CTI mode / Softphone mode

As a default, your Softphone Pro will start in the Softphone mode. You can restart the app as a CTI client (also referred to as CTI mode).

What is the difference?

Softphone mode

The softphone mode is the basic use case of the Softphone Pro: Using the app as your telephony device with a wide range of options for making calls, monitoring the call status of your team members and managing contacts.

CTI mode

In the CTI mode, you can use the Softphone Pro as CTI Client for another telephony device, usually a desktop phone. While you use your desktop phone to make calls and monitor the call status of your colleagues, you have the Softphone Pro to manage features and setup of your desktop phone.

Depending on the mode you started the app with, some features are or aren't available. In the table below, you can see an overview of the most important differences:

Feature	Softphone mode	CTI mode
Status indicator	Yes	No
Make calls	Yes	No
Operatorpanel	Yes	No
CTI settings	No	Yes
Media device settings	All options available	Only ringtone device options available
System settings	All options available	Some options unavailable
TAPI settings	Two options, effect softphone	Three options, effect desk phone

For more information on how to configure CTI settings, go to CTI settings for desktop phones.

What is Operator Panel Mode?

The Operator Panel Mode view is an interface optimised for call handling.

A Voice Operator Panel (VOP) is a software or hardware solution designed for professional call management in companies, call centers or reception areas. It enables operators or receptionists to efficiently control, route and monitor incoming and outgoing calls.

Softphone Pro does not explicitly differentiate between use cases in terms of functionality, as most features are available across all applications.

This is because, instead of offering multiple products, an all-encompassing software solution is provided that covers both everyday telephony and specific operator requirements equally. Uniform graphical elements and functions apply to both operating modes. Thanks to consistent meanings and clearly recognisable symbols, the Operator Panel Mode can be used immediately without any training time.

The key factor is the handling: Larger overviews for better call control, usability across multiple screens (call panel, contacts) and optimal integration of various contact sources with cross-database phone number reverse lookup.

Advantages of a Voice Operator Panel Mode

1. Centralised call management

Manage multiple calls simultaneously
Easy call forwarding (blind transfer, attended transfer)
Call monitoring and control

2. Increased efficiency and speed

Drag-and-drop call routing
Quick search for contacts and extensions
Speed dial buttons and hotkeys for frequent actions

3. Improved overview and transparency

Display of call status for all extensions (busy, available, in conversation)
Integration with CRM or Helpdesk systems
Detailed call logs and statistics

4. Integration

Support for various CTI interfaces, e.g., TAPI, Outlook integration, LDAP etc.

5. Scalability

Suitable for small businesses to large-scale installations in medium-sized enterprises or corporate environments

6. Enhanced user friendliness

Intuitive user interface with graphical representation
Customisable dashboards

Typical use cases

Typical use cases include:

Businesses with high call volumes
Reception desks in hotels, hospitals or large companies
Call centers and support hotlines
Government agencies and public institutions

To use this feature, you need the TAPI driver provided in the Softphone Pro installation process. If you didn't install the TAPI driver, please repeat the installation of your Softphone Pro.

TAPI for desktop phones

If you would like to use TAPI on the workstation on which the software is installed, no special settings are required. The software finds all the settings automatically.

If you would like to use the TAPI service on a remote computer, such as a terminal server, make sure to do the following:

Enter the domain or IP address of the server or PC on which the TSP driver is set up and accessible.
2. Add the TCP port under which the TSP driver is addressed.
Example: 192.168.20.112:21077
Select a numeric TAPI line number on which data is to be exchanged.
Please note that each TAPI line can only be paired with one device.Customer-specific sender ID for TAPI
Sends a specific, fixed TAPI ID. The CLIP feature must be supported by the SIP service provider.
Please note that it is only available in CTI mode.
Select a TAPI line in the respective SIP soft client that is to communicate with the TAPI server instance.
Enter your TAPI server address (e.g. your terminal server) including the TCP port.
Select Use Server to activate the TAPI server function.

TAPI TSP

Calls that are routed through the softphone are signaled by our TSP (Telephony Service Provider) automatically to all other TAPI compliant applications (Outlook plug-in or other third-party CRM software). Third-party applications can use information that is offered by the phone to open contact windows or notice forms.

TAPI TSP requirements

Supported Systems	32 and 64 Bit
Provider name	GlobalIPTel TSP (32Bit) or GlobalIPTel TSP (64Bit)
TSP Line (Device)	GlobalIPTel Multiline 000 - 049 (standard, line count depends on license)
TSP Address	GIT address
TAPI Version	TAPI 2.0

Multiline TSP

The TAPI TSP allows the parallel assignment of TAPI lines.

As a default, no individual TAPI line is set. No further configuration is required. Softphone Pro runs in a standard mode and is immediately useable (backward compatibility).

Should an individual TAPI line be used, set the desired TAPI line under Settings -> TAPI settings.

Please note that it is also needed to set the TAPI line in third-party applications (TAPI Client).

Example: Configuring TAPI in Outlook (Windows Dialer)

1. Select a contact.

2. Right-click.

3. Select Call.
⇒ The new call windows opens.

4. Click Dialing Options.

5. Select Global IP Tel Multiline at Connect using line.

TAPI server (TSP)

Softphone Pro is available with a free TAPI server (TSP) component. It allows to open a TAPI data connection between a personal computer (workstation) and any computer which acts as a server (e.g. Windows server 2019 used as a terminal server).

