Administrator's Manual 1. Introduction
Version 2.0.11 11 400HD Series IP Phone with Microsoft Lync
1 Introduction
This Administrator's Manual is intended for administrators responsible for provisioning
AudioCodes' 400HD Series of IP Phones deployed with Microsoft Lync in an enterprise
network.
AudioCodes IP phones are based on AudioCodes' proprietary High Definition (HD) voice
technology, providing clarity and a rich audio experience in Voice-over-IP (VoIP) calls.
The phones are fully-featured telephones that provide voice communication over an IP
network, allowing you to place and receive phone calls, put calls on hold, transfer calls, etc.
The phones offer different automatic provisioning options.
This manual shows how to automatically provision a mass deployment of AudioCodes IP
phones using DHCP.

Administrator's Manual 2. Automatic Mass Provisioning of IP Phones using DHCP
Version 2.0.11 13 400HD Series IP Phone with Microsoft Lync
2 Automatic Mass Provisioning of IP
Phones using DHCP
This section shows how to automatically provision a mass deployment of AudioCodes IP
phones in a Microsoft Lync environment.
Note: Instead of using DHCP as the automatic provisioning method, you can
alternatively use Static DNS Record or SIP SUBSCRIBE and NOTIFY messages (see
Appendix A).
As DHCP clients, AudioCodes IP phones can be automatically provisioned with the
following files:
„
Configuration file (.cfg)
„
Firmware file (.img)
These files can be placed on any of these three provisioning server types:
„
HTTP/S server
„
TFTP server
„
FTP server
Figure 2-1 summarizes the steps required for setting up mass provisioning of IP phones in
the Microsoft Lync environment.
These steps are described in detail in the following sections.
Note: Automatic mass provisioning of IP phones using the DHCP provisioning method
can alternatively be performed from the AudioCodes EMS Provisioning Server in the IP
Phones Management Server. For detailed information, see the IP Phone Management
Server Administrator's Manual.

Figure 2-1: Setting up Automatic Provisioning
Prepare the Microsoft Lync environment for IP phones,
e.g., configure the DHCP server with DHCP Option 160 to
point to the provisioning server’s URL
Without signing in, save a single phone’s default
configuration as a .cfg file, using the Web interface

3
Configure this single phone to perform according to your
specific performance requirements in the enterprise
4
Save the phone’s newly configured settings as a .cfg file
5
Create a configuration .cfg file containing only the delta
between the default .cfg and the newly configured
enterprise-specific .cfg file

Place the delta .cfg file on the provisioning server
Load this delta .cfg file to another phone. Sign in.
Test performance to see if it matches requirements.
Connect all IP phones to the network and power up.

Administrator's Manual 2. Automatic Mass Provisioning of IP Phones using DHCP
Version 2.0.11 15 400HD Series IP Phone with Microsoft Lync
2.1 Preparing the Microsoft Lync Environment for IP
Phones
Before plugging in and playing the IP phones in an enterprise's Microsoft Lync
environment, make sure that the environment is ready for them.
To prepare it for IP phones, you must set up:
1. Front End Lync Server
2. Domain Controller, including:
a. Active Directory, LDAP service
b. DNS service
c. DHCP service
d. NTP service (optional)
3. Unified Messaging Server (optional)
4. Mediant™Gateway
5. SBA Server (optional)
For details, refer to Microsoft's website at:

Version 2.0.11 17 400HD Series IP Phone with Microsoft Lync
2.1.1.2 DHCP Option 120
Option 120, which includes the Lync Server’s fully qualified domain name (FQDN) as
shown in the table below, is required for the certification authority (CA) pool Registrar.
Use the table as reference to make sure Option 120 is correctly configured.
Table 2-2: DHCP Option 120 Configuration Reference
Option Number Option Name ASCII Value (example)
120 UCSipServer lyncserver.domain.com
2.1.1.3 DHCP Option 42
Option 42 specifies the servers that provide NTP /SNTP for the network. Make sure that
NTP server IP addresses are correct, as shown in the table below.
Table 2-3: DHCP Option 120 Configuration Reference
Option Number Option Name String (example)
42 NTP Servers 10.59.0.20, 10.59.0.21
2.1.2 Making Sure the DHCP Server is Correctly Configured for Auto
Provisioning
After creating a .cfg configuration file (see Section 2.2), place it - and the software file (img)
and other files such as tone files - on a provisioning server from where the IP phones can
download and install it.
To get the URLs to this provisioning server, the IP phones use DHCP. The provisioning
server can be HTTP/S, TFTP or FTP server.
The phone features automatic update capability to update the configuration and the
software. Checks for newer configuration files and software versions are routinely
automatically performed. Manual checks can also be performed.
¾To make sure the feature functions correctly:
1. Verify that the provisioning server is running and that the configuration and firmware
files are located in the correct location on it.
2. Connect the phone to the IP network and then to power.
3. On the DHCP server, configure DHCP Option 160 with the URL to the provisioning
server where the configuration and firmware files are located.
By default, the IP phone uses Option 160 which has highest priority.
If absent, the IP phone uses Options 66/67 for TFTP.
The following syntax is available for DHCP option 160:
x<protocol>://<server IP address or host name>/<firmware file
name>;<configuration file name>
x<protocol>://<server IP address or host name>
x<protocol>://<server IP address or host name>/<firmware file name>
x<protocol>://<server IP address or host name>/;<configuration file name>
Where <protocol> can be "ftp", "tftp", "http" or "https"
4. During DHCP negotiation, the phone requests DHCP options 66/67/160 to receive
provisioning information. The DHCP server responds with Option 160 providing the
provisioning URL, or Options 66 and 67 providing the TFTP IP address and firmware
file name respectively.

5. The phone then checks whether new firmware is available by checking the firmware
file header. If the version is different from the one currently running on it, the phone
downloads the complete image and burns it to its flash memory.
6. If new firmware is unavailable, the phone checks whether a new configuration file is
available on the server. If available, the phone downloads it and updates the phone’s
configuration after verifying that the configuration file is related to the phone model.
When a configuration update is needed, the phone might reboot.
Notes:
ƒOnly img (firmware) and cfg (configuration) files can be used.
ƒIn the DHCP Discover message, the phone publishes its model name in Option
fields 60 and 77 (e.g., 420HD). To provide different provisioning information to
different models, set up a policy in the DHCP server according to phone model
name.
ƒIf the phone is powered off during provisioning, it becomes unusable; perform a
recovery process (see Section 5 on page 107).
