Processes the end of a call, specifically for emailing a voicemail or sending call data to a database or a website.


  • Onrelease is an event action.
  • When a caller, agent, or the Hangup action hangs up the phone, the contact is released and the script is terminated.
  • When a caller, agent, or Hangup action hangs up the phone, and there is an Onrelease event in the script, the script will not terminate immediately, but will continue until there are no more actions that follow, or a Stop or Hangup action is executed.
  • Media - specific actions (such as Play, Menu, or Record) are not allowed after the Onrelease event. TheRunsub and Runscript actions should not be placed after the Onrelease action.
  • To process a phone call contact, CXone uses a Voice port. After a call has been released (i.e., completed), CXone uses an Other port (if one is available) to handle end of call processing. If there is not an Other port available, CXone continues to use the Voice port.
  • For troubleshooting purposes, when you run the debugger within Studio, the SS7 cause codes auto populate the _CALLRESULT, _CAUSECODE, and _CAUSECODECATEGORYID variables to indicate the reason a call was released.
  • There can be only one Onrelease event action in a script.

Result Branch Conditions

Result branch conditions allow you to create branches in your script to handle different outcomes when an action executes.
