Cisco JTAPI Installation Guide for Cisco CallManager 4.1(2)
This document describes how to install and configure the Cisco Java Telephony API (JTAPI) client software for Cisco CallManager 4.1(2).
This document contains the following topics:
Cisco Java Telephony API (JTAPI) implementation comprises Java classes that reside on all client machines that run JTAPI applications. Installation of the Cisco JTAPI implementation must take place before applications function correctly. Make sure that the Cisco JTAPI classes are installed wherever JTAPI applications will run, whether on Cisco CallManager, on a separate machine, or on both. Installation requires 5 MB of local disk space.
Note If you have upgraded to Cisco CallManager 4.0, you must upgrade the JTAPI client software on any application server or client workstation on which JTAPI applications are installed. If you do not upgrade the JTAPI client, your application will fail to initialize. If you need to upgrade, download the appropriate client from the Cisco CallManager Administration as described in the Installing the Cisco JTAPI Software section.
The upgraded JTAPI client software does not work with older releases of Cisco CallManager.
Installing the Cisco JTAPI Software
Cisco JTAPI supports multiple languages for the installation and JTAPI preferences UI.
The Cisco JTAPI installation utility installs the following items on the local disk drive:
•JTAPI java classes in %SystemRoot%\java\lib
•JTAPI Preferences in Program Files\JTAPITools
•JTAPI sample applications (makecall, jtrace) in Program Files\JTAPITools
•JTAPI documentation in Program Files\JTAPITools\doc
Note To run JTAPI applications, you need a Java 1.1-compatible environment such as the Sun JDK 1.1.x, JDK 1.2, JDK 1.3, or Microsoft Virtual Machine (bundled with Internet Explorer 4.0 and higher). Cisco JTAPI will also run on Sun JDK1.2.
To use JTPREFS with Cisco JTAPI, however, requires the JDK 1.2 or higher environment. For information on JTPrefs, see the "Configuring Cisco JTAPI Tracing" section.
If you are installing Cisco JTAPI on a Windows 2000 workstation or server, you already have a compatible version of the Microsoft Virtual Machine. On all other Microsoft platforms such as Windows 95, Windows 98, and Windows NT, verify the current version of the Microsoft Virtual Machine by running the command "java /?" and noting the version that is printed at the top of the console.
Perform the following steps to install the Cisco JTAPI software.
Step 1 Log in to the computer where you want to install the Cisco JTAPI client software.
Step 2 Close all Windows programs.
Step 3 Open a web browser.
Step 4 Go to the Cisco CallManager Administration:
Name specifies the name or IP address of the Cisco CallManager
Step 5 Choose Application > Install Plugins.
Step 6 Choose the Cisco JTAPI link.
Step 7 Follow the instructions in the popup windows.
Note Install Cisco JTAPI software on the default drive as directed by the installation software. When Windows NT is installed in C:\WINNT, the default directory, for example, is C:\WINNT\Java\lib.
Verifying the Installation
To verify the JTAPI installation, you can use the makecall application that allows you to place a call via JTAPI. Perform the following procedure to use the makecall application.
Step 1 From the Windows NT command line, navigate to the directory where you installed Cisco JTAPI Tools. By default, this directory is C:\Program Files\JTAPITools.
Step 2 Execute the following command:
Step 3 Execute the following command:
java makecall <server name> <login> <password> 1000 <phone1> <phone2>
server name specifies the hostname or IP address of the Cisco CallManager (for example, CTISERVER).
phone1 and phone2 designate directory numbers of IP phones or virtual phones that the user controls according to the user configuration. See the Cisco CallManager Administration Guide for details.
For login and password, use the user ID and password that you configured in the Cisco CallManager User Configuration window.
You can also use the JTAPI Preferences user interface utility tool to verify the installed JTAPI version:
Go to Start > Programs > CiscoJTAPI > JTAPI Preferences.
Auto Install for Upgrades
This feature provides a facility by which an application at startup can identify itself to a Cisco CallManager web server via an HTTP request, and receives a response with the version of the required JTAPI API. The application compares the version that is available on the server to the local version in the application classpath and determines whether an upgrade is necessary.
The application makes changes in the init process to instantiate an updated API to discover the server installed component and download the component as needed.
The feature aims are allowing applications to refresh the jtapi.jar component to match the Cisco CallManager, and also a way to centrally deploy the jtapi.jar to which applications can auto update.
The API required to perform this functionality is packaged in the form of an updater.jar. jtapi.jar and updater.jar are packaged with a standard manifest that can be used to compare versions. A application does not have to resort to instantiating a Version class as this could make the API write protected from an update.
