Business phone systems in Singapore, set up and supported properly
Your phone system is still how a lot of business gets done, and when it is clunky, dropping calls or tying you to expensive old phone lines, it quietly costs you every day. A modern IP PBX and VoIP setup fixes that: clearer calls, far lower call costs, the flexibility for staff to work from anywhere, and features that used to be the preserve of big companies. CARE designs, installs and supports business phone systems for Singapore companies, on-premise, in the cloud, or a hybrid of both, matched to how your business actually works. We have been doing this for SMEs since 2007.
We are not tied to one brand. We work across the leading platforms, including 3CX, Yeastar, Grandstream, Cisco and Microsoft Teams Phone, so instead of pushing whatever we happen to sell, we recommend the system that genuinely fits your size, your budget and the way your team works.
The phone solutions we provide
- On-premise IP PBX. A phone system that lives at your office, giving you full control of your telephony on your own hardware, ideal where you want everything in-house.
- Cloud and hosted PBX. Your phone system hosted in the cloud, with no on-site box to maintain, easy to scale and perfect for remote and hybrid teams.
- Hybrid PBX. A mix of on-premise and cloud, so you keep what works and add the flexibility of cloud where it helps.
- SIP trunking. Replace expensive traditional phone lines with internet-based voice lines, usually cutting call and line costs significantly while keeping your existing numbers.
- IP phones and handsets. Supply and setup of business-grade desk phones, conference units and headsets, configured and ready to use.
- Microsoft Teams Phone. Turn Microsoft 365 and Teams into your phone system, so calling lives alongside your chat, meetings and files in one place.
Features your business gets
A modern IP PBX brings the call-handling features that make a business look and run more professionally, including:
- Auto-attendant and IVR menus to route callers to the right place
- Call recording, call queues and ring groups
- Call transfer, conferencing and music on hold
- Voicemail, including voicemail to email
- Time-based routing, so calls are handled differently in and out of hours
- Follow-me and mobile apps, so staff take office calls anywhere
- Remote and branch extensions across multiple locations
Why move to IP PBX and VoIP
- Lower call costs. VoIP calls, especially international and inter-office, are far cheaper than traditional lines, and SIP trunking cuts line rental too.
- Work from anywhere. Because the system is IP-based, staff can make and take office calls from a laptop or mobile, at home, on the road or in another branch.
- Easy to scale. Adding a user is usually just another extension, not an engineer rewiring your office.
- Professional call handling. Auto-attendant, queues and routing make a small business sound polished and make sure calls reach the right person.
How IP PBX and VoIP work
In short, an IP PBX is the phone system, and VoIP is the technology that carries the calls over the internet instead of traditional copper lines. The IP PBX sits at the centre, connecting your extensions to each other and out to the public phone network through SIP trunks or a VoIP gateway.

VoIP itself converts your voice into digital data, sends it as packets over the internet, and converts it back to sound at the other end, all in real time, which is what makes the low call costs and location flexibility possible.

Why CARE for your phone system
- Vendor-neutral advice. We work across 3CX, Yeastar, Grandstream, Cisco and Microsoft Teams Phone, and recommend what fits you, not what suits us.
- Designed, installed and supported by us. One team plans your system, sets it up and keeps it running, rather than leaving you to deal with a vendor when something breaks.
- A Cisco Registered Partner and Microsoft Solutions Partner. Real credentials behind the networks and systems your phones depend on.
- Part of your whole IT. Your phone system tied into your network, security and managed IT, so voice and data work together properly.
- Experience since 2007. Many SME phone systems implemented across Singapore, so yours is set up by people who have done it many times.

Frequently asked questions
What is the difference between IP PBX and VoIP?
IP PBX is the phone system itself, the exchange that connects your extensions and routes calls. VoIP is the underlying technology that carries the calls over the internet rather than traditional phone lines. In practice they work together: an IP PBX uses VoIP to make and receive calls.
Should we go for an on-premise, cloud or hybrid phone system?
It depends on your business. On-premise gives you full in-house control; cloud or hosted PBX removes the on-site hardware and suits remote and multi-site teams; hybrid mixes both. We will look at how you work and recommend the right fit rather than pushing one option.
Which phone platform do you use?
We are vendor-neutral and work across the leading systems, including 3CX, Yeastar, Grandstream, Cisco and Microsoft Teams Phone. We recommend the platform that best fits your needs and budget instead of forcing a single brand on you.
Can you turn Microsoft Teams into our phone system?
Yes. With Microsoft Teams Phone, we can set up calling directly inside Teams, so your calls, chat, meetings and files all live in one place. It is a strong fit for businesses already on Microsoft 365.
What is SIP trunking, and will it save us money?
SIP trunking replaces traditional phone lines with internet-based voice lines. It usually cuts both call charges and line rental significantly, while letting you keep your existing phone numbers. For many businesses it is one of the quickest ways to reduce telephony costs.
Can staff use the phone system when working from home?
Yes. Because the system is IP-based, your team can make and receive office calls from a laptop or mobile app wherever they are, with the same extensions and features as in the office.
Can you keep our existing phone numbers?
In most cases, yes. We can port your existing numbers across to the new system so you keep the numbers your customers already know.
