Vendor

Since 1998, we have been dedicated to innovative communication solutions and have continuously expanded our portfolio and expertise. Through consistent specialization, regular manufacturer certifications, and close collaboration with leading technology partners, we have built up a high level of expertise in select communication solutions.

As early as 2007, we established our own hosted PBX platform. This platform continued to evolve in the years that followed and was expanded into a modern XaaS cloud platform under K-Businesscom GmbH. Building on this foundation, we successfully positioned ourselves as a value-added distributor and have since supported our partners with high-performance solutions, technical expertise, and extensive project experience.

With the integration of K-Businesscom GmbH and the CANCOM Group in 2024, a strategic realignment of the voice distribution business became necessary. To ensure a clear separation between the reseller and distribution businesses and to continue offering our partners independent, focused, and specialized support, the voice distribution division was transferred to ITM GmbH in July 2024.

Building on this successful development, the next logical step was taken in June 2026: the founding of the independent ITM Distribution GmbH, headquartered in Germany. As a wholly owned subsidiary of the CANCOM Group, we now combine the flexibility, customer focus, and specialization of a value-added distributor with the stability, innovative strength, and performance of a strong corporate group.

The distribution of our voice products continues to be handled by your trusted team of experts at our Neuss location. For our partners, this means maximum continuity: familiar points of contact, short decision-making paths, and proven processes. At the same time, they benefit from the independence of a specialized distributor as well as the capabilities and extensive resources of the CANCOM Group.

Our experienced and regularly trained team supports you with comprehensive technical expertise, personalized advice, and many years of project experience. Together with our partners, we develop modern communication solutions and reliably support customer projects from the initial idea through to successful operation.

Description

The PBX-Designer for innovaphone is a PBX management application that provides an easy and graphical user interface, without the need to use the innovaphone PBX-Manager app.
The app supports both master and master/standby scenarios with full replication.

Licensing

When installing the PBX-Designer, you agree to install and use the open source product ffmpeg.
The ffmpeg application is installed when you install the application and is used for audio conversion in the application.

4 | ≤ 100
+1 | every next 100

pickup groups
boss/secretary group
call flow designer
audio files
time switch
exchange sync
call transfer

Configuration

Install the PBX-Designer via the App Store

Possibly you’ll have to go to AP Manager > App Store.
Search and install the newest K-Businesscom PBX-Designer:

Add an App instance

Select the newly installed App on the left of the screen, then click the Add button.

Fill in PBX-Designer as Name, your PBX domain as Domain and both Passwords fields.
The other fields (Webserver path, Database name & user) are automatically generated, and should not be modified. Click Save to create the instance.

Start PBX-Designer instance

The PBX-Designer app is already started automatically. Now the instance you just created, should be started as well.

First click on PBX-Designer on the left (Installed apps), then click on the instance to make the row turn blue. Now click on the Start-button.

Create the PBX-Designer App object via the PBX Manager

Close AP Manager and open PBX Manager:
Click on the “AP PBX-Designer” icon and click on the green “Create the object now” button.

The successful creation of the object is signaled.

Give users access to PBX-Designer via templates

Click on Templates inside the PBX Manager, and enable the PBX-Designer app for the correct template (typically Config Admin).

Now the PBX-Designer app is ready to be used by all users with the Config Admin template, by clicking on the 9- squares icon in the lower-right corner.

License activation

The app can now be used.
The entire content can be viewed and tested.
However, a license is required to transfer the settings to the PBX.
After the start, you will see in the dashboard, alternatively in the menu under "License") notes which information is required for a license. You can start an email from the app and fill in the missing information to trigger an order.

After ordering you will receive a file with your desired license key.
You have to activate it as follows:
In the app, go to the menu "License - License information".
Click on the "Upload license file" button.
Select the license file you have received. Only after accepting the conditions and EULA you have the possibility to upload the file.

After the successful upload you will see the activated license.

