The problem might be caused by one of the following:
Cisco Unified CM is not running.
Incorrect JTAPI client version is installed on the Cisco Unified CCX server.
JTAPI user is not configured correctly.
JTAPI client cannot communicate with the Cisco Unified CM.
Recommended Action
Depending upon the cause, do one of the following:
Troubleshoot the Cisco Unified CM (refer to Cisco Unified Communications Manager Administration Guide).
Check the JTAPI version on the Cisco Unified CCX server by selecting Start > Programs > Cisco JTAPI > Readme.
From the Cisco Unified CCX Administration web page, choose Subsystems > JTAPI, click the JTAPI Provider hyperlink, and then verify that information in the User ID field matches the name of a valid user in Cisco Unified CM. Verify that information in the Password field is correct.
Verify that Cisco Unified CM is running. Configure Cisco Unified CM using the IP address instead of the DNS name.
