Installing the Agent for IP Office Centralized Voicemail
The UC server can also work as a centralized voicemail in an IP Office environment. The corporate office
configuration for centralized voicemail is the same as a single-site IP Office deployment, and each branch
IP Office is configured the same way as the corporate IP Office. Branch IP Offices use a locally configured
group of extensions that are redirected to the main IP Office location.
Each branch office requires you to install an agent application that you can configure remotely using UC
server. The agent application redirects incoming voicemail calls to the centralized UC server. The
redirected call includes all the information needed to answer the call correctly.
The agent operates as follows:
• Listens for calls forwarded to voicemail hunt groups at the remote site through TAPI messages.
• When a call is forwarded to the remote site voicemail hunt group, the agent then does two things:
• Sends the call party information along with a unique call identifier to the UC server running at the
corporate site using TCP/IP.
• Redirects the call to the corporate site IP Office voicemail hunt group.
• The corporate site IP Office then forwards the call to UC server, which then handles the call as if it had
been placed to an extension at the corporate office site.
When you install and configure the branch IP Office, follow the same steps as the installation of the
corporate or main IP Office. To configure IP Office, you need to know the following:
The Avaya MERLIN MAGIX CTI link requires you to install the following:
•Eicon card
• CenterVu Software
• MMPD PBX driver software
• Refer to the Integrating Merlin Magix PBX technical note available online at

.
Avaya IP Office requires you to install the CTI link Pro software in third-party mode. Refer
to the Integrating IP Office technical note available online at http://kb.adtran.com
.
To ensure that UC server can correctly identify the associated mailbox for each forwarded
call and for the message waiting light to work properly, all extensions in the corporate and
branch offices must be unique. An extension number that is used at any site must not be used
again anywhere else.
Agent IP address The IP address of the agent computer.
