UNICOM Intelligence Interviewer defines the preview feature as displaying a record to the interviewer before it is dialed. Interviewers who are previewing should not be available to take a group dialed call. The UNICOM Intelligence Dialer dialing provider handles this by making one request for a preview record before adding the interviewer to the group.

The dialing provider can request a preview record by setting the interview property GroupDial = 0 in the PropertiesXml parameter to ISampleManagementProvider.Get. The default sample management script then searches for records with comments or with the RequiresManualDial sample field set to True. The default sample management script will set the AutoDial sample field or AutoDial interview property to 0 if it returns a record that meets the preview requirements. Records that are returned from ISampleManagementProvider.Get with AutoDial = 0 should be returned to the session engine without dialing.

Once the interviewer has been added to the group, the interviewer property GroupDial should be greater than 0. The default sample management script will then filter out records with comments or when RequiresManualDial is set to True.

The interviewer will manually initiate dialing for a previewed record. In UNICOM Intelligence Interviewer, it is expected that the interviewer will hear the call progress (including ringing) and will then manually select a return code for the record. The interviewer will then request another contact.
