PJSIP : Nobody picked up

Hi,
Have you any ideas about “predictive dialer” ?? what are exactly its roles ?? Are there examples of free one to be integrated with Asterisk ? Or is it possible to develop such a soft? And what I need to know to be able to do that (special language, or Asterisk configs…) ?

And Thanks.

The role of a predictive dialer is to minimise a phone spammers labour costs.

Thanks david,
So is it possible to build a one and integrate it with Asterisk? and what will I need for that ?
