# Allow Callers to Dial Extensions via IVR

An IVR (Interactive Voice Response) is the automated menu that answers a call and offers spoken options, such as "Press 1 for Sales." It is a helpful front door for first-time callers, guiding them to the right person or team through a series of prompts. Regular callers, though, often already know the extension they want, and sitting through the menu just to get there wastes their time. Cloud Voice lets you allow those callers to key in an extension number straight from the IVR, skipping the prompts entirely.

:::note
When a caller keys in digits during the menu, the phone sends DTMF (Dual-Tone Multi-Frequency) tones, the same touch-tone signals a keypad produces. The IVR listens for those tones, matches them to an extension, and transfers the call.

## Before you begin

Callers can only use this shortcut if they know it is available. Update your IVR greeting so it tells callers they can dial an extension number at any time during the menu.

:::tip
Word the greeting so the shortcut comes early, for example: "If you know your party's extension, you may dial it at any time." Callers who use it never have to hear the rest of the options.

## Enable direct extension dialing

1. Sign in to the phone system web portal and open **Call Features > IVR**, then edit the IVR you want to change.
2. In the **Prompt** drop-down, choose the greeting you updated to mention direct dialing.
3. In the **Dial Extensions** drop-down, decide which extensions callers are allowed to reach:
   - **All Extensions**: Callers can dial any extension on the system.
   - **Allowed Extensions**: Callers can dial only the extensions you select.
   - **Restricted Extensions**: Callers can dial any extension except the ones you exclude.

   :::caution
   **All Extensions** exposes every extension to outside callers, including private, executive, or system extensions you may not want reachable from the menu. Where possible, use **Allowed Extensions** to publish only the numbers meant for external callers, or **Restricted Extensions** to block the sensitive ones.

4. Click **Save**, then **Apply** to put the change into effect.

   :::caution
   The new setting does not go live until you click **Apply**. Saving alone stores the change but leaves callers using the old behavior.
