Core Issue

In the process of upgrading, the Computer Telephony Integration (CTI) point becomes disconnected and does not connect.

Resolution

Application plug-ins extend the functionality of Cisco CallManager. In particular, the Java Telephony Application Programming Interface (JTAPI) plug-in allows a computer to host applications that access Cisco CallManager through JTAPI.

To resolve this issue, perform these steps:

  1. If you have upgraded to Cisco CallManager 3.3, you must upgrade the JTAPI client software on any application server or client workstation on which JTAPI applications are installed. 
  2. If you do not upgrade the JTAPI client, your application fails to initialize.     
  3. If you need to upgrade, download the appropriate client from the Cisco CallManager Administration. For more information, refer to the Installing the Cisco JTAPI Software section of Cisco JTAPI Installation Guide for Cisco CallManager 3.3.     

    Note: The upgraded JTAPI client software does not work with earlier releases of Cisco CallManager.  

    For information regarding the compatibility of Cisco CallManager and JTAPI versions, refer to Cisco CallManager Compatibility Matrix.  

  4. After reinstalling the plug-in and rebooting the Cisco Customer Response Applications (CRA) server, the issue is resolved.
