Windows App Installation
How to install the pascom app on Windows and on the terminal server
The Windows installation process does not require any admin privileges and be performed directly in the home-directory of the currently logged in user:
Windows Silent Installation
A silent installation is an installation method for software where no user interaction is required and no graphical user interface is displayed. With a silent installation, all necessary installation parameters are set in advance and the installation runs in the background without the user having to confirm or select anything. You can customise the target of the installation package via the properties or start the installation package via the command line.
pascom-installer.exe /S
A shortcut for the pascom app is also automatically created on the desktop.
Setting the autostart behaviour
To simultaneously adjust the autostart behaviour of the pascom app during installation, you can use the following command line parameter.
AUTOSTART="yes"
Silent Uninstallation
Proceed in the same way as for the installation. You will find the uninstaller in the app directory of the pascom app.
uninst.exe /S
Windows QoS Settings (Optional)
In order to achieve the maximum voice quality, the pascom App marks all voice data accordingly with QoS flags.
With the exception of Windows, this happens automatically on all other platforms.
The following group policies “Policy-based QoS” are required under Windows to mark the packages accordingly.
The group policies are created under the following path:
Local Computer Policy > Computer Configuration
> Windows Settings > Policy-based QoS
| Policy 1 | Policy 2 | Policy 3 | |
|---|---|---|---|
| Policy Name | pascomSIP | pascomRTP | pascom WebSocket |
| Application Name | pascom Client.exe | pascom Client.exe | pascom Client.exe |
| Protocoll | TCP and UDP | UDP | TCP |
| Source Port | * | * | * |
| Destination Port | 5060:5062 | 30000:35000 | 443 |
| Source-IP | * | * | * |
| Destination-IP | * | * | * |
| DSCP Value | 24 | 46 | 24 |
| Throttle Rate | -1 | -1 | -1 |
Terminalserver Installation
(Optional) On the Microsoft Terminal Server it is possible to install the pascom desktop App directly in the programmes directory instead of the corresponding user’s home directory.
The disadvantage of this type of installation is that you will need to manually perform all pascom desktop App updates, as the updates require admin rights. The advantage of terminal server installations is that you can save upto ca. 100MB storage space per user.
Example
pascomClient-setup.exe /D=C:\Program Files\pascom Client
The automatic updates of the pascom App are only deactivated if the pascom App has no write permissions. This is the default behaviour if you use the example path. Otherwise, it may happen that auto-updates are activated and you have to deactivate them again via flags or environment variables.
Use RDP Split Mode on Terminal Server
RDP mode is activated by default when the pascom APP detects a terminal session. Therefore, no complicated configuration is required on a server environment. However, it can be deactivated with environment variables.
Using the command line parameter --rdp or by setting the environment variable PC_RDP it is now possible to disable softphone and video support for the App on the Terminal Server. This allows the App on the Terminal Server to use the softphone of another App instance for telephony.
This allows e.g. to start one App instance within an RDP session and another one on the host computer. The instance running within the RDP session has the --rdp flag set, the outer one does not. Thus, a headset connected to the PC can be used for telephony.
What does this do?
- Better audio quality, as the audio does not have to be transferred to the RDP session
- Headset control (e.g. Accept via button on headset) works as a result.
- Integrations in software running on a terminal server (e.g. Outlook, DATEV) still works.
- Less CPU load on terminal servers, since audio and video are encoded and decoded via the App on the respective terminal device.
- Call control is fully possible via each of the Apps.
The feature works across platforms (Windows, macOS, Linux) and is not limited to RDP sessions.
Windows Installer Command Line Parameters
| Parameter | Explanations |
|---|---|
| /S | Enables an installation in to run in the background, without displaying any dialog windows. |
| /D=PATH | Enables the defining of the installation folder, i.e path. This parameter must always be the last parameter in the command line and only supports absolute file paths |
