Explanation
The CallSubflow step and the Trigger Application step are two Cisco Unified CCX steps that can invoke another Cisco Unified CCX application script. The CallSubflow step allows a script to call another script as a subflow, which can return values to the calling script. The Trigger Application step allows a script to trigger another application by using one of its associated triggers, which can be either a Unified CM Telephony trigger or an HTTP trigger. Both steps can be used to modularize the script logic and reuse existing scripts.