Usage

It is important to us to achieve the highest possible usability, which makes an explanation of the functions unnecessary.
Unfortunately, this does not always succeed.
Here you can find a video showing the setup of the different app functions step-by-step.
PBX-Designer HowTo (Video)

The import template is based on innovaphone's standard CSV UFT-8 format, but without group functions.
(see: https://wiki.innovaphone.com/index.php?title=Reference13r1:PBX/Config/Import)

User Import

In addition, the assignment of all licenses available via innovaphone is enabled.
An additional column is added for this purpose.
For innovaphone system licenses (without app in name) in format "lic/<innovaphone license name>".
For all other licenses available via innovaphone in the format "lic/+<innovaphone license name>".

The user then receives the assignment of the license by entering true or 1 in the field.

Here is an example:
The license "UC" is added by a column named "lic/UC".
The "App(innovaphone-chat)" license is added by a column with the name "lic/+chat".

Example File: File:PBX-Designer import-users.zip

Troubleshooting

If something goes wrong, a logfile is required to analyze the problem.
Logging must be enabled in two steps: first on the app, then on the instance.
Go to AP Manager, and select PBX-Designer on the left under Installed apps. Now directly click Diagnostics (without selecting an instance first).
Enable logging and click Save.

Now select the PBX-Designer instance (the complete row turns blue when selected), and again click the Diagnostics button.
At least select the App trace flag (depending on the problem), and Save.

Now reproduce the problem.
The logfile can be visualized via the Display link, or downloaded via the Save link.

Known issues

Requirements

The PBX Designer app requires a connection to several other apps or clients.
This table gives an overview of those required apps and the names the associated objects should have.

App	Obligated Object Name (yellow = service name)	Alternative Obligated Object Name
Devices	com.innovaphone.devices	devices-api
Files	files	files-api
Calendar	calendar
Users Admin	users-admin	usersadmin

Manual installation

If there are error messages in the application regarding access to other applications, or if the PBX object was not created automatically via the described path, some shares may be missing.
For this, please compare the settings of the PBX Designer object via the Admin-Ui with the following screenshots:

URL: https://apps.domain.com/domain.com/PBX-Designer/k-businesscom-pbx-designer

Calendar app

If the calendar app is not connected.
Please check, if the calendar apps are installed correctly.

Audio conversion on ARM devices

On devices with an ARM chipset, there may be a high CPU load due to the use of audio conversion.
This will affect the overall PBX functionality.
For files larger than 2 megabytes, we therefore recommend a workaround on devices with low CPU performance.

Convert your mp3 or wav audio file using the innovaphone Audio Converter tool (https://www.innovaphone.com/en/services/support/convert.html)
- Click on Choose File and open the file you want to convert
- Click Convert
- Once the audio file is converted, your browser will start the download of a zip containing the different codecs
Unarchive the zip containing all the different codecs
Open the Files app on your PBX
Locate and open the kdadmin folder
Drag and drop the original audio file (mp3 or wav) into the kdadmin folder
Drag and drop the contents of the unarchived zip file containing the different codecs into the kdadmin folder
Give the PBX-Designer a moment to detect the new audio files
Open the PBX-Designer app and find your new audio file on the Audio Files page under System Settings

Data synchronization

When using the PBX-Designer and the AdminUI at the same time, there may be problems in synchronizing the data. Since both apps are accessing the PBX at this moment, one of the two apps may display an out-of-date status of information.
To avoid errors, both apps should not be used at the same time.
If information is not visible in the PBX-Designer, this could be due to this. Restarting the PBX-Designer will re-read the information from the PBX.

Audio files are not displayed after update

From version >13r3 240724 sr15, the folder structure for audio files has been changed.
This means that the “pbx-designer” folder will be used instead of “kdamin” within the Files app in future.
There is nothing to note for a first-time or new installation.
However, when updating to version >13r3 240724 sr15, manual adjustments must be made once if audio files were previously used via the app.

1. If audio files have already been set up using the new version, copy the files from the new folder to the old folder.
2. Delete the new “pbx-designer” folder
3. Rename the old folder to “pbx-designer
4. If any call flows were created or edited after the update with a new audio file, open those call flows and save them. This will set the correct file in the URLs.
