VoIP & IP Desk Phones for Call Centres & Offices
VoIP and IP desk phones deliver the reliability and feature set of a physical phone, combined with the cost savings and flexibility of internet-based calling. For call centres and offices transitioning away from legacy phone systems, they are a practical and cost-effective voice endpoint.
This page lists Australian suppliers of VoIP and IP desk phones. If you are searching for VoIP platform software rather than physical hardware, see our VoIP Business Phone Systems or Cloud Contact Centre categories.
What Is a VoIP / IP Desk Phone?
A VoIP (Voice over Internet Protocol) or IP (Internet Protocol) desk phone is a physical telephone device that makes and receives calls over an internet connection rather than a traditional analogue phone line. These phones look and feel like a conventional desk phone but use your organisation's network and internet connection to carry voice calls.
They are compatible with a wide range of business phone systems and contact centre platforms, including Microsoft Teams, Cisco, Avaya, Genesys, and most major cloud-based CCaaS providers. They can be used as a standalone device or alongside softphone software on a computer.
VoIP calls can be made using software (a softphone app on your computer or mobile) or a physical IP desk phone. Many organisations use both — softphones for remote and hybrid staff, physical IP phones for agents in the call centre. Physical phones offer tactile call controls and a more stable wired network connection.
Benefits of IP Desk Phones in a Call Centre or Office
Hardwired into the network via ethernet, IP phones provide a stable and consistent connection compared to Wi-Fi based softphones — fewer dropouts, more reliable call quality.
Physical buttons for hold, mute, transfer, and volume give agents fast, tactile control during calls — faster than navigating a software interface under pressure.
Most modern IP desk phones support HD voice and include echo cancellation, delivering call clarity that surpasses traditional analogue handsets.
As a standalone device, an IP phone is less susceptible to software conflicts, updates, and compatibility issues that can affect softphone applications on computers.
IP phones can be configured with secure communication protocols. Call data stays within the controlled office environment, reducing exposure compared to mobile or personal devices.
Most IP desk phones include headset connectivity (RJ9, USB, or 3.5mm), supporting wired and wireless headset use for hands-free operation.
What to Consider When Choosing an IP Desk Phone
- Platform certification: Confirm the phone is certified for use with your contact centre or business phone platform. Many cloud platforms maintain approved hardware lists.
- Line capacity: How many simultaneous lines does the phone support? Reception and supervisor roles may need more lines than a standard agent phone.
- Display and interface: Colour touchscreen vs monochrome display vs physical button layouts — the right choice depends on how agents use the phone day to day.
- PoE support: Power over Ethernet (PoE) eliminates the need for a separate power adapter, simplifying installation for large deployments.
- Headset port type: If agents will use headsets, confirm the phone has the correct headset connection (RJ9, USB, EHS for wireless headsets).
- Local support: For large deployments, a supplier with local Australian support significantly simplifies setup, troubleshooting, and ongoing maintenance.
