Enterprise messaging and calling platform
Skype for Business is an enterprise-grade communication suite from Microsoft that combines messaging, voice and video calling, and collaborative document handling into a single application. Designed for workplace deployment, it can operate with cloud-based Office 365 accounts or run on a company-controlled server inside the corporate network to store calls, messages, and shared files.
Main capabilities
- Document collaboration (shared file viewing and thread-based attachments)
- Video conferencing and webinars
- Instant messaging and VoIP audio calls
Integration with Microsoft services
The app was created to work closely with Office 365, letting organizations synchronize contact lists via Microsoft Exchange and Outlook. In addition to the cloud option, many businesses use a local Skype for Business Server so that communications and stored content remain behind the corporate firewall.
User experience and interface
Conversations are organized in tabbed views so you can quickly find recent chats, incoming call requests, or shared documents. Each contact shows a presence status — for example, available, in a meeting, or presenting — so it’s easy to see who can be reached. Files exchanged in a conversation appear inline with name, size and a quick preview; interacting with a file (long-press or right-click) reveals options such as download, delete, or open.
Several visual and audio elements are borrowed from the consumer Skype client (icons, tones, presence markers), while productivity-focused controls from Microsoft’s Lync product were retained — for example, single-tap Quick Actions to message, view details, or request a call. Additional meeting and call controls live in the Skype Meeting window.
Security and media protection
Skype for Business secures signaling and media streams using industry-standard protocols, including Transport Layer Security (TLS) for signaling and Secure Real-time Transport Protocol (SRTP) for audio/video. These mechanisms protect conversations and media between clients and when interoperating with other supported messaging services.
Alternatives and options
- WhatsApp (free) — a simple option for quick messaging and voice/video calls, though it’s consumer-focused rather than enterprise-centric
- Other business-oriented platforms — enterprise IM/UC suites that emphasize centralized management, single sign-on, and compliance features
Typical business uses
Organizations deploy this solution for internal collaboration, remote meetings and webinars, presence-aware communication across teams, and secure file exchanges within the corporate network. It’s aimed at firms that need an integrated, managed communications platform tied to their Microsoft environment.
