Pega Call provides an Agents rule (in the Pega-CTI ruleset) that periodically performs various tasks.

By default, the agent runs once every 120 seconds and does one or more of the following:

• Starts CTI links that are configured to AutoStart. For more information on configuring CTI links to start automatically, see the chapter Configuring a CTI link on Pega.
• Purges older call objects.
