Operation examples
Dialling
CRM Connect offers you various outbound calling methods.
)
Note that not all applications support all of the dialling methods described below.
Focus dialling
This dialling methods displays a dial icon for a field containing a phone number.
The field must be selected first or be in "focus" for the dial icon to appear.
)
Clipboard dialling
Clipboard dialling enables quick dialling by selecting and copying telephone numbers.
A dial pop-up prompt automatically appears when the number is copied to the Windows clipboard, either by keyboard or by mouse clicks – simply click the phone icon to make the call.
)
ScreenRead dialling
ScreenRead dialling allows any telephone number visible in Windows applications, documents, email signatures or images containing phone numbers to be dialled.
– Position the mouse cursor over the number to dial and hold CTRL+SHIFT to activate the "capture" box.
The "capture" box will automatically convert anything that appears to be a telephone number into a click-to-dial button.
)
Not every image may be readable due to certain conditions, e.g. digits should be horizontal and must fit within the capture box. Additionally, not every number format will be transformed into a correct telephone numer. Please consult the table below for excamples on detectable number formats:

Web Dialling Configuration
Browser Extension
Web dialling enables you to make outbound calls directly from a web browser.
1. Select a web browser extension to install.
2. Configure dialling directly from a web page for Edge, Opera, Chrome or Firefox.
)
TAPI Driver
Enable TAPI-compatible application to assist with dialling:
– Enable TAPI driver (dial only), "CallTo" protocol handler, or TAPI request handler.
TAPI driver ( dial only): This option is more commonly used than TAPI request handler, as is the case with CRMs such as Goldmin, ACT! and other desktop-based platforms. This selection is for CRM systems that support TAPI drivers via the phone and modem options on the PC. In compatible CRM systems, such as Goldmine, the UC TAPI driver can be selected from the application to initiate an outgoing call from the CRM system via CRM Connect.
CallTo protocol handler: By enabling this option, CRM Connect automatically recognises the CallTo protocol that is formatted accordingly (e.g. CallTo:[0123456789]) to initiate acall via CRM Connect.
TAPI request handler: This is used far less frequently than the TAPI driver. This feature supports CRMs that make a request to "ialer.exe. There is no configuration within the CRM, but CRM Connect creates a registry setting in dialer.exe to use CRM Connect for outbound calls.
)
Refer to the manual of the CRM manufacturer of your TAPI-enabled application to configure dialling.
General settings
Under the Advanced tab, you will find the following:
application-specific version details
language settings for the CRM Connect menu
customer feedback option which, once selected, will enable communication of anonymous data to help improve the product
application logs that contain details about the software configuration
)
Depending on the initial setup, not all user information will be displayed.
No content available.
Presence information
Presence information is currently reflecting the line state.
Line state is the telephony state of your phone and shows whether the phone is
offline (telephony line is not connected),
idle (phone is online but you are not in a call),
ringing,
in use (you are in a call).
The 4 states are telephony states.
Here are the Presence icons visible in the apps that reflect the line state and your availability:
 | Available: The user is logged and is idle |
 | Line in use: The user is currently in a call |
 | Idle line state: The user is currently not logged into an application, however the line is idle since e.g. a user has a deskphone or a mobile app installed |
 | Do not disturb: The user does not want to be disturbed. No notifications will be displayed and all incoming calls' destination will depend on the settings in the call forwarding profile. This icon appears when Global DND is activated - see below |
 | Offline: The user is currently offline and not reachable |
Do Not Disturb
There are two Do Not Disturb options available:
Device DND: The user does not want to receive calls on the device currently being used. The calls will be automatically rejected on the device where device DND is activated.
Please note that this is only applicable for users with the mobility option.Global DND: The user does not want to be disturbed. No notifications will be displayed and all incoming calls will be automatically rejected on all devices. Global DND will be visible to all users within the organisation.
Note
When activating Global DND, the call's destination will depend on the settings in the call forwarding profile.
Presence sync makes it possible to synchronise the presence status between MS Teams and DFN VoIP Centrex bidirectionally.
