1. Introduction Administrator's Manual 1 Introduction This Administrator's Manual is intended for system administrators responsible for setting up and configuring the AudioCodes 420HD IP Phone with Microsoft Lync, in enterprise network environments. 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.
420HD IP Phone with Microsoft Lync 1.1 Deployment Overview The figure below shows how to deploy AudioCodes IP phones in an enterprise customer's network.
2. Preparing the Microsoft Lync Environment for IP Phones Administrator's Manual 2 Preparing the Microsoft Lync Environment for IP Phones Before plugging in and playing the IP phones in an enterprise's 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. b. c. d. Active Directory, LDAP service DNS service DHCP service NTP service 3. Unified Messaging Server (optional) 4.
420HD IP Phone with Microsoft Lync Correct configuration of these three is critically important. The other DHCP options shown in the figure above are also important but are less susceptible to inaccuracies than these. 2.1.1 DHCP Option 43 Option 43 comprises the five sub-options 001-005 shown in the figure above and in the table below. These point the phone to the location of the Certificate Provisioning service on the Lync server.
Administrator's Manual 2.2 2. Preparing the Microsoft Lync Environment for IP Phones Making Sure the DHCP Server is Correctly Configured for Auto Provisioning After creating a cfg configuration file (see Section 3 on page 17), 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.
420HD IP Phone with Microsoft Lync 2.3 Troubleshooting 2.3.1 Using the Phone LCD to Troubleshoot Use the table below to help troubleshoot deployment problems that can occur after preparing the enterprise network environment for IP phone deployment. Tip: Use the first phone that you deploy as an indicator for the entire deployment. If the first phone plugs in and plays without irregularities, all phones deployed after it should also.
