Video Teller Machine (VTM): How It Works, Banking Use Cases and Technology

A video teller machine (VTM) is a banking terminal that combines self-service transaction capabilities with real-time video access to a remote bank employee. To a customer, it may look similar to an ATM. The difference appears when the transaction requires human assistance. Instead of walking into a branch and speaking with a teller across a […]

Telepresence Video Conferencing: How Immersive Meeting Rooms Work

Telepresence video conferencing is designed to make people at different locations feel as if they are participating in the same physical meeting. That goal makes telepresence different from ordinary video conferencing. A conventional video meeting focuses primarily on establishing reliable audio and video communication. Telepresence goes further by coordinating: cameras; displays; microphones; speakers; participant positioning; […]

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, Architecture and Platform Options

SIP video conferencing connects standards-based video endpoints, conference rooms, telephony infrastructure, and conferencing platforms through the Session Initiation Protocol. The concept sounds simple until a vendor says its platform “supports SIP.” That statement can describe very different architectures. One system may include a SIP registrar and gateway directly inside the conferencing server. Another may connect […]

Low Bandwidth Communication: Definition, Challenges, and the Best Tools to Solve It

Low bandwidth communication refers to any voice, video, or data exchange that must function reliably over a limited, unstable, or expensive internet connection, typically below 1 to 2 Mbps. It matters because a growing share of remote workers, field teams, rural offices, and entire countries do not have access to consistent high-speed internet, yet still […]

Hosted Unified Communications: How Hosted UC Works and What to Compare

Hosted unified communications, or hosted UC, is a delivery model in which a third-party provider hosts and operates the central communication applications used by a business. These applications can include: business calling; instant messaging; presence; video meetings; voicemail; conferencing. The key distinction is not simply that the software is “in the cloud.” A more useful […]

Video Conferencing for Government: The 2026 Guide to Secure Public-Sector Meetings

Video conferencing for government is a category of communication technology built specifically for the security, compliance, and sovereignty requirements of public-sector organizations. Unlike consumer or general business tools, government-grade platforms are designed around three non-negotiable pillars: data control, verifiable encryption, and deployment flexibility, including on-premises or air-gapped operation for agencies that cannot rely on public […]

Video Conference SDK: The Complete 2026 Guide to Video Calling SDKs and APIs

A video conference SDK is a pre-built software toolkit that lets developers embed live video, audio, and chat directly into their own application, without building the underlying real-time media engine from scratch. Instead of spending months on codecs, network adaptation, and signaling infrastructure, a team can drop in an SDK and ship working video calls […]

Audio Conferencing Software: Features, Types and Best Platforms

Audio conferencing software lets multiple participants join the same live voice meeting through telephone networks, internet-based audio, or a combination of both. Unlike a normal one-to-one phone call, audio conferencing software is designed to manage a shared session with multiple participants. A useful model is: participant → access method → conference bridge → shared audio […]
