# phone.systems(TM) Click-to-Call Chrome Extension

The **phone.systems(TM) Click-to-Call** Chrome extension connects phone numbers
displayed on web pages with the phone.systems(TM) desktop app. It lets you place
calls from websites, CRM systems, and other browser-based tools without
re-entering the number in the app.

## Key features

- Automatically detect and highlight phone numbers on web pages, including
  numbers loaded after the page opens.
- Call detected numbers through the phone.systems(TM) desktop app.
- Open numbers in the app dial pad or copy them in E.164 format.
- Enter or paste numbers manually in the extension.
- Format local numbers using the selected default country.

## Before you begin

- Google Chrome is required.
- An active [phone.systems(TM) subscription](https://my.didww.com/#/phone_systems) is required.
- An installed and activated phone.systems(TM) desktop app is required. See
  [Install and Activate the phone.systems(TM) App](../configuration.html#ps3-setup-phone-systems-app).

## Install the extension

Install the extension from the Chrome Web Store.

1. Open [phone.systems Click-to-Call in the Chrome Web Store](https://chromewebstore.google.com/detail/phonesystems-click-to-cal/ifhmbpnigeffbjnknldfljppgfdfoddp).

### Step 2: Configure number detection

The extension converts supported numbers to **E.164 format**, which includes a `+` symbol and
the country code, before calling or copying them. For numbers without a
country code, it uses the default country selected in the settings.

1. Under **Default Country**, select your **Country**. To use a country not
   listed, select **Other / Custom** and enter the **Country Dial Code**.
2. Under **Page Detection**, select **Enable number detection on web pages**
   to detect phone numbers and show the phone.systems(TM) action icon next to
   them. Clear the checkbox to disable number detection.
3. Select or clear **Highlight phone numbers on pages**. This controls the
   background highlighting of detected numbers. The phone.systems(TM) action
   icon remains available when highlighting is off.
4. Under **Lithuanian Local Numbers**, enable **Enable Lithuanian local mobile
   number normalisation** to convert Lithuanian mobile numbers beginning with
   `8` to `+370` format. Clear the checkbox if this conversion is not needed.
5. Click **Save Settings**.

To restore the default extension settings, click **Reset to Defaults**, then
click **Save Settings**.

web pages, including numbers loaded after the page opens.

     [Dial Pad](../dialpad.html#ps3-application-dialpad) without placing a call.
   - **Copy** copies the number to the clipboard in E.164 format.

## Common issues

If you cannot detect a number or open a call, check the following settings.

The phone.systems(TM) app does not open

Make sure the desktop app is installed and activated. If Chrome asks for
permission to open phone.systems(TM), allow it.

A local number is formatted incorrectly

Check **Country** and **Country Dial Code** in the
[extension settings](#ps3-click-to-call-configure). You can also enter
the number with its full country code.

A number is not detected

Check that the extension is [enabled in Chrome](#ps3-click-to-call-enable-disable) and that **Enable number detection on
web pages** is selected in the [extension settings](#ps3-click-to-call-configure). Numbers in editable fields, links,
buttons,
code blocks, or unsupported formats may not be detected. Use [manual
number entry](#ps3-click-to-call-manual-number) to call the number.
