As technology continues to reshape how businesses operate, one area that has seen significant transformation is communication. Traditional phone systems are no longer enough for the modern workplace. Enter VoIP—Voice over Internet Protocol—a cloud-based communication solution that allows voice calls over the internet rather than standard phone lines.
Whether you’re running a startup or managing an enterprise, VoIP for business communication offers significant benefits, including cost savings, flexibility, scalability, and improved call management. In this blog post, TechGN breaks down everything you need to know about VoIP and why it’s a game-changer for your company.
What Is VoIP?
VoIP stands for Voice over Internet Protocol. It’s a technology that allows you to make phone calls using a broadband internet connection instead of a traditional phone line.
How It Works:
- Your voice is converted into digital data.
- That data is transmitted over the Internet.
- The receiving device decodes it into audio.
VoIP calls can be made through:
- Desk phones (IP phones)
- Softphones (apps on computers)
- Mobile VoIP apps (iOS/Android)
- Web-based calling platforms
Services like Zoom Phone, RingCentral, 8×8, and Microsoft Teams Calling use VoIP technology.
Why Traditional Phone Systems Are Fading
Legacy phone systems (like PBX or analog lines) have several limitations:
- Expensive setup and maintenance
- Fixed to one location
- Hard to scale with growing teams
- Lack of integration with digital tools
In contrast, VoIP leverages your internet connection and cloud infrastructure, making it a modern, flexible communication solution for businesses of all sizes.
What Is Microsoft SharePoint?
SharePoint Online is a team-based platform for collaboration and content management. It’s more than just storage—it’s where teams create shared spaces to work together.
Key Features:
- Create team sites and project hubs
- Centralize files, calendars, and news
- Control permissions at the folder, file, or user level
- Automate workflows with Power Automate
- Integrate with Microsoft Teams, Planner, and more
SharePoint is like a digital workplace where your entire department or project team can organize, track, and collaborate on shared content.