DFN VoIP Centrex > MS Teams
The following shows you how DFN VoIP Centrex states are displayed with MS Teams states:
| In use |  | In a call |
MS Teams > DFN VoIP Centrex
The following will show you how MS Teams states are displayed with DFN VoIP Centrex states:
|
|
In a call
In a call, out of office
| | In use |
As these are two separate applications, the presence information must be exchanged between them when changes are made on either side, which may result in a short delay.
This means that the correct information about the user's status may differ from the corresponding display in the applications for up to 60 seconds.
For example, a call in DFN VoIP Centrex may have ended, however, the user may still be shown as being on a call in MS Teams.
In addition, presence synchronisation may cause the in use status in DFN VoIP Centrex to persist longer than the call lasts.
However, this is only visual information; the user is still available for calls.
In cases where the incorrect presence status persists for a longer period of time (for example, after a DFN VoIP Centrex application crash), it will be displayed correctly after the next call.
Presence sync is limited to a maximum number of 650 extensions.

Managing advanced configurations
In this section, you will find a description of advanced Desktop App configuration options. These options offer the capability to manage update, minimise and autostart behavior.
The settings.json is a configuration file, mostly used in, but not limited to, automated roll-outs. It is located next to the Desktop App executable in the installation folder, usually located in c:\Program Files\DFN VoIP-Centrex\win-unpacked\ (Windows) or ~/Applications/DFN VoIP-Centrex.app/Contents/MacOS (MacOS).
Important
Encoding
Please note that the settings.json needs to be encoded in UTF-8.
Tip
Please note that all options are applied on the app start. If the options are changed, it is necessary to restart the app.
Configuration options
Example of settings.json:
{
"handle-updates": "IGNORE",
"access-to-traybar": false,
"autostart": true,
"microsoft-entra-fido2": false
}
handle-updates
Type: string (values: INFORM, IGNORE)
Default: INFORM
Description:
By default, the Desktop App regularly checks for new versions and prompts the user to install updates. This behavior can be undesired in an environment where software updates are centrally managed by an admin.
With handle-updates set to IGNORE, the update prompt will not be shown to the user.
access-to-traybar
Type: boolean
Default: true
Description:
By default, the Desktop App will minimise into the system tray on Windows. In some environments, for example, a Citrix environment, the system tray is not available. Setting access-to-traybar to false will cause the Desktop App to minimise to the task bar instead, making sure it is still available to the user without the system tray.
autostart
Please note that this feature is only available starting with Desktop App v2.0.0.
Type: boolean
Default: false
Description:
By default, the Desktop App needs to be started after each machine restart, for the user to be available for calls. This option can be used to automatically start the Desktop App on machine start.
Tip
The autostart feature of the Desktop App can be managed using the system settings.
If the feature is not working as intended, please also check your system settings to confirm the Desktop App is allowed by the system to automatically start.
Windows: Settings > Apps > Startup
MacOS: System settings > General > Login Items
microsoft-entra-fido2
Please note that this feature is only available starting with Desktop App v2.1.0.
Type: boolean
Default: false
Description:
Enables support for FIDO2 security key login with Microsoft Entra ID (formerly Azure Active Directory).
Microsoft Entra may block security key authentication in some environments unless specific compatibility requirements are met. Activating this option ensures that the Desktop App is recognized as compatible for FIDO2 authentication during login.
Please note that this requires restart of the application when changed while the Desktop App is running.
Automatic creation via PowerShell
The following PowerShell script can be used to automatically create the JSON file:
create-local-settings.ps1
# Define your data as a PowerShell object (hashtable)
$data = @{
"handle-updates" = "IGNORE"
"access-to-traybar" = $false
"autostart" = $true
"microsoft-entra-fido2" = $false
}
# Convert the PowerShell object to JSON
$json = $data | ConvertTo-Json -Depth 4
# Specify the path for the JSON file
$jsonFilePath = "C:\Program Files\DFN VoIP-Centrex\win-unpacked\settings.json"
# Write the JSON string to the file without BOM
[System.IO.File]::WriteAllLines($jsonFilePath, $json)
