UNDERSTANDING THE BASICS
The Communication Evolution: From PSTN to UC
The business communication landscape has transformed dramatically over the past two decades. With the 2027 PSTN switch-off approaching, understanding your options isn't just academic—it's essential for business continuity.
At Vehda, we guide Sussex businesses through this transition daily. This comprehensive guide clarifies the differences between VoIP and Unified Communications, helping you make an informed decision for your organization's future.
📞 What is VoIP (Voice over Internet Protocol)?
VoIP (Voice over Internet Protocol) is a technology that enables voice calls using the internet instead of traditional telephone lines. Instead of analog signals traveling through copper wires, your voice is converted into digital data packets and transmitted over IP networks.
Think of it as email for your phone calls—digital, efficient, and dramatically more cost-effective than traditional landlines.
Eliminate expensive line rental fees and drastically reduce call costs, especially for long-distance and international calls. Most businesses save 40-60% on their phone bills.
Make and receive calls from anywhere with internet access—office, home, or on the move. Your phone number follows you, not your desk.
Add or remove users instantly without engineer callouts or physical infrastructure changes. Perfect for growing businesses or seasonal fluctuations.
Core VoIP Capabilities:
🌐 What is Unified Communications (UC)?
Unified Communications (UC) is a comprehensive platform that integrates multiple communication and collaboration tools into a single, cohesive ecosystem. It combines voice, video, messaging, presence, file sharing, and screen sharing into one unified experience.
UC doesn't just replace your phone system—it transforms how your entire organization communicates and collaborates, breaking down silos between different communication channels.
