Large Participant Video Conferencing: 8 Platforms for Large Meetings

Large participant video conferencing should not be compared by one maximum-attendance number. A platform may support 1,000 people in a meeting, but that number says little about what those 1,000 people can actually do. Can everyone speak? How many people can send video? Can attendees share screens? Are most participants interactive, or are they primarily […]

9 Best Free Video Conferencing Tools in 2026

A free video conferencing tool is only useful as long as its free limits match the meeting you need to run.

A platform may let 100 people join […]

Video Conferencing for Education: Platforms, Classroom Models and Selection Guide (2026)

Is Slack Encrypted? How Slack Encryption Actually Works

Yes, Slack is encrypted. Slack encrypts customer data: in transit, while data moves between users and Slack services; at rest, while data is stored on Slack infrastructure. However, this does not mean that standard Slack messages use end-to-end encryption. That distinction matters. With end-to-end encryption, message content is encrypted on the sender’s device and can […]

Telepresence Video Conferencing: How It Works and When It Makes Sense

Telepresence video conferencing is a form of video communication designed to make remote participants feel more naturally present in the same meeting space. Unlike standard video conferencing, which mainly focuses on connecting people through reliable audio and video, telepresence coordinates the entire meeting environment: cameras, displays, microphones, speakers, participant positioning, room geometry, lighting and network […]

WebRTC Video Conference: How Browser-Based Meetings Work

A WebRTC video conference allows participants to exchange real-time audio and video through a browser or application without relying on traditional browser plugins. The user experience can be simple: open a meeting link, allow camera and microphone access, and join. Behind that interface, several different systems have to work together: media capture; signaling; session negotiation; […]

Multipoint Video Conferencing: How MCU Architecture Works

A point-to-point video call connects two endpoints. Once three or more locations join the same meeting, the system has to decide how audio and video streams are distributed, where layouts are created, and which component handles media processing. That is the problem multipoint video conferencing solves. An MCU, or Multipoint Control Unit, is one established […]

SIP Video Conferencing: How It Works, Equipment and Platforms

SIP video conferencing uses the Session Initiation Protocol to establish and manage video communication sessions between standards-based endpoints, conference rooms, telephony systems and conferencing platforms. SIP itself normally does not carry the video media. It handles call setup and session control, while audio and video are transported separately through media protocols such as RTP or […]
