The Hangup command terminates a Call. If Hangup is used as the first action in a PerCL response, it does not prevent FreeClimb from answering the Call and billing your account. See the Reject command to hang up at no charge.

Nesting Rules

You cannot nest any actions within Hangup and you cannot nest Hangup within any other actions.


A caller who has spent a long time in a Queue is dequeued, advised to call back later, and then hung up on. Notice that the Hangup command in this specific example technically is redundant, because it is the last command in the PerCL script (that isn't a Terminal command). But we show it here for illustrating the syntax. Remember that a Terminal command will have an actionUrl that picks up the call after the PerCL command has executed. In this case, there is no actionUrl with Hangup or Say, and when a script with no Terminal command ends, the call is hung up.

    "Say" : {
      "text" : "The wait time is high. Please call back later."
    "Hangup" : {
      "reason" : "busy"
