# CXSetHeldCallAction

An encapsulation of the act of placing a call on hold or removing a call from hold.

## Declaration

```swift
class CXSetHeldCallAction
```

## Overview

Overview CXSetHeldCallAction is a concrete subclass of CXCallAction. When a caller places a call on hold, callers are unable to communicate with one another until the holding caller removes the call from hold. Placing a call on hold doesn’t end the call. When the user or the system places a call on hold, the provider sends provider(_:perform:) to its delegate. The provider’s delegate calls the fulfill() method to indicate that the action was successfully performed.
