Vendor

We have been working with innovative communication solutions since 1998 and have constantly expanded our specialist knowledge. Driven by consistently recurring manufacturer training courses, we have focused on selected manufacturers.

Since 2007, we have operated a hosted PBX under the name Kapsch-Businesscom GmbH, which was expanded a few years later into an XaaS cloud solution under the name of K-Businesscom GmbH. Since then, we have been operating as a value-added distributor on the market with our solutions.

Due to the merger of K-Businesscom GmbH and CANCOM GmbH in 2024, a change in the area of voice distribution was also indispensable in order to counteract a consolidation of reseller and distribution business.

Since July 2024, we have been operating our solutions and distribution under the name of ITM GmbH, headquartered in Vienna.

ITM GmbH has been established as a supplier and system integrator in the field of voice and data communication since 1987. The consulting, analysis, planning, realization and support extends over numerous customers. Distribution of the existing voice products takes place via the contacts in Neuss.

- About us

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.
The integrated Call Flow Designer allows the user to graphically design call flows. Individual flows can be created and each step can be annotated. The complex nesting and integration of announcements, DTMF functions, agents, call forwarding or timers are available in a simplified way as well as the integration of a voicemail box. However, a reference to further flows is possible.

Roadmap

The following functions will be implemented in the next versions:

extended dashboard
location management (node)
call forwarding incl. conditions
SIP trunks
template management

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.
