Switching your business phone system can feel like a risk.
Will calls drop?
Will staff struggle to adapt?
Will it disrupt customers?
These concerns are common and understandable. For most businesses, a well-planned move to IP telecom happens without disruption, numbers stay the same, teams keep working, and customers notice nothing.
This guide explains exactly how to switch your business phone system to IP telecom, step by step, with minimal disruption.
Step 1: Review Your Current Business Phone System
The first step is understanding what you have today.
This typically includes:
The number of users and phone lines
Whether you’re using ISDN or analogue lines, or if you have an on-site or hosted PBX system
Call volumes and peak calling times
Any features you rely on, such as call groups or voicemail
This step is about clarity, understanding what works today so it carries over, and what can be improved as you move forward.
Step 2: Check Your Internet Readiness for IP Telecom
IP telecom relies on your internet connection, so the focus is on keeping calls clear and consistent during the working day.
Most Irish businesses already have sufficient connectivity, but it’s worth checking:
Internet speed and stability (especially if many users are online at once)
Network setup
Whether you have a backup connection in place
In many cases, no upgrade is required.
Minor configuration is often enough to ensure consistent call quality.
Step 3: Decide What to Keep When Moving to IP Telecom
One of the biggest misconceptions is that switching means starting from scratch.
In reality, most businesses can:
Keep their existing phone numbers
Reuse compatible handsets
Maintain familiar call flows for staff and customers
This is where many businesses take the opportunity to simplify. Many organisations keep what works, remove what doesn’t, and make small improvements that immediately improve call handling.
Step 4: Getting the Switching Process Right
Most switching issues don’t come from the technology itself; they come from how the move is managed.
At IP Telecom, the focus is on making the switch simple, predictable, and disruption-free.
In practice, that means:
Minimal downtime during the switch, so calls continue as normal
Keep your existing phone numbers, with the flexibility to add or remove numbers as your business changes
Connect all locations and employees, supporting office-based, remote, and hybrid teams
Full installation and training, so staff are comfortable from day one
Flexible features that can be added as needed, without complexity
Free number porting, managed end-to-end
This approach removes uncertainty from the process and allows businesses to switch with confidence.
Step 5: Test Your New IP Phone System Before Going Live
Before going live, the system is thoroughly tested in-house to confirm call quality, routing, and overall setup. In some cases, a temporary number can be provided to allow familiarisation in advance. This approach reduces risk and ensures a smooth, predictable final switch.
Step 6: Switching Over With Minimal Disruption
With IP Telecom, number porting takes place during normal working hours and is planned in advance to minimise disruption. Any downtime is brief and controlled, with calls resuming quickly once the switch is complete. For most Irish businesses, the changeover feels straightforward — staff continue working as normal, just on a more flexible, modern platform.
Step 7: Optimising Your IP Telecom System After Migration
Once your system is live, it’s worth reviewing how it’s being used and making small adjustments as your business evolves. IP telecom is designed to be flexible, allowing you to adapt as needs change.
