Every business we talk to about switching to VoIP asks some version of the same question first: “But what happens to our number?” It’s usually the thing holding people back from making the move at all, more than price or features. The good news is it’s also the easiest part to get right; your number moves across with you, and it’s protected under Australian telecommunications law.
We see this come up a lot with healthcare clients especially, where a missed or delayed call isn’t just inconvenient; it’s a real problem. That’s part of why Pear Australia built custom VoIP communication systems for practices that can’t afford any disruption to their number. So instead of just taking our word for it, here’s what actually happens, step by step.
What Actually Happens to Your Number
Your existing landline or mobile number gets “ported,” industry language for moved, from your old provider to your new one. Once the port completes, calls to your old number ring through to your new VoIP system exactly as before. Customers dial the same digits, nothing changes on their end, and nothing needs to be reprinted, re-advertised, or explained to anyone.
The technical side happens between providers, not between you and your customers. That’s the part people don’t always realise going in: switching to VoIP is mostly a background process. Done properly, your customers will never know it happened.
How to Port a Phone Number to VoIP
Here’s roughly how it plays out for most businesses:
- Check eligibility. Most Australian landline and mobile numbers can be ported, but your new provider will confirm this against your current service details.
- Submit a porting request. You’ll provide your account number, current provider details, and a recent bill; your new provider uses this to request the transfer.
- Authorisation. Your old provider confirms the details match their records. This is also the step where mismatched details, wrong spelling, wrong address, cause delays.
- Scheduled port date. A cutover time gets locked in, usually outside business hours to minimise disruption.
- The number moves. On the scheduled date, the number is redirected to your new VoIP system.
- Testing. Calls are tested on the new system before the old service is fully switched off.
Done properly, most of that happens without staff needing to do anything beyond providing the initial details.
How Long Does VoIP Switch Downtime Actually Take?
Usually minutes, not hours, if the port is set up correctly. Number porting itself is typically scheduled for a short window, often overnight or early morning, specifically to avoid any gap where calls might not connect.
That said, VoIP switch downtime can stretch longer if there are complications, mismatched account details, an old provider dragging their feet, or a business number tied up in a contract that hasn’t been properly closed out. This is where using an experienced provider matters more than people expect; a smooth way to switch to VoIP process on paper can still go sideways if nobody’s chasing the port through to completion. It’s also worth reading up on how VoIP business phone systems actually work day to day, so you know what you’re moving to, not just what you’re moving away from.
What Actually Causes Delays During Business Number Porting
Most porting issues aren’t really about the technology; they’re administrative.
- Details that don’t match. If your business name, address, or account number on the port request doesn’t exactly match what your old provider has on file, it gets kicked back.
- Contracts still in lock-in. Some legacy contracts have early exit terms that need sorting before a port can go ahead cleanly.
- The wrong number type. Ported numbers, transferred landlines, and geographic numbers tied to a specific exchange can occasionally have restrictions, worth checking upfront rather than assuming.
- Nobody following up. A port request that just gets submitted and left alone can sit longer than it needs to. A provider who actively chases it through tends to get it done faster.
Business Number Porting Rules in Australia
Number portability isn’t just common practice; it’s a right. The ACMA’s rules on porting a phone number set out clear obligations for providers, including defined timeframes and requirements around how a port must be handled once requested. Providers can’t use your contract as a reason to block or delay a valid port. If a provider is vague about how porting works or discourages you from asking, that’s worth treating as a red flag rather than a technicality.
What to Ask Before You Book Your Switch
A few questions upfront can save a genuinely frustrating week:
- What’s the realistic timeframe for porting our specific number, not the marketing average?
- Will there be any gap in service, and if so, exactly when and how long?
- Do you handle the port directly, or does it go through a third party?
- What happens if our current provider delays or disputes the port?
- Can we test the new VoIP system before the old line is switched off?
Conclusion
Switching to VoIP doesn’t mean starting over with a new number; that part is protected, straightforward, and mostly happens in the background. The parts worth paying attention to are the administrative details, matching account information, contract terms, and choosing a provider who actually follows the port through rather than just submitting it and hoping. Get those right, and most businesses barely notice the day it happened.

Frequently Asked Questions
1. Will I lose my business phone number when switching to VoIP?
No. Your existing number gets ported across to the new VoIP system and continues working exactly as before. Customers won’t notice any difference in the number they dial.
2. How long does it take to port a number to VoIP?
Most ports are scheduled for a short window, often overnight, and complete in minutes once the cutover happens. The lead-up process, submitting details and getting authorisation, usually takes longer than the actual switch itself.
3. Is there downtime when switching to VoIP?
If the port is set up correctly, downtime is minimal to none. Most providers schedule the cutover outside business hours specifically to avoid any gap in service.
4. Can I switch to VoIP if I’m still under contract with my current provider?
It depends on your contract terms. Some providers allow porting regardless, while others have early exit conditions that need to be sorted first. Worth checking before submitting a port request.
5. What information do I need to port my number to VoIP?
Typically your current account number, business details matching your existing provider’s records, and a recent bill. Mismatched details are the most common cause of delays.
