You can use the following Powershell Script (run with administrator permissions) to automatically check required Windows Features for RTC

Import-Module ServerManager

foreach ($f in $Features) {
    Get-WindowsFeature $f 
}

SQL Requirements

RTC Launcher will also require a running SQL server, as described in our Database Preparation. We usually recommend to run this on a separate machine 

Supported Platforms for the Database are:

• Microsoft SQL Server 2012
• Microsoft SQL Server 2014
• Microsoft SQL Server 2016
• Microsoft SQL Server 2017

Web-Admin Portal Requirements 

The RTC Launcher Admin Portal is compatible with the following browsers:

• Internet Explorer 11*
• Edge
• Mozilla Firefox (choose latest version)
• Chrome (choose latest version)
• Safari (Mac OS)

_{* With earlier Internet Explorer, users may face a problem with data updating (when data does not get pushed automatically than manually reload of the page is needed). It is recommended to update the Internet Explorer browser to versions 11.}

Certificates for access via secure https should not be self-signed. please contact authorized third-party companies to get them.

O365 / Azure Users

The Web-Admin Portal is installed on your system to administrate RTC Launcher via assignment of User Roles. When an O365 account login is required, make sure you have an Azure AD application ready with the following configuration:

• Select the Azure Active Directory and then App registrations
• Click on New registration
• Under authentication add a new platform web
  • 
  • with your redirect URI followed by /signin e.g.  https://rtclauncheradmin.dev.luware.com/signin
• Enable access tokens and id tokens under implicit grant
• Under API permissions add the Microsoft.Graph delegated permission for
  • User.Read
  • profile
  • openid
• Copy the application (Client) ID and the Tenant ID for later use ( See System Settings Configuration as a System Administrator)

RTC Installation

RTC Launcher relies on a running Skype for Business Server. There are several options how to use the RTC Launcher:

• Only chat
• Audio/Video calls and chat (optional)

Active / Passive Installation types

To make RTC Launcher high available it's possible to run several instances of RTC Launcher components. Different instances should be installed on different servers with the same settings.
In this case it will work in the following way:

• RTC Launcher Client Installation – several components can be available at the same time (active/active)
• RTC Launcher Admin Installation – should be configured in active/passive scenario so only one Admin application will receive all requests.
• RTC Launcher API Service Installation – should be configured in active/passive scenario so only one Service will receive all requests.

SignalR Chat solution

This implementation will use SignalR for chat and doesn't require any additional installations. SignalR allows bi-directional communication between server and client. It supports Web Sockets, and falls back to other compatible techniques for older browsers.

 More information can be found on Wikipedia and our Config Tweaks > SignalIR Section..

Pexip - Audio, Video

 Optional: Pexip is a scalable meeting platform, which works as a software-based trans-coding and interoperability engine. It connects Skype for Business with web browsers.

 Using of this option will require an additional → Installation of Pexip server.

The following Pexip features are available in browsers:

A visiting user can use a camera and microphone for Audio/Video conversation. Pexip supports this for the following browsers:

Surfly - Co-Browsing

 Optional: Surfly enables Co-Browsing functionality for your RTC Launcher users, so they can see the customer's browser content and assist with navigation. There are two options to integrate Co-Browsing into RTC Launcher:

• SaaS by Luware: Surfly licences and API keys are automatically generated. You won't need to take further action.
• Self hosted (on-prem): If you want to host RTC Launcher yourself you need to licence Surfly to retrieve API keys for each tenant. The keys are entered in the System Settings and the feature must be enabled in User Settings (Co-Browsing Tab) for each tenant. One "Agent" user is defined to access Surfly features.
   Each additional "Agent" (per Tenant) will require further Surfly licences with corresponding running cost.

Mobile Client

RTC Launcher can also be run on mobile devices (currently only supporting iOS).

• Currently supported modalities are: Chat, Audio and Video.
• Escalation is not supported
• Desktop presenting is possible.

Supported Mobile Browsers:

• Latest version of Chrome for Android 7+ version;
• Latest version of Samsung Internet for Android 7+ version;
• Latest version of Safari for iOS 11+ version.
