoft Office Communications Server 2007 Archiving and CDR Server Deployment Guide. Also ensure that you have enabled archiving according to the instructions in the "Enable Archiving" section of this document.

  1. Log on to a server in the forest where you installed Communications Server 2007 that has the Office Communications Server, Administration Tools installed using an account in the RTCUniversalServerAdmins group.
