Installing and Activating Mediation Server

Communications Server 2007, Mediation Server and a third-party basic media gateway function as a single logical unit to enable communication between the users enabled for Enterprise Voice and the public switched telephone network or a Session Initiation Protocol (SIP) trunking provider. This step describes how to install and activate Mediation Server.

Mediation Server deployment is an integrated component of Office Communications Server 2007 setup. When you install and activate Mediation Server, the Microsoft Office Communications Server 2007 Deployment Tool copies the required files to a local computer, but it does not activate the service. The activation step becomes available only after installation is complete. Activation performs two tasks:

Creates Mediation Server objects in Active Directory.
Activates the domain service account on the server.

Requirements

To install or activate Mediation Server you must be a member of the RTCUniversalServerAdmins group or have been delegated to perform these tasks by a member of that group.

The hardware and software requirements in Internal Office Communications Server Component Requirementsin the Supported Topologies and Infrastructure Requirements documentation must be met.

A certificate is required.

The minimum recommended hardware configuration (for up to 125 concurrent calls or 5 T1) is as follows:

Single Processor Dual Core running at 3GHz
2GB RAM
30GB hard disk
Two network interface cards

Recommendations

Even if you enable TLS on the gateway link, two network interface cards are recommended on the Mediation Server for additional security: one card to communicate with the gateway and a separate card to communicate with the Office Communications Server internal infrastructure.
You can install Mediation Server on multiple computers, but each Mediation Server must have a corresponding basic media gateway or SIP trunk connection. If you are planning to install multiple Mediation Servers, you would do well to install and test a single Mediation Server before attempting to deploy them all.
To optimize performance, do not collocate Mediation Server with any other Communications Server 2007 R2 server role, and disable all unnecessary applications and services on the computer.
