1. Introduction

These Application notes provide instructions on how to configure Local Survivable Processor (LSP) with the Juniper VF 3000 SBC in an Avaya Hosted IP Telephony (HIPT) R3.0 Solution Environment. The solution described in this document requires the addition of an extra network element, a Network Address Translation (NAT) device at the edge of the service provider’s data center if customers with LSPs are to be supported. This document covers the configuration of the NAT device, as well as the other components of the solution.

2.1. On Demand Solutions

The Session Border Controller (SBC) function is an essential component of the two Avaya On Demand/Hosted offers. The base offers for the Avaya HIPT R3.0/3.1 and Hosted Contact Center (HCC) R3.0 will make use of the Juniper VF 3000 SBC from the Juniper VF-Series product line. The Juniper VF 3000 SBC provides the Application Layer Gateway (ALG) and Network Address Translation (NAT) functions for the Avaya VoIP network components. The Juniper VF 3000 SBC is deployed at the service provider’s data center and is shared amongst multiple enterprise customers. The Juniper VF 3000 SBC segregates incoming traffic from different customers and forwards the traffic to the associated Avaya Communication Manager. All communication from components (i.e. endpoints, and media gateways) that passes through the Juniper VF 3000 SBC will appear to Avaya Communication Manager as having a Juniper VF 3000 SBC IP address. These components also see Avaya Communication Manager as having a Juniper VF 3000 SBC IP address. The Juniper VF 3000 SBC acts as a proxy in both directions. The side of the Juniper VF 3000 SBC that is exposed to the Wide Area Network (WAN) is often referred to as the “outside” interface – the untrusted side. The other side, the “inside” interface, is the trusted side and is exposed to Avaya Communication Manager and the data center network.

Figure 1 shows the high-level network architecture for a typical Avaya On Demand/Hosted solution. The data center is owned and operated by the service provider. In this case the hosts in the data center are in a private address space owned and managed by the service provider. The individual customer networks include Avaya G250, G350 and G700 H.248 Media Gateways and H.323 phones at the enterprise sites. The media gateways may include a Local Survivable Processor (LSP) to support local survivability. The enterprise site is characterized by a private IP address space owned and managed by the enterprise customer. Although not shown in the diagram, each enterprise customer could have multiple, diversely located sites, any or all of which may have MGs and LSPs in addition to endpoints. The IP address spaces in these sites are independent, and could overlap. Transport between the enterprise sites and the data center in this example occurs over the public addressed WAN. A NAT function is therefore required at the
