A VoIP number is simply a telephone number that lets you make and receive calls over the internet, not traditional phone lines. It works just like a normal landline number, but instead of using wires or SIM cards, it connects through VoIP technology (Voice over Internet Protocol).
Whether you run a business or need a flexible number for remote work in Ireland, a VoIP number lets you communicate without being tied to one physical place.
If you’re considering getting one, this guide will give you clear insights to help you decide confidently.
What Exactly Is a VoIP Number?
A VoIP number is linked to a person or business, not a physical phone line. That means you can make or receive calls from your computer, smartphone, or desk phone—as long as there’s a decent internet connection.
Unlike traditional numbers that are fixed to one device or location, VoIP phone systems are cloud-based. They’re portable and easy to manage, especially for teams working from different places. You could be on your laptop in Galway and still answer calls meant for your Dublin office.

How Does a VoIP Number Work?
VoIP converts your voice calls into digital packets that travel across the internet. When someone dials your number, it rings on any device connected to your VoIP app or system.
You don’t need extra hardware unless you prefer a physical VoIP desk phone. You can use your existing numbers or get a new one with an Irish area code. The entire process runs in the background, so your callers don’t notice a difference in how they reach you, but you’ll notice a difference in flexibility and control.
Why Would You Need a VoIP Number?
It’s perfect for those who want more from a business phone system. If you’re a startup, growing company, or remote worker, VoIP gives you more power for less effort.
You can:
- Forward calls to mobile or team members
- Enable voicemail to email so you don’t miss messages
- Access calls from anywhere, anytime
- Save time with cloud-based call handling
Whether you’re running support, sales, or admin, it helps streamline everything.
Is It the Same as a Landline?
Not quite. A landline number is fixed to a cable and a specific location. A VoIP number uses internet connections and is device-independent. So yes, it behaves like a normal number, but you’re not stuck to one spot.
If you need reliable outbound calls but want to ditch the limitations of old systems, VoIP is a better fit. You can also move offices or work from home—your number moves with you.
What Features Do VoIP Numbers Offer?
VoIP numbers unlock access to advanced features without needing expensive gear. These often include:
- Call forwarding to other numbers
- Voicemail to email
- Call recording
- Interactive menus (IVR)
- Outbound call routing
- Group call handling
- Auto-attendants
These are tools many modern businesses now rely on to offer better customer support and manage call flow effectively.
Are There Different Types of VoIP Numbers?
Yes, there are several types of VoIP numbers, each with a specific purpose:
- Local Numbers – Match a specific Irish city or region (e.g., 01 for Dublin)
- Toll-Free Numbers – Let customers call you at no charge
- Virtual Numbers – Not tied to a physical line; used across devices
- International Numbers – Create a presence in another country
- Ported Numbers – Transfer your existing number into a VoIP setup
Choosing the right one depends on your communication needs and how your team or business operates.
Can I Keep My Existing Number?
Yes, most VoIP providers in Ireland support number porting. That means you can bring your current landline or mobile number into the VoIP system. You keep the number your customers already know, but get all the new benefits of a VoIP phone number.
Porting usually takes a few business days, but once done, you’ll never have to worry about it again.
How Do You Get a VoIP Number in Ireland?
It’s simple. Here’s what the process looks like:
- Choose a local VoIP number provider such as SystemNet Communication, offering the most affordable VoIP phone system for Irish businesses.
- Pick your number—local, toll-free, or port your current one
- Select a plan that matches your needs (monthly or annual)
- We will help you set up your system using a web dashboard or app
- Start making and receiving calls
You don’t need any technical skills. Most systems are plug-and-play, and good support is usually available to help you configure things quickly.
What Devices Can I Use with a VoIP Number?
You can use VoIP numbers on:
- Smartphones (via apps)
- Laptops/desktops
- VoIP-enabled desk phones
- Tablets
That means you can switch devices without switching numbers. It’s a unified experience whether you’re in the office, on the road, or working remotely.
How Much Does It Cost?
Costs vary by provider and features. But generally, VoIP services are more affordable than traditional phone systems. At SystemNet, our VoIP plans start from just @ €9.99 per user / per month.
You’ll likely pay a small monthly fee for each number or user. Some plans include unlimited calling, while others offer pay-as-you-go. Either way, the savings add up, especially for businesses handling high voice call volumes.
Is VoIP Secure?
Yes, VoIP systems are secure when set up correctly. Most providers offer features like:
- Two-factor authentication
- Call encryption
- Voicemail protection
- Admin controls
It’s also good practice to monitor call logs and block unwanted numbers. Some systems also detect unusual usage patterns and alert you before fraud can happen.
What If I Have Remote Staff?
VoIP is perfect for remote teams. Since calls happen over the internet, you can:
- Add team members wherever they are
- Route inbound and outbound calls to their phones or PCs
- Let them work with the same number from home
This is especially useful if you’ve got field agents, hybrid staff, or support teams working across Ireland.
How Is the Call Quality?
If your internet connection is stable, VoIP call quality is excellent. Many systems use high-definition audio codecs that make calls sound better than traditional landlines.
But yes, your internet matters. If you’ve got slow speeds or unreliable connectivity, it may affect your experience. Wired connections or good Wi-Fi coverage can solve most issues.
Can VoIP Help Me Save Time?
Absolutely. Features like:
- Auto-attendants
- Call routing
- Voicemail to email
- One-click transfers
…all help reduce manual work. Your phone system can do more while you spend less time managing it.
And because it’s all cloud-based, changes like adding new users or updating settings take just minutes.
