2

Purpose

This guide is for configuring the necessary options for interconnecting NET’s UX2000 SBC between XO’s

SIP Trunk offerings and Microsoft’s Lync Server 2010 over the public internet. The UX2000 provides a

secure method of isolating the internal corporate data network from the publicly reachable SIP Trunk

offerings. The UX2000 is located between the Public Internet and the internal WAN/LAN network as

shown below:
