Verint Recorder has been configured to AES. Where AES is monitoring the devices.
Under the Security --> Security Database, the CTI user was properly configured on the AES end.
Under the Security --> Security Database --> Device Groups --> There are specific extensions which have been marked to monitor and record.
But under Security --> Security Database --> Devices there Device IDs are confired TLink was set to NONE. This is the reason why the Monitoring is Rejecting.
Change this to ANY and test the CTI connectivity.
