Which two Cisco Unified CCX steps invoke another Cisco Unified CCX application script?

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. References: Cisco Unified Contact Center Express Editor Step Reference Guide, Release 12.0(1) - Call Subflow Step 1 and Trigger Application Step 2
