Set the Webphone desktop app as the default app for phone links (`tel:` links) in Windows. Clicking a phone number on a web page, in an email or in another app then opens the Webphone with the number filled in, ready to call.

## Before you start

Install the Webphone desktop app and sign in. See [Sign in to the Webphone for the first time](https://kb.voipcloud.online/phones-and-apps/webphone/webphone-first-sign-in/).

The app registers itself in Windows as **Webphone** for `TEL`, `CALLTO`, `SIP` and `SMS` links. You still choose it as the default in Windows settings.

## Steps

1. In the Webphone, go to **Settings** › **General** and turn on **Set as a default system app for calls and SMS**. The app shows where to go in Windows settings.
2. Open the Windows default apps by link type:
   - **Windows 11:** **Settings** › **Apps** › **Default apps** › **Choose defaults by link type**.
   - **Windows 10:** **Settings** › **Apps** › **Default apps** › **Choose default apps by protocol**.
3. Find **TEL**.
4. Click the app shown next to it, or **Choose a default** if there is none.
5. Choose **Webphone**.
6. To open SMS and other call links in the Webphone too, repeat for **CALLTO**, **SIP** and **SMS**.

## Check it works

Click a phone number on a web page or in an email. The Webphone should open with the number filled in, ready to call.

Other calling apps can take over this setting when you install them. If another app opens instead, repeat the steps and pick **Webphone** again.

To stop using the Webphone for phone links, turn off **Set as a default system app for calls and SMS** and choose another app for **TEL** in Windows settings.
