# Dial contacts

> Dialling contacts; Phone preferences

If your IP phone solution is correctly configured, you can call a contact directly from SuperOffice CRM in one of the following ways:

* Click a telephone number in the Company screen
* Click <i class="ph ph-phone" aria-label="Phone icon" /> in a dialog.
* Right-click a person in a section tab and selecting **Call *name***.
* Dial contacts.

## Dial a contact from the Follow-up and Document dialogs

You do this using the telephone button in, for example, the **Follow-up** and **Document** dialogs:

1. Open a follow-up or document.
2. Select the required contact in the **Contact** field in the dialog.
3. Click the call button next to the contact field. A list of numbers for the selected contact is displayed.
4. Select the number you want to call. The contact is then dialled.

## Call from section tabs (to contacts, selection members, stakeholders, attendees)

1. Go to a section tab containing contacts.
2. Click a phone number in a column containing phone numbers. The contact is then dialled.

## Technical requirements

To use the telephone functions in SuperOffice you may need to install TAPI software.

### Suggested suppliers

* Standard Windows dialing software
* Panasonic TSP
* PBX Dial

## Preferences

If IP phone, Skype or FaceTime is installed, you can make phone calls from SuperOffice CRM. The **Phone-link format** preference must be set correctly, either in **Preferences** > **Default values** or in Settings and maintenance. In Settings and maintenance the phone preferences can be set for individual users, user groups or system-wide.

### Available parameters

* **IP phone**: `tel:%p` (default value)
* **Skype**: `callto:%p`
* **FaceTime**: `facetime:%p`

[Template variables][2] can also be used in the phone parameters.

### Technical note for ISVs

ISVs can use the **Phone-link format** preference to define a custom call protocol instead of the default `tel:%p`. For example, you can set the value to `domycall:%p` to forward call requests to a local listener application.

To enable this, the client machine must register a protocol handler in the Windows registry:

```sh theme={null}
Computer\HKEY_CLASSES_ROOT\domycall\shell\open\command
```

The registry entry must point to the executable that processes the incoming call request. The `%1` argument contains the phone number that SuperOffice CRM passes through the custom protocol.
