Installation and Maintenance Manual 1. Introduction
Version 1.0.1xx 9 Microsoft Teams
1 Introduction
This document provides step-by-step instructions on installing and configuring AudioCodes
Direct Routing Survivable Branch Appliances (DR-SBA) application running on AudioCodes
Mediant 800/Mediant 1000 SBA or as Virtual Appliance DR-SBA with Mediant VE/CE SBC.
Note:This document is applicable to Teams only.
1.1 Overview
Mediant SBA (referred to as the device in this document) is an essential element for
multi/single-site deployments of Teams and is fully certified by Microsoft. the device
provides branch/HQ office Site (HQ/branch) voice calling resiliency, during Wide Area
Network (WAN) failure scenarios where loss of connectivity occurs with Teams Cloud
Service. During survivability, the device maintains local call connectivity call (Dial a Number)
among Microsoft Teams users located at the site and provide call connectivity between the
users and the PSTN (SIP/E1/T1 Trunk or FXS/O) during a WAN failure (E1/T1 if interfaces
are ordered with the device).
Figure 1-1: DR-SBA at Branch Office in Teams Environment
AudioCodes offer the follow devices:
Mediant 800B DR-SBA
Mediant 800C DR-SBA
Mediant 1000B DR-SBA
Virtual Appliance DR-SBA
Mediant 800B, Mediant 800C and Mediant 1000B are 1U chassis, providing Microsoft Teams
resiliency as well as optional, PSTN Gateway and Session Border Controller (SBC)
capabilities. It also provides optional, direct connectivity to Analog Devices through
customer-ordered Foreign exchange Station (FXS) port interfaces.
The device provides an embedded, Web-based management tool called SBA Management
Interface, for installing and configuring the SBA functionality. The tool also provides a setup
wizard, which allows for quick-and-easy initial SBA installation.
AudioCodes can also offer UMP solution to manage the Users Teams Policies (as Teams
Branch Survivability Policy) as well as LifeCycle management.
The SBA application is installed on a generic single-board computer module housed in the
device chassis. The module name is Open Solution Network (OSN) and enables hosting of

Installation and Maintenance Manual 10 LTRT-33443
Mediant SBA
multiple third-party applications. The SBA application runs on Windows Server 2019
operating system.
The OSN module provides three or five network interface cards (NIC) according to the
hardware type:
Two or Four "external" NICs (RJ-45 connectors) on the OSN module’s back panel of
the Mediant 800/Mediant 1000. Ethernet port #1 and Ethernet port #2 create a
teaming interface and it is enabled by default (192.168.0.20). The external NIC is used
to connect to the SBA application from your network. This connection also allows you
to connect to the local SBC/Gateway.
One "internal" NIC connects to the internal chassis switch. This NIC is enabled and
DHCP-client enabled. The internal NIC like the external is used to connect to the SBA
application from your network. This connection also allows you to connect to the local
SBC/Gateway.
Note: Installation of any third-party software, except that which is included in the Mediant
Mediant 800/Mediant 1000 DR-SBA package purchased from AudioCodes, on the device's
OSN server must first be approved by AudioCodes.
Note: The SBA Skype for Business image also includes AudioCodes Auto-Attendant
Interactive Voice Response (IVR) and Fax Server applications, offering a 90-
day trial
license period for each application. For more information, go to
https://www.AudioCodes.com/solutions-products/products/products-for-microsoft-
365/voice-applications.
1.2 Main Benefits
The device offers the following main benefits:
Ensure uninterrupted Teams voice calls for HQ and branch offices
Secured SIP trunk connectivity with an embedded qualified E-SBC
Hosting communications-enabled business processes (CEBP) applications such as
call recording, Auto-Attendant, Fax Server (according to the Platform)
PSTN connectivity in parallel and as fallback to SIP Trunk connectivity
Full modularity and interface flexibility, including digital spans, analog ports and BRI
interfaces
Fully interoperability with AudioCodes SBC’s, supports emergency calling standards,
including E911/ ELIN and Local Media Optimization (LMO)
