Administrator's Manual 3. Manual Configuration of a Single IP Phone
Version 2.0.11 61 400HD Series IP Phone with Microsoft Lync
3.4.3 Managing Security Certificates
AudioCodes IP phones are loaded with factory-set preinstalled certificate files: private key
file, certificate file and a Trusted Root CA file that is signed by AudioCodes.
Whenever the IP phone authenticates with a remote server, it can be authenticated using
these certificate files. Each IP phone receives a uniquely generated private key certificate
file based on its MAC address. If the remote server is configured to authenticate the client
and AudioCodes factory-set certificates are used for authentication, then the AudioCodes
Certificate and AudioCodes Trusted Root CA must be downloaded to the remote server.
These files can be downloaded from the AudioCodes Web site. For more information,
contact your local AudioCodes sales representative. If you use the AudioCodes Redirect
server to obtain firmware and configuration files, then the factory-set certificates are used
to authenticate the connection with this server. If default certificate files are missing or
deleted, the phone will regenerate these files automatically the next time it is powered up.
3.4.3.1 Loading the Root CA Certificate to the Phone
The section shows how to load the root CA certificate to the phone. The certificate enables
signing in with 802.1x Authentication. With Microsoft Lync, more than one certificate file is
loaded automatically using DHCP Option 43.

To load the root CA certificate to the phone:
1. Open the Root CA Certificate page (Configuration tab > Security menu > Root
CA Certificate).
