Quick Installation Guide 1. Introduction

1 Introduction

This guide provides step-by-step instructions for quickly setting up AudioCodes' MediaPack (MP-118 and MP-114) Session Initiation Protocol (SIP) voice-over-IP (VoIP) gateways for intermediating between third-party, private branch exchanges (PBX) or various Public Switched Telephone Network (PSTN) interfaces, and Microsoft® Office Communications Server 2007 (Office Communications Server 2007). For further information regarding Office Communications Server 2007, refer to Microsoft's Web site (http://www.microsoft.com/uc).

The figure below illustrates a network architecture with a PBX. In this scenario, the AudioCodes' gateway connects to the PBX using analog lines (FXO), and to Office Communications Server 2007 through Microsoft® Mediation Server (Mediation Server) on the IP network. The MediaPack gateways ensure interoperability with leading, third-party PBXs.

The figure below illustrates a network architecture that provides a direct connection to the PSTN network. In this scenario, the AudioCodes' gateway connects to PSTN using analog lines. At the other end, the gateway connects to Office Communications Server 2007 through Mediation Server on the IP network.
