Configuration Note 1. Introduction
Version 1.0 Issue 1.0 9 October 2011
1 Introduction
This Configuration Guide describes a sample configuration scenario for a network that
uses the AudioCodes Mediant 800 MSBG E-SBC, Mediant 1000 MSBG E–SBC or the
Mediant 3000 E-SBC Media Gateway to facilitate a connection between Microsoft
Lync 2010 and PATEC’s SIP Trunking Service, for superior voice quality services.
The Mediant 800 MSBG E-SBC is a networking device that combines multiple service
functions such as a Media Gateway, Session Border Controller (SBC), Data Router
and Firewall, LAN switch, WAN access, Stand Alone Survivability (SAS) and an
integrated general-purpose server.
The Mediant 1000 MSBG E-SBC is all-in-one multi-service access solution products
for Service Providers offering managed services and distributed Enterprises seeking
integrated services. This multi-service business gateway is designed to provide
converged Voice & Data services for business customers at wire speed, while
maintaining SLA parameters for superior voice quality.
The device is based on AudioCodes’ VoIPerfect Media Gateway technology,
combined with Enterprise class Session Border Controller, Data & Voice security
elements, Data Routing, LAN Switching and WAN Access. These services allow
smooth connectivity to cloud services, while providing protection to the end customer.
The Mediant 3000 E-SBC Media Gateway is a High Availability VoIP Gateway and
Enterprise Class SBC for medium and large enterprises.

2 Testing Considerations
Note that for the PAETEC test environment:
Fax was not tested
G.711 U-law and G.729 were the codecs tested for this application
Voice mail was not tested during the certification but it functions

Configuration Note 3. Configuration Scenario Overview
Version 1.0 Issue 1.0 13 October 2011
3 Configuration Scenario Overview
The configuration scenario described in this guide includes:
An enterprise has deployed a Microsoft® Lync server 2010 in its private network
for enhanced communication within the company.
The enterprise decides to offer its employees VoIP and to connect the company
to the PSTN using the PAETEC SIP Trunking Service.
Setup requirements are:
While the Microsoft® Lync Server 2010 environment is located on the enterprise's
Local Area Network (LAN), the PAETEC SIP Trunk is located on the WAN.
Microsoft® Lync Server 2010 works with the TCP or TLS transport type, while the
PAETEC SIP Trunk works on the SIP over UDP transport type.
Microsoft® Lync Server 2010 supports G.711 - µ Law coder type while PAETEC
SIP Trunk supports the G.729 and G.711- µ Law coder types.
Support for early media handling
Support for call forwarding
Support of Gateway Registration
Figure 3-1 overviews the configuration scenario.

Configuration Note 4. Configuring Microsoft Lync Server 2010
Version 1.0 Issue 1.0 15 October 2011
4 Configuring Microsoft Lync Server 2010
This section describes how to configure the Microsoft Lync Server 2010 to operate
with the E-SBC device.
¾To do this:
1. Configure the E-SBC device as an ‘IP/PSTN Gateway’
(see Section 4.1 on page 16)
2. Associate the ‘IP/PSTN Gateway’ with the Mediation Server
(see Section 4.2 on page 21)
3. Configure a ‘Route’ to utilize the SIP trunk connected to the E-SBC device
(see Section 4.3 on page 27)
Note: Dial Plans, Voice Policies, and PSTN usages are also necessary for
enterprise voice deployment; however, they are beyond the scope of this
document.

4.1 Configuring AudioCodes’ E-SBC Device as
‘IP/PSTN Gateway’
This section describes how to configure the AudioCodes E-SBC device as an
IP/PSTN Gateway.
Note: The Microsoft Lync Topology Builder interface dialogs refer to the E-SBC
device as an ‘IP/PSTN gateway’ or ‘PSTN gateway’.
¾To configure the E-SBC device as an IP/PSTN Gateway and associate it with
the Mediation Server:
1. On the server where the Topology Builder is located, start the Microsoft Lync
Server 2010 Topology Builder: Click Start, select All Programs,then select
Lync Server Topology Builder.

Version 1.0 Issue 1.0 17 October 2011
The following screen is displayed:
Figure 4-2: Topology Builder Options
2. Choose ‘Download Topology from the existing deployment’ and click OK.
You are prompted to save the Topology which you have downloaded.

3. Enter a new File Name and Save - this action enables you to roll back from any
changes you make during the installation.
The Topology Builder screen with the downloaded topology is displayed.

4. Expand the Site; right-click on the IP/PSTN Gateway and choose ‘New IP/PSTN
Gateway’.

Figure 4-6: Define New IP/PSTN Gateway
5. Enter the FQDN of the E-SBC device (i.e., ‘E-SBC.OCSW14.local’) and click OK.
Note that the listening port for the Gateway is ‘5060’ and the transport type is
‘TCP’. In certification testing for the PAETEC SIP Trunk, listening port 5060 was
used with transport protocol ‘UDP’. To configure the E-SBC with the datafill in
order to interface PAETEC, see Configuring the E-SBC Device.
The E-SBC device is now added as an ‘IP/PSTN Gateway’.
