# Call Features in the Dataphone Desktop App

This article explains how to use key in‑call features in the desktop app: **Hold, DTMF (Dial Pad), Call Transfer, Call Parking, and Conference Calls.** These features are available while you are actively on a call.

---

During a call, you can transfer a call, put a call on hold, create a conference, and much more. You can access those features by utilizing the UI components described below:

1. **Call panel**. You can access a call panel by clicking on a contact you’re currently talking to in the list of contacts, chats, or calls, or by double-clicking on an Active Line.
2. **Active lines panel**. This is where all your active calls will be displayed.
3. **Pop-up window**. This panel will automatically pop up if a contact you’re talking to is not selected in the tabs panel.
