The DialingPredictProvider property tells sample management which dialing component to use for predictive dialing. The PredictScript property contains the script that the component is to use to make the predictions. Default values for your site are defined in the site-level DefaultDialingPredict property collection. When a project is activated, the site defaults are copied into the project's sample management object and then apply only to that project.

The DialingSync property in SampleManagements>ProjectName is set to 1 if anything is added to or changed in the sample management's DialingPredictProvider property collection. This then causes the property collection to be loaded into DPM so that the changes become available to new calls.

In version 4.5 there is no activity that can change the properties in this collection, although you could change them manually. You would then have to add the DialingSync property to DPM to have your changes implemented.

The StatisticsSync property controls the statistics that the group dialing provider uses to decide how many numbers it should be dialing at a time, and the current percentage of silent calls. The property does not appear in DPM until a supervisor clicks the Reset Statistics button on the Dialer Settings tab in the Interviewing Options activity. This increments the value of StatisticsSync which, in turn, causes the dialing statistics and the percentage of silent calls to be reset to zero. The value of this property is checked once every five seconds.
