The Callout BIC-based BICs have been implemented for common functions and are detailed in the subsections below. Each BIC can be selected in the automatic activity selection list in Design Console. A graphical icon will represent what the callout does vs. the green double-gears that is displayed for the Callout BIC. Each individual Callout BICs has its own thread pool (the default is 100 maximum threads), so a high-volume of work items at one BIC of a specific type won't prevent any new work items at a different BIC from being processed.
