Core Issue
There are installations of Personal Assistant (PA), AC and Cisco Emergency Responder (CER), which now bundle the Java Telephony Application Programming Interface (JTAPI) version. You need to check that version.
Example:
Install the Cisco CallManager Attendant Console. It installs and uses its own local jtapi.jar file.
This is the directory of C:\Program Files\Cisco\Call Manager Attendant Console\lib:
04/28/2004 12:55p <DIR> .
04/28/2004 12:55p <DIR> ..
11/06/2003 01:20p 650,280 ac.jar
11/06/2003 01:20p 206,289 crimson.jar
07/15/2003 08:02a 753,209 jtapi.jar
11/06/2003 01:20p 352,668 log4j.jar
Resolution
To find out the version of the jtapi.jar file, set the jtapi.jar classpath and then type java CiscoJtapiVersion.
For example:
C:\Program Files\Cisco\Call Manager Attendant Console\lib>java -cp .\jtapi.jar CiscoJtapiVersion
Cisco JTAPI Version 1.4(3.8) Release
