Cloud PBX VoIP Phone System FAQ
What is a Cloud PBX VoIP phone system, and how is it different from a traditional PBX?
A Cloud PBX is a business phone system hosted in the cloud rather than on-site hardware. It typically uses internet calling (VoIP), so you can manage numbers, extensions and call routing through an online portal and use desk phones, mobiles or softphones.
Cloud PBX eliminates hunting lines entirely—we manage all calls in the cloud without needing physical infrastructure.
Cloud PBX still uses blocks of 10 numbers but removes the need for on-premise PBX hardware.
You can learn more about this setup in our guide on how number porting works in VoIP systems.
How much does a Cloud PBX VoIP phone system cost for a small office in Singapore?
Costs are usually monthly per user/extension, plus any local numbers and call charges. The total depends on how many users you need, whether you want call recording, IVR, call queues, and any international calling requirements.
How quickly can you get us set up and port our existing numbers?
New numbers can often be live quickly, while porting existing Singapore numbers usually takes longer because it depends on carrier checks and paperwork. Plan for anywhere from a few days to a couple of weeks, and keep your old service active until the port completes.
Will call quality be reliable in an office tower, and what internet connection do we need?
Call quality is generally excellent with a stable business-grade connection and good internal network setup. A wired connection, sufficient bandwidth per concurrent call, and basic QoS (prioritising voice traffic) help ensure clear calls during peak office hours.
Can staff take calls on their mobiles or when working from home?
Yes. Most Cloud PBX systems support mobile and desktop apps, so users can make and receive business calls on their devices, keep a consistent caller ID, and transfer calls or check voicemails from anywhere.
What do we need to prepare before installation and go-live?
Prepare a list of users and extensions, desired call flows (e.g., main line greeting, departments, after-hours rules), and any numbers to port. If you’re using desk phones, confirm power and network points, and share firewall/network details if IT needs to whitelist or prioritise VoIP traffic.
Key Questions for your new provider when choosing a new Cloud PBX VoIP Telephone System
Are You a Facilities-Based Operator (FBO) or a Services-Based Operator (SBO)?
A Facilities-Based Operator (FBO) owns and operates its own infrastructure, offering greater control over service quality and reliability.
A Services-Based Operator (SBO) relies on third-party networks, which may affect performance and long-term service stability. Knowing this distinction helps gauge the provider’s capability to meet your business needs.
For a deeper dive into the differences between traditional setups and cloud-based solutions, visit ourguide on VoIP in Singapore.
OIT functions as a systems integrator to find out what’s your business goals, and finds a suitable operator for your needs. We provide first-mile IT support from Raffles Quay for the operator that we recommend.
What Is Your Response Plan for Downtime, and How Will I Be Notified of Any Service Issues?
Downtime can disrupt operations, so understanding the provider’s approach to handling outages is crucial.
Ask about their monitoring systems, notification processes, and backup solutions.
Ensure they offer clear communication about planned maintenance and unexpected service disruptions.
OIT actively monitors providers for downtime and notifies both provider and customer of service related issues over email.
What Are Your Number Porting Out Policies and Applicable Fees?
If you decide to switch providers, knowing the process and costs involved in porting out your number is essential.
Some providers impose restrictions, delays, or fees, which could complicate the transition.
Clarify these terms in advance to avoid unexpected challenges.
If you’re unfamiliar with number porting, we’ve explained thefull number porting process here—including how to prepare and what to expect.
For OIT, the porting fees vary from provider to provider. Most providers charge no fees for number port in or port out.
Questions for yourself/existing provider while choosing a new Cloud PBX VoIP Telephone System
When Does My Current Contract End?
Contract completion is a prerequisite for porting ISDN numbers.
Overlooking this detail can cause unexpected downtime or additional fees.
Reviewing your contract’s end date ensures a smooth transition without disruptions.
Is My Timeline for VoIP Implementation Realistic?
Plan ahead and determine whether number porting is possible on time, especially if you need your VoIP system up and running before relocating or switching providers.
Porting dates are typically non-negotiable, so factor this into your timeline to avoid service gaps.
How Important Is Transparency About Pricing, Data Centre Locations, and Security Policies to Me?
Consider how much transparency impacts your decision-making.
Do you need clear pricing structures, visibility of data centre locations, and well-documented security policies such as Information Security Management Systems (ISMS) and data protection measures?
Lack of transparency can cause unexpected costs, compliance risks, and uncertainty regarding data management.
OIT’s Experience with Cloud PBX VoIP Telephone Systems
In Singapore, there are lots of companies selling VoIP phone services.
The big names—Singtel, StarHub, M1, MyRepublic—offer plans at competitive prices.
Then there are smaller providers (called SBOs) who add their own services on top of the usual voice lines, like CRM integration or custom support.
We’re not one of them.
We don’t resell VoIP lines. We’re not trying to compete in that space.
And we don’t earn anything by recommending someone to you.
Our strength is in providing managed IT support, and it covers for managing your telephone systems.
If you’re still getting familiar with how VoIP systems are evolving in Singapore, we can help you see how the landscape has shifted from on-premise PBX setups to flexible, cloud-based solutions.
So, What Do We Actually Do?
We help you figure out which VoIP provider makes the most sense for your business.
Some businesses just want a basic plan that’s cheap and works.
Others need something more—like flexible call routing, CRM tie-ins, or the ability to handle a distributed team.
Whatever your needs, we help you explore the options from the lens of our IT consulting and decide what fits best.
If you want a checklist of what to ask when you’re talking to providers, this guide might be a good starting point.
Once you choose, you sign up directly with the provider—but we stay in the picture to help you set everything up.
Why Businesses in Singapore Are Moving to Cloud PBX VoIP Telephone System
Before
Imagine your business phone system is like an old-school landline at home.
You had to plug a physical telephone into the wall to make calls. If your business needed more phones, you had to install more physical phone lines, which took time and money.
Current
Instead of using physical wires, your business phones connect to the internet.
This means:
✔ No more expensive phone lines—you only need a stable internet connection.
✔ Your business number works from anywhere—whether in the serviced office, at home, or overseas.
✔ You still get blocks of 10 numbers (like before), but calls are handled by a Cloud PBX, which means no more on-premise PBX hardware.
✔ Employees can answer calls using Fanvil VoIP phones, mobile apps, or laptops—no need to be stuck at a desk.
If your business is still using old ISDN phone lines, switching to Cloud VoIP ensures your numbers stay the same while giving you more flexibility and lower cost
