Introduction This document describes some of the requirements and guidelines to configure Cisco CallManager in a Cisco IP Contact Center (IPCC) environment.
Prerequisites Requirements Cisco recommends that you have knowledge of these topics: • Cisco CallManager Administration
Components Used The information in this document is based on these software and hardware versions: • Cisco IPCC • Cisco CallManager versions 3.0 and later The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
Conventions Refer to Cisco Technical Tips Conventions for more information on document conventions.
ACD Lines An Automated Call Distribution (ACD) line is an extension (directory number) that is under the control of Cisco CallManager, which automatically distributes calls based on a predefined set of rules. An ACD line is used for business purposes. The Call Waiting parameter under the Directory Number Settings section in the Directory Number Configuration screen can be set to Off, On, or Default. When you configure an ACD line, you must set the value to Off (see Figure 1). You must point the Forward Busy parameter under the Call Forward and Pickup Settings section in the Directory Number Configuration screen to an alternative directory number in case the ACD line is busy (see Figure 1). Figure 1 Set the Call Waiting and Forward Busy Parameters
CTI Route Point A computer telephony integration (CTI) route point designates a virtual device that can receive multiple, simultaneous calls for application−controlled redirection. When you configure a CTI route point, Cisco recommends that you redirect Forward Busy, Forward No Answer, and Forward On Failure in the Call Forward and Pickup Settings section on the Directory Number Configuration screen (see Figure 2). Figure 2 Redirect Forward Busy, Forward No Answer, and Forward On Failure
Private Lines When you configure a private line (directory number), you must set the Call Waiting parameter under the Directory Number Settings section in the Directory Number Configuration screen to On (see Figure 3). Figure 3 Turn On the Call Waiting Parameter
Recovery Method on CTI Manager Service Cisco recommends that you set the recovery method of the Cisco Message Interface task to Restart the Service for First failure, Second failure, and Subsequent failures. In order to do so, complete these steps: 1. Start Microsoft Windows 2000 Services Manager. In order to open Services, click Start > Programs > Administrative Tools > Services. 2. Right−click Cisco Message Interface, and select Properties from the shortcut menu. The Cisco Message Interface Properties screen appears. 3. Select the Recovery tab. 4. Select Restart the Service from the First Failure, Second Failure, and Subsequent Failures lists (see Figure 4). Figure 4 Set the 'Restart the Service' Option for All Failures
5. Click Apply. 6. Click OK.
Phone Registration All phones have to register with CallManager. A phone can be registered through automatic registration, manual configuration, or the Bulk Administration Tool (BAT). Note: For security reasons, automatic registration is turned off by default.
Device Limitation on the CallManager The capabilities of the Cisco CallManager are based on the available CPU and memory resources. Each configured device has a "weight", which consumes a set amount of these resources. Devices such as gateways, conference resources, voice mail, and other applications consume device units based on their relative device weights. This table lists the weights for various devices: Device IP phone DS0 port Transcoding resource Conference resource TAPE JTAPI
Weight 1 3 3 3 20 20
The total device units of all devices configured cannot exceed the maximum device units that the Cisco Media Convergence Server (MCS) can support. The maximum device units that the MCS can support depends on the server model. The Cisco MCS 7835−1000 supports up to 5000 device units.
World Wide Web Publishing Service Cisco does not recommend that you run Web Publishing on CallManager. In order to disable Web Publishing, complete these steps: 1. Start the Microsoft Windows 2000 Services Manager. In order to open Services, click Start > Programs > Administrative Tools > Services. 2. Right−click World Wide Web Publishing Service, and select Properties. 3. In the General tab, select Disabled in the Startup type field (see Figure 5). Figure 5 Disable Web Publishing
4. Click Apply. 5. Click OK.
