CRUCIAL LEARNING PLATFORM SYSTEM REQUIREMENTS

This page covers system requirements for all three course formats—In-Person, Virtual, and On-Demand—and both platforms: the Crucial Learning Platform (CLP) and the VitalSmarts Instructional Platform (VIP).

BASIC CLP SYSTEM REQUIREMENTS

These requirements apply to all web-based modalities.

• In-Person: The instructor runs CLP from their laptop and displays the session on a shared screen or projector. Because learners are together in the same physical location, they do not join the live session through CLP. However, their individual devices must meet the requirements below to register, access or download materials, use other features such as AI Roleplay, and reset their passwords.
• Virtual: Learners join the live session from their own devices using CLP’s integrated Vonage video functionality. Each device must meet the requirements below, as well as the additional Vonage requirements.
• On-Demand: Learners complete the course independently in CLP, progressing through the content at their own pace. Each learner’s device must meet the requirements below.

Requirements

• Internet connection: 7.5 Mbps or greater, plus a supported web browser.
• PDF viewer: Adobe Acrobat Reader DC (or comparable software) to open, edit, and save PDF files downloaded from CLP.
• Web browsers: The current and previous major releases of Chrome and Microsoft Edge. Internet Explorer 11 is not supported.
• Email: The platform sends emails, such as password resets, from the cruciallearning.com domain (for example, john.doe@cruciallearning.com). Make sure this domain is not blocked by your email filters.
• Required domains:
  • Crucial Learning
    • https://api.cruciallearning.com
    • https://auth.cruciallearning.com

  • Wistia (video hosting)
    • https://fast.wistia.com

CLP VIRTUAL DELIVERY REQUIREMENTS (VONAGE)

For Virtual Instructor-Led sessions, the following requirements apply in addition to the CLP system requirements above:

• Domains: Vonage cannot provide a fixed list of server names, so wildcard access is required:
  • *.tokbox.com
  • *.opentok.com
• Optimal recommended network ports:
  • REST/HTTPS: TCP 443
  • STUN: UDP 3478
  • TURN: UDP 3478

  • TURN: UDP 3478
  • TURN: TCP 443

• Video cameras, microphones, and speakers:
  • Microphones and speakers are required for virtual delivery. Video cameras are highly recommended so learners can see other participants and interact during the class. Speakers or headphones are also needed to hear course videos and other audio content.

ON-DEMAND SYSTEM REQUIREMENTS

For self-paced courses that learners complete on their own schedule and at their own pace, the following requirements apply in addition to the Basic CLP System Requirements above:

• Domains:
  • Wistia (video hosting)
