In today’s digital-first world, businesses need more than just phones to communicate. They need integrated, scalable, and internet-powered solutions. That’s where IP Telephony comes in. Also known as Internet Protocol Telephony, it has revolutionised how companies communicate internally and externally.
Let’s start with the basics.
IP stands for Internet Protocol, the standard set of rules that governs how data is sent and received over the internet or any other network. Every device connected to a network, from your phone to your printer, communicates using IP addresses.
Telephony, while it might look like a spelling error to some, is actually the correct technical term. It refers to the technology of transmitting voice and sound over distances. It stems from the Greek words tele (meaning far) and phone (meaning voice or sound).
So, when we say IP Telephony, we’re talking about transmitting voice (telephony) over the Internet Protocol (IP)—effectively turning your voice into data and sending it through the internet instead of the traditional telephone wires.
Unlike conventional Public Switched Telephone Network (PSTN) systems, IP Telephony is digital and software-based, meaning it uses network infrastructure to deliver voice communication just like it would for websites, emails, or video streaming.
IP Telephony is a technology that uses the internet (IP networks) to transmit voice calls, video calls, and multimedia communication. It replaces traditional telephone systems (PSTN or ISDN) with software-based platforms that run over local area networks (LAN), wide area networks (WAN), or the internet.
Rather than relying on copper wires and analogue signals, IP Telephony converts voice into digital data, sends it through the internet, and reassembles it at the other end.
This entire process happens in milliseconds, giving you a real-time voice conversation just like a normal phone call.
It’s important to understand how IP Telephony relates to other commonly used terms.
Although often used interchangeably, VoIP is actually a subset of IP Telephony.
In short, all VoIP is IP Telephony, but IP Telephony includes more than just voice.
IP Telephony bypasses traditional phone carriers. This drastically reduces local and international call costs, especially for businesses with remote teams or overseas clients.
Adding new users doesn’t require additional wiring or hardware. Most systems are managed through online dashboards.
It supports not just calls, but also video conferencing, voicemail-to-email, presence, instant messaging, and more—all on one platform.
Users can connect from anywhere with an internet connection using IP phones, mobile apps, or laptops.
IP Telephony systems integrate with CRMs, helpdesks, and productivity tools to improve workflows and customer engagement.
These devices connect directly to your router or wirelessly via Wi-Fi or DECT to offer seamless communications.
IP Telephony is rapidly becoming the standard in Singapore. Many businesses are switching from traditional PABX systems to Yeastar-powered Cloud PBX solutions or hybrid VoIP models offered by local providers like Upon SG.