This feature, when specified with the location and component, downloads jtapi.jar from server and copies it to local directory. The application can either copy downloaded jtapi.jar with its copy by overwriting it or change the classpath to access the new jtapi.jar.
Note Auto Install does not update JTAPI preferences, TAPITestTools, updater.jar, and javadoc components. If applications require these components, install JTAPI from the Cisco CallManager plugin pages.
Configuring Cisco JTAPI Tracing
Use the Cisco JTAPI tracing preferences application (JTAPI Preferences) to configure trace levels and trace destinations. Installation of the Cisco JTAPI Preferences into the Program Files\JTAPITools directory utility takes place by default. To open the Cisco JTAPI Preferences utility, choose Start > Programs > Cisco JTAPI > JTAPI Preferences.
This section, which describes how to use the Cisco JTAPI preferences application, discusses the following topics:
Figure 1 illustrates the Trace Levels tab of the Cisco JTAPI preferences application. The window title shows the JTAPI version number.
Figure 1 Trace Levels Tab
The Trace Level tab allows you to enable or disable the following JTAPI trace levels:
•WARNING—Low-level warning events
•DEBUG—Highest level debugging events
You may enable or disable additional debugging levels in the Debug Levels window, as described in the following list:
•JTAPI_DEBUGGING—JTAPI methods and events trace
•JTAPI_IMPLDEBUGGING—Internal JTAPI implementation trace
•CTI_DEBUGGING—Trace Cisco CallManager events that are sent to the JTAPI implementation
•CTIIMPL_DEBUGGING—Internal CTICLIENT implementation trace
•PROTOCOL_DEBUGGING—Full CTI protocol decoding
•MISC_DEBUGGING—Miscellaneous low-level debug trace
Figure 2 illustrates the Log Destination tab of the Cisco JTAPI preferences application.
Figure 2 Log Destination Tab
The Log Destination tab allows you to configure how JTAPI creates traces and how they are stored. Table 1 contains descriptions of the log destination fields.
Figure 3 illustrates the Cisco CallManager tab of the Cisco JTAPI preferences application.
Figure 3 CallManager Tab
This tab allows you to define a list of Cisco CallManagers that a JTAPI application can present to the user for optional Cisco CallManager connectivity.
Figure 4 illustrates the Advanced tab of the Cisco JTAPI preferences application.
Figure 4 Advanced Tab
You can configure the parameters in Table 2 through the Advanced tab in the JTPrefs application. You may need these low-level parameters for troubleshooting and debugging purposes only.
Note Cisco recommends that you not modify the parameters in Table 2 unless the Cisco Technical Assistance Center (TAC) instructs you to do so.
The Language tab allows you to select one of the installed languages to view the configuration settings in that language.
Choose a language and click Change Language to reload the tabs with the text in that language.
JTAPI Preferences on non-Microsoft environments
For non-Microsoft environments, you must create a jtapi.ini file manually and place it in the CLASSPATH. The following list provides the parameter names with sample values:PROTOCOL_DEBUGGING=0UseSameDirectory=1JTAPIIMPL_DEBUGGING=0UseSystemDotOut=0QueueStatsEnabled=0PeriodicWakeupInterval=50RouteSelectTimeout=5000UseTraceFile=0ProviderOpenRequestTimeout=30Directory=DEBUG=0DesiredServerHeartbeatInterval=30AlarmServicePort=1444CTI_DEBUGGING=0SyslogCollector=JTAPI_DEBUGGING=0PeriodicWakeupEnabled=0NumTraceFiles=10AlarmServiceHostname=MISC_DEBUGGING=0TracePath=.UseAlarmService=0CTIIMPL_DEBUGGING=0WARNING=0Traces=WARNING;INFORMATIONAL;DEBUGINFORMATIONAL=0UseSyslog=0CtiPortAutoRecovery=1FileNameBase=CiscoJtapiCtiRequestTimeout=15TraceFileSize=1048576Debugging=JTAPI_DEBUGGING;JTAPIIMPL_DEBUGGING;CTI_DEBUGGING;CTIIMPL_DEBUGGING;PROTOCOL_DEBUGGING;MISC_DEBUGGINGFileNameExtension=logQueueSizeThreshold=25ProviderRetryInterval=30CallManagers=cm1SyslogCollectorUDPPort=514UseProgressAsDisconnectedDuringErrorEnabled=0AllowNetworkEventsAfterOffered=0
Administering User Information for JTAPI Applications
The JTAPI application requires that users be administered in the directory and given the privilege to control one or more devices. Follow the procedures for adding a user and assigning devices to a user in the "Adding a New User" section before using the JTAPI application. The list of devices assigned to the user represents the phones that the user needs to control from the application (for example, make calls and answer calls).
