# callUUIDToGroupWith

The unique identifier of the call to be grouped with the call associated with the receiver.

```
var callUUIDToGroupWith: UUID? { get set }
```

## Discussion

If `nil`, the call associated with the receiver leaves any group it’s currently a member of.

If the call associated with the receiver is already in a group, the call should first leave that group, if necessary.