On the target system (server), it is only necessary to set up the Global IP Telecommunications TSP driver (giptsp64.tsp for 64-bit Windows or giptsp32.tsp for 32-bit Windows).

TAPI server step-by-step

Download the TSP driver (32 Bit or 64 Bit).
Copy the downloaded driver to the folder c:\windows\system32.
If a TSP driver with an older file date already exists, overwrite the old TSP driver with the new one.
Please note that you might need to restart the system restart to be able to overwrite the TSP driver.
Open the Phone and Modem configuration of Windows OS. You can easily locate the program by entering "phone and modem" into the Windows search box.
Click Add….
Select Global IP Tel TSP (64Bit) in the pop-up window.
Click Add to finish the driver set-up.
Open the registry.
Define a listening port (TCP) and the number of TAPI devices (lines) that fit your needs.
[HKEY_LOCAL_MACHINE\SOFTWARE\GlobalIPTel\TAPI]
"TSPListeningPort"="21077"
"TSPNumberOfLines"="32"
The registry entries need to be created manually due to the lack of administrative rights of the Phone and Modem tool.
Select Global IP Tel TSP (64 Bit).
Click Configure to set the count of TAPI TSP line devices that you need.
The TSP makes a maximum of 255 TAPI lines available, as there are restrictions in the maximum number of TAPI line devices in the operating system.
Important: After changing the number of TAPI lines, you need to restart the server in order to make the change effective.
Security: All transferred data are encrypted. Allow the server firewall to receive data on the initial listening port (our example: 21077 TCP). Use the TAPI server environment for security aspects in a VPN environment.
Choose the TAPI line in the respective SIP softclient that shall communicate with the TAPI server instance.
Enter your TAPI server address (e.g. your terminal server) including the TCP port.
Select Use server to activate the TAPI server function.

JSON import

JSON data source links
Contacts can be imported from JSON data sources with a URL link or file link. URL data sources are URLs that can be accessed without authentication, with HTTP-AUTH or oAUTH.

Static files
Static files that are created once for the import or updated cyclically can also be used.

Once/cyclical imports
Regardless of the data source, you can import/synchronise contact data 'once' or cyclically.

Unique contact ID assignment
A unique contact ID assignment is preferable to avoid duplicates during cyclical import processes.

Importing from local data sources
To import from local data sources, please use a special form of path specification and add "file:///" before the drive specification, e.g. "file:///d:/json-csv/data.json".

JSON structure
The JSON structure is not subject to any special specifications. JSON objects can be addressed directly and customised for import. This applies to simple objects and JSON arrays.

Value assignment
The data to be imported is assigned using the simple principle of value assignment by object path:
[Value to be imported] -> [Local value]

Example of a simple JSON structure for a single "contact object":

[
{
  "id": "10201",
  "cn": "Tim1-WEB",
  "sn": "Harper1",
  "mail": "tim1@testmail.com",
  "title": "Product Manager1",
  "o": "Test Company Inc.1",
  "postalCode": "11111",
  "street": "street1",
  "jpegPhoto": "",
  "extension": "300",
  "data":
{
  "postOfficeBox": "PO127653-T3",
  "st": "NY"
},
  "phoneUseBLF":"1",
  "phoneUsePresence":"0",
  "AssignedSIPAccountID":"placetel"
}
]

Import example "First name"

Import example 'post office box'

When importing from an array, every array index is checked and imported, provided that usable data is available.

"numbers": {
  "PRIVATE": [
{
  "id": "",
  "number_e164": "4964454930560000",
  "number_disp": "4930567890"
},
{
  "id": "",
  "number_e164": "4964454930671111",
  "number_disp": "4930678900"
}
]

In some cases, you need to modify the data to be imported. Two functions can be used for this purpose, which influence a value during the data import. These functions can be combined several times in the object path specification. Functions and object specifications are logically linked with "|" (pipe).

writeIfNotEmpty("<Value>") -> only writes the value if the result is > NULL
write("<Value>") -> always writes the value, regardless of the result

Example:

writeIfNotEmpty("+")|numbers/PRIVATE/number_e164

Result:

+4964454930560000

+4964454930671111

Example:

writeIfNotEmpty("+")|numbers/PRIVATE/number_e164|write("123")

Result:

+4964454930560000123

+4964454930671111123

Special handling when importing group assignments:

You can make a group assignment of a contact by importing data into the Assignment to contact group field.

The following applies:

External group designations always take precedence over the program groups.
- The internal program group Favorite is the only group that can be used and assigned haptically alongside the externally supplied groups.
- Group names are NOT treated as case sensitive during the import. This avoids multiple groups with different spellings of a group type (Friends, friends, FrienDs).
- Imported groups are permanently stored in the application. You will need to delete groups that are no longer required in the group management. Deletion via JSON is currently not provided.

Import example groups from an array:

"groups": [
{
  "id": "14741",
  "name": "Friends",
  "desc": "Friends"
},
{
  "id": "14744",
  "name": "Partner",
  "desc": ""
}
]

If no contact groups with the names 'Friends' and 'Partner' exist, these are created. The contact currently being imported is also assigned to the 'Friends' and 'Partners' groups.

Import of image files:

Image data is always expected in JPEG image format. You need to convert JPEG files to BASE64 format for any import.
