Introduction

1.3.1 About VMware Horizon
VMware Horizon is a comprehensive virtual desktop and application delivery platform that enables organizations to provide a seamless and secure user experience for accessing virtualized desktops, applications, and online services. It leverages a centralized architecture for managing and delivering virtual resources, optimizing user experiences while maintaining data security.
MiCollab Client is compatible with VMware Horizon services. MiCollab Client Softphone is supported on VMware virtualized environments. Mitel has validated the following limits and requirements when deploying MiCollab Client.
Table 1: VMware Environments

Capacity

Limit

Maximum number of MiCollab Clients per VMware Server and master image

Upto 25 users
For MiCollab Client (PC and Web) where Browser Content Redirection (BCR) is not configured.

For MiCollab Web Client with BCR configured, scaling the solution on the VMware Horizon VDI platform involves the following factors: VMware guidelines, assessing the customer's infrastructure, and the solution deployed at customer site.

Softphone support

Yes

Note:
For optimal performance with 75 clients per server, it is essential to enable BCR, currently compatible only with MiCollab for Web Client configured on VMware Horizon Client. Refer to Configuring Browser Content Redirection in VMware Horizon on page 6 for BCR configuration details. If BCR is not configured, MiCollab Client will have a maximum support capacity of 25 clients per server.

Mitel recommends deploying VMware servers to support the number of users based on the table above. Mitel validated this configuration in a virtual environment. The physical server requirements would be equivalent and/or need to exceed the recommended specifications below. Also, an additional load will be placed on the VMware Server and image if the VMware Server is presenting other applications. Please follow VMware's recommendations when deploying into a mixed environment.
Benefits of using MiCollab Client in VMware Horizon
· Provides a unified platform for managing virtual desktops, applications, and user access.

Release 10.0

MiCollab Client Integration with VMware Horizon: Deployment Guide

Software Requirements
MiCollab Client for VMware Horizon requires the following:
· VMware Horizon version 8.8 or later · For BCR, VMware Horizon 8.8 or later · vCenter 8.0 · vSphere 8.0 · Windows 10 and 11 Virtual Desktop
MiCollab for PC Client virtual appliance can be deployed in a VMware Horizon environment version 8.8 or later. It supports both Desktop mode and Web mode.
The following table represents the specifications required for configuring 25 and 75 MiCollab Client users:
Note: For 75 users, following VMware Horizon guidelines is crucial, especially in mixed environments where other applications are hosted on theVMware Horizon server. This setup adds extra load on both the server and the client. Scaling the solution on the VMware Horizon VDI platform depends on VMware Horizon guidelines, the customer's infrastructure, and the deployed solution.

Preparing the Environment

This chapter contains the following sections: · Configuring VMware Horizon Infrastructure · Configuring Browser Content Redirection in VMware Horizon
This section will guide you through the steps required to prepare your virtual desktop infrastructure for a successful deployment.

3.1 Configuring VMware Horizon Infrastructure
For configuring VMware Horizon, see the VMware Documentation.

3.2 Configuring Browser Content Redirection in VMware Horizon
Browser Content Redirection (BCR) is a feature commonly used in virtual desktop infrastructure (VDI) solutions, like VMware Horizon, to optimize the delivery of web content to virtual desktops or remote applications. BCR improves the user experience by offloading the rendering of web content from the virtual desktop or remote session host to the user's local web browser.
The benefits of using BCR includes the following:
· Performance Improvement · Enhanced Quality · Reduced Bandwidth · Optimized CPU Usage · Security · Compatibility
To configure BCR in VMware Horizon, see Configuring Browser Redirection in the VMware Documentation. (In case The VMware Horizon documentation page is discontinued, check VMware Horizon documentation under https://techdocs.broadcom.com/.

Note:
The administrator requires knowledge on Active Directory and Domain Name System for enforcing the system policies while configuring BCR.

Release 10.0

MiCollab Client Integration with VMware Horizon: Deployment Guide

Note: For now, only MiCollab for Web Client supports BCR.

Deploying MiCollab Client
1. On your local device, launch the VMware Horizon Client application. This application allows you to access virtual desktop or remote application.
If not already installed, download and install the VMware Horizon Client. For more information, see VMware Documentation. Or, you can use VMware Horizon HTML Access from the web browser using the Host FQDN (https://Host-FQDN), where Host FQDN is added in the VMware Connection Server.

2. Launch the VMware Horizon Client, click on Add Server to connect to the Host FQDN server.

Release 10.0

MiCollab Client Integration with VMware Horizon: Deployment Guide

3. Type the Host FQDN of the Connection Server and click on Connect. The VMware Horizon Client starts connecting to the server.
4. Enter the user credentials and click Login.
5. When the main screen comes up, double-click the MiCollab Client icon to open the application.

Configuring MiCollab Client Settings

Once the component parts (MiCollab Client Service, MiCollab Client, VMware Horizon, and the MiCollab Client Plugin) are installed, the following user configuration steps must be completed for MiCollab Client VMware Horizon to function properly.
Device Configuration
After you have configured MiCollab Client for VMware Horizon, you must configure the devices (headsets) that work when your client is operating in VMware Horizon mode. Once the MiCollab Client Plugin has been installed, you must configure the MiCollab Client and your virtual desktop to work properly with the endpoint device (Thin or Thick Client).
Use the Softphone Settings in the Configuration menu on the MiCollab Client to configure these devices.
Ensure that you have chosen either Bluetooth or USB audio device as your default audio device for both Playback and Recording. ONLY these options work correctly with MiCollab Client for VMware Horizon:
1. On the physical device, go to Start > Control Panel > Sound. 2. Under both the Playback and Recording tabs, ensure that the default device is the Bluetooth or USB audio
device. Click on the proper device. Click on Set Default and choose Default . Under Properties, ensure Use this device is chosen. Confirm all choices.
Headsets
MiCollab Client VMware Horizon supports several headsets for audio.
Softphone settings
Configuring the softphone settings for MiCollab Client for VMware Horizon on the MiCollab Windows Desktop Client is very similar to configuring devices for the thick client version. However, there are now additional options specifically for MiCollab Client VMware Horizon.
In the MiCollab Client Configuration menu, Softphone Settings, you can choose either Local (to your machine) or View (for MiCollab Client VMware Horizon) options for both the Microphone and the Speaker settings. If you choose local, but no devices are available on your machine, MiCollab Client switches automatically to the VMware Horizon options.
Note: When you run MiCollab for PC Client in a Windows server, access to the microphone is not allowed by default. Contact the administrator to allow MiCollab to use the microphone in the Windows microphone privacy setting.

Release 10.0

MiCollab Client Integration with VMware Horizon: Deployment Guide

Expected behavior
The MiCollab Windows Desktop Client operates in one of two modes, namely: · Local softphone (meaning on the same machine at the MiCollab Windows Desktop Client itself) · View softphone (meaning as a plug-in to VMware Horizon).
In order to switch between softphones, MiCollab Client must deregister the current softphone to bring the new active softphone online. This switch over causes a delay - no more than five to ten seconds.
The UI does not directly indicate which mode of softphone is active.

Limitations of MiCollab for PC Client in VMware environment

The limitations of accessing MiCollab for PC Client in VMware environment include the following:
· MiTeam is not available (MiTeam is auto disabled when the Client is in a VMware environment). · MiCollab Client will not auto upgrade to a newer version. · Video call is not supported. · Users will not be able to share their desktop from the Client in VMware Horizon. · Users may experience slow response during large group chats.
