This series of interactive documents uses a typical head office and branch
office in order to demonstrate some common voice network configurations. This

You can use one of these methods in order to configure IPMA:
IPMA Configuration Wizard
Note: If you install IPMA for the first time, use the IPMA Configuration
Wizard. Because the IPMA Configuration Wizard automatically creates partitions
and Calling Search Spaces, you must use this method with caution. The manual
configuration method is used in this document because the IPMA is installed
on top of an existing IP Telephony network in which the Calling Search Spaces
and partitions are already configured.
In order to configure IPMA Proxy Line Support, complete these steps:
Configure Partitions and Calling Search Spaces in Unified CallManager
In order to configure partitions and Calling Search Spaces in Unified CallManager,
complete these steps:
Create the Manager and IPMA partitions as shown in
In addition, you need two Calling Search Spaces (CSS):
A CSS that includes everyone + IPMA
A CSS that includes everyone + Manager
Note: Since you adopt the Class of Restriction with Line CSS, as per
the Dial Plan document, you must utilize the current CSS at the device level
(SanJose_CSS and RTP_CSS).
In this case, add partition IPMA to both SanJose_CSS and RTP_CSS. Also,
you must ensure that the proxy line CSS and the Route Point (which is created
later) has access to the Manager partition. In this case, create another partition
Create a CTI Route Point
In order to allow the CTI Route Point to intercept calls that go to the Manager
IP Phone, you must create a directory number that is identical to the directory
number for the Manager and place it in the IPMA partition that you created in
The Calling Search Space for the CTI Route Point must have access to the Manager
Partition, as well as everyone. Create a CTI Route Point, and add a directory
number of 5001 (which is identical to the Manager directory number).
In order to create a CTI Route Point, complete these steps:
Choose Device > CTI Route Point > Add a New CTI Route Point.
The CTI Route Point Configuration page appears.
Choose SanJose_CSS_M from the Calling Search Space drop-down list.
Add the IPMA Service to the Unified CallManager IP Phone Services
In order to add IPMA service to the Unified CallManager IP phone services,
complete these steps:
Choose Feature > Cisco IP Phone Services> Add a New IP Phone Service.
Create the IPMA service under Cisco IP Phone Services in CallManager as
shown in this image:
In order to configure the IPMA Service, complete these steps:
Choose Service > Service Parameters.
The Service Parameters Configuration page appears.
Choose Cisco IP Manager Assistant from the Service drop-down list.
In the General Parameters area, enter values for these parameters:
CTI Manager (Primary) IP Address
Route Point Device Name for Proxy Mode
In the Clusterwide Parameters (Parameters that apply to all areas) area,
enter values for these parameters:
Cisco IPMA Server (Primary) IP Address
Cisco IPMA Server (Backup) IP Address
In the Clusterwide Parameters (IPMA Device Configuration Defaults for Proxy
Mode), enter values for these parameters:
All User Partition
IPMA Calling Search Space (This calling search space must include Everyone
Manager Calling Search Space (This calling search space must include
Everyone plus IPMA.)
Click the Update button located at the top of the page.
Associate the Manager and Assistant Users to IPMA
In order to associate the Manager and Assistant users to IPMA, complete these
Under CallManager, choose User > Global Directory, and search
for the user that will become the Manager and the user that will become the
Note: This examples assumes that users already exist and that the correct
device or phone is associated with the user. The user names for this example
are John Doe (Manager) and Carolyn Smith (Assistant).
Check these check boxes:
Enable CTI Application Use
Enable CTI Super Provider
Call Park Retrieval Allowed
Enable Calling Party Number Modification
On the User Configuration page, click Cisco IPMA.
Complete these steps in order to configure the Manager:
If the Manager will use Extension Mobility, check the Mobile Manager
Add Assistants as necessary.
Choose intercom lines from the Intercom Line drop-down list.
Choose the lines that will be controlled by IPMA.
Note: You can also use automatic configuration in order to configure
these parameters. However, you must first configure all the required values
under the Service
Parameters section, which adds the necessary softkey templates to your
phones. This example demonstrates how to manually configure these parameters
to ensure they are correct. Refer to
Cisco IP Manager Assistant With Proxy Line Support for
In order to configure the Assistant parameters, choose User > Global
Directory, and then search for the user that will become the Assistant.
Similarly, configure the Assistant parameters as follows:
The phone configurations are critical to the functionality of IPMA. The directory
number for the Manager (5001) must be placed in the Manager partition created
earlier in this procedure. In addition, the Calling Search Spaces for the Manager
and the Assistant must have the correct Calling Search Space assigned to their
devices. Otherwise, IPMA will not function properly.
For more information about phone configurations, see Introduction
or refer to these documents:
Choose the server, and then uncheck the Cisco IP Manager Assistant
In order to test IPMA, complete these steps:
Start the Assistant Console, and log in with the assistant user ID. In this
example, the assistant user ID is csmith.
Click Settings in order to verify that the correct server IP address
The IPMA Logon page appears.
The Cisco IPMA Assistant Console appears.
Click the Divert All check box in order to divert all calls on the
Note: You can complete this step from the Manager phone as well. Press
the More button, and then press Divert All.
Place a call to the Manager directory number, 5001.
The Assistant phone should ring on the proxy line, 5011.
On the Manager phone, press Softkey (Intercept).
The Manager phone should pick up the call. If the Manager phone does not pick
up the call, repeat the steps in this procedure in order to verify your configuration.
Note: One of the most common reasons that the Manager phone does not
intercept a call is because the calling search space is incorrect at the Assistant
phone. The Assistant phone must include a calling search space that points
to Everyone and the Manager.
