The Parameters settings allow you to specify the amount of time to wait before re-dialing numbers that are busy, unanswered, or answered by an answering machine.

You set these parameters at the start of the project, and can change them throughout the interviewing period to match the current requirements of the survey. For example, if it is the last day of the survey and you are running low on new participants, you might want to increase the maximum number of times that numbers may be called. You might also want to reduce the elapse times for automatically set appointments so that numbers with callbacks become available for recall more quickly.

The table allows you to define the amount of time to wait before attempting to re-dial samples that meet a specific criteria (no answer, busy, and so on). Enter appropriate values (in minutes) for each call category.

When selected, the interviewer who arranged the appointment is given preference over other available interviewers (as it applies to scheduling when samples can be retried). If the project uses group/predictive autodialing, the interviewer will not be connected automatically to the participant who has an appointment. Instead, the participant's details are displayed on the interviewer's screen, and the interviewer must then click the Start Dialing button to dial the participant's phone number.

When selected, any available interviewer is allowed to retry the sample, regardless of who arranged the appointment. This is the default setting.

The number of minutes before the recall time that a number with an automatic appointment can be called. The default is ten minutes.

The time zones in which participants are located. The values that you enter in this field must be the indexes of the time zones in the list of time zones stored in the registry. If more than one time zone is specified, the numbers must be separated by semicolons. If this property is blank, UNICOM Intelligence Interviewer - Server Admin will ignore time zone and calling times when selecting records for interviewers to call.

When selected, calls are assigned to interviewers based on interviewer qualifications. For example, if the participant's native language is Spanish, then assign the call to a Spanish speaking interviewer.
