We are using DMCC Java SDK, tested we could successfully register our client device on a extension and use Media Service and Call Info Service to capture audio stream and get some meta data.

However, when we have to add Call Control Monitoring (which should be part of the third-party call control service), the response to "addCallControlListener()"/"CSTA_MONITOR_DEVICE") is "GENERIC_OPERATION_REJECTION" (71), and from TSAPI logs, the cause value is CS0/18, and the abort type is 161. We have no luck searching this error code in Java API doc, TSAPI doc, etc. and would like see if anyone can provide some ideas on troubleshooting the issue.

We are using CM 8 and AES 8 with DMCC Java SDK v10.1.0.0.0.12

It may be that the CTI link between AE Services and Communication Manager is not in service. Execute the SAT command "status aesvcs cti-link" on Communication Manager and make sure the link is in the Established state.

Thank you very much Martin, checked that CM->AE Service CTI link was incorrect, the problem is resolved after fixing the setting.
