What Is a VoIP Phone System?

VoIP stands for Voice over Internet Protocol. It is the technology used to carry phone calls over an internet or IP network instead of a traditional copper phone line.

VoIP gives your business more flexibility in how calls are made, received and managed. Staff can use an IP desk phone in the office, a softphone on their computer or a mobile app while working remotely, all while presenting the same business number.

VoIP does not refer to only one type of phone system. It can be delivered through a fully hosted cloud phone system, Microsoft Teams Calling or an on-premises IP PBX.

Is VoIP the Same as a Cloud Phone System?

Not exactly. VoIP describes how calls are carried. A cloud phone system describes where the PBX and call management platform are hosted.

Cloud phone system

One type of VoIP solution, with the system hosted and managed off site by a provider. There is no main phone system to maintain at your premises.

On-premises IP PBX

Also uses VoIP, but the main phone system remains at your business, with IP phones and SIP connectivity carrying the calls.

This means the right question is not simply “VoIP or cloud?” It is which type of VoIP setup best suits your team, locations, existing equipment and business requirements.

Choose How Your VoIP System Is Delivered

Cloud-Hosted VoIP

A fully hosted cloud phone system keeps the PBX, call routing and management platform off site. There is no main phone system for your business to maintain in the office, users connect through compatible desk phones, desktop softphones and mobile apps.

Well suited to businesses wanting straightforward management, remote access, predictable monthly costs and easy scalability.

Microsoft Teams Calling

Microsoft Teams Calling allows staff to make and receive external business calls through the familiar Teams interface on their computers, mobile devices and compatible desk phones, while continuing to use their existing business numbers.

A practical option for organisations already using Microsoft 365 and wanting to bring calling and collaboration into one platform.

On-Premises IP PBX

An on-premises IP PBX keeps the main phone system at your business while using IP phones and SIP connectivity. It may suit organisations that want greater onsite control, have specific integration requirements or already own compatible PBX infrastructure.

We can help determine whether retaining an onsite system or moving to a hosted platform provides the better long-term result.

One Business Number Across All Your Devices

A modern VoIP phone system is not limited to a telephone sitting on a desk. Your business numbers and extensions can be used across different devices, allowing staff to remain reachable in the office, at home or while travelling.

IP Desk Phones

Business-grade IP phones provide a familiar office calling experience with HD audio, programmable buttons, call transfer, hold and other everyday features.

Desktop Softphones

A softphone allows staff to make and receive business calls directly from a laptop or desktop computer. Pair it with a suitable headset for a practical, space-saving workstation.

Mobile Apps

A VoIP mobile app lets staff make and receive calls using their business identity rather than sharing a personal mobile number.

Conference Phones and Headsets

Professional headsets and conference devices can improve audio quality, comfort and collaboration for receptionists, call-intensive teams and meeting spaces.

Databox Solutions supplies compatible devices from leading business communications brands, including Yealink, Jabra, Poly and EPOS.

Business VoIP Features That Improve Call Handling

The features available will depend on the platform and configuration selected for your business. Common business VoIP features include:

Auto attendant and menu options Call queues and hunt groups Call transfer, park, hold and pickup Business-hours and after-hours routing Voicemail to email Call recording Mobile and desktop softphones Direct extension dialling Music and messages on hold Call reporting and analytics CRM and business application integration Microsoft Teams integration Multi-site extension dialling 1300 and 1800 number routing

We configure the system around how your business actually handles calls, rather than giving every customer the same standard setup.

Keep Your Existing Business Phone Numbers

Moving to VoIP does not usually mean giving up the numbers your customers already know.

Databox Solutions can arrange the porting of eligible local, mobile, 1300 and 1800 business numbers to the new service.

We plan the number porting, system configuration and changeover process together to reduce disruption and make the transition as straightforward as possible.

VoIP Call Quality Starts with the Network

VoIP does not require excessive bandwidth, but it does rely on a stable and properly configured business network. For fixed desk phones, a wired network connection will generally provide more consistent performance than congested Wi-Fi.

Databox Solutions can assess your internet connection and local network as part of the phone system design. Where required, we can also configure Quality of Service rules to prioritise voice traffic over less time-sensitive network activity.

  • Internet connection reliability
  • Available upload and download capacity
  • Network congestion
  • Wi-Fi coverage and interference
  • Router and firewall configuration
  • Voice traffic prioritisation
  • Cabling and network switch quality
  • The handsets and headsets being used

What Happens If the Internet Goes Down?

Because VoIP uses an IP connection, an internet or network outage can affect normal calling. The right continuity setup can reduce that risk.

The appropriate level of resilience depends on how critical phone availability is to your business. We can design internet and failover options alongside the phone system rather than treating them as separate services.

Explore Business Internet and Failover Options
  • A secondary business internet service
  • 4G or 5G network failover
  • Automatic call diversion to mobile numbers
  • Calls ringing on mobile apps using cellular data
  • Voicemail to email
  • Backup power for phones and network equipment

VoIP Phone System FAQs

What is the difference between VoIP and a cloud phone system?

VoIP is the technology that carries calls over an internet or IP network. A cloud phone system is one way of delivering VoIP, with the PBX and call management platform hosted off site. VoIP can also be used with Microsoft Teams Calling and on-premises IP PBX systems.

Which type of VoIP phone system is right for my business?

A cloud-hosted system is generally suitable for businesses wanting easy management, mobility and scalability. Microsoft Teams Calling can be a good fit for organisations already working heavily within Microsoft 365. An on-premises IP PBX may suit businesses wanting onsite control, specific integrations or continued use of existing infrastructure. We assess your requirements before recommending a platform.

Can I keep my current business phone numbers?

In most cases, eligible business numbers can be transferred to the new service through number porting. Porting timeframes and requirements depend on the number type and current carrier.

Do I need to buy new phones?

Not always. Existing IP phones may be reusable if they are compatible with the selected platform and are not locked to another provider. You can also use a desktop softphone or mobile app instead of a physical desk phone.

Can staff use the business number from home?

Yes. Depending on the selected platform, staff can use a compatible desk phone, desktop softphone or mobile app from outside the office while making and receiving calls through the business phone system.

Will VoIP work during an internet outage?

Normal VoIP calling requires a working IP connection. Business continuity options such as secondary internet, mobile failover and automatic call diversion can help keep calls available during an outage.

Is VoIP call quality reliable?

VoIP can provide clear, consistent business calling when it is supported by a reliable internet connection, suitable network equipment and correct configuration. A network assessment is particularly important for larger teams, busy offices and businesses running voice alongside other high-bandwidth applications.

Is a VoIP phone system secure?

VoIP security depends on the platform, provider and network configuration. A professional deployment should include secure account administration, appropriate encryption, firewall protection, strong passwords, restricted access and monitoring for unusual calling activity.

Can VoIP integrate with Microsoft Teams or CRM software?

Many VoIP platforms support Microsoft Teams, CRM and helpdesk integrations. Compatibility and available features vary between systems, so integrations should be confirmed during the design stage.

Can VoIP support multiple offices?

Yes. VoIP can connect users across different offices and remote locations under one business phone system. Staff can use extension dialling, shared reception, centralised call routing and common business numbers across multiple locations.

How much does a business VoIP phone system cost?

Pricing depends on the number of users, required devices, selected platform, call features, integrations, internet services and support requirements. Databox Solutions provides a tailored quote based on the setup your business actually needs.
