Traditional form factor with modern functionality
Category: Cordless | Key features: Landline/IP functionality, 1.8” TFT color display; HDP sound quality; Can add five more handsets
If you need a simple cordless handset that can be used with a lineline or over the internet, this German-engineered handset is worthy of consideration. By connecting the C530IP to an internet router, it can be used for making up to three parallel calls removing the need for separate lines for multitasking. It also features a 1.8-inch TFT color display where VIP contacts can be saved and assigned custom ringtones. Just be aware that this handset is no longer compatible with Skype.

Big touchscreen makes video calling easy
Category: Wired | Key features: 7-inch, 16:9 backlit capacitive touchscreen, 1GB RAM, SE Android 4.1.1, front camera H.264 AVC video standard
Video-calling still has many practical uses in business, and this Cisco Video IP phone makes dialling into face-to-face meetings a breeze. Its touchscreen LCD display sports 1,024 x 600-pixel resolution and is compatible with a host of meeting applications including Cisco WebEX and the Cisco Jabber messaging integration platform, in addition to on-demand cloud services.

An IP Phone for SMBs
Category: Wired | Key features: POE VoIP Phone and Device, Programmable soft keys, 3-way conference calling, HD wideband audio, TR-069/SRTP/TLS advanced security protection
An affordable entry-level IP phone for SMBs, the GXP165 is capable of making excellent quality calls and features a narrow graphical LCD display that’s operated using three buttons. It offers HD wideband audio for full-duplex hands-free speakerphone operation, and it’s designed for use in larger offices thanks to an echo cancellation feature. Its large phonebook can store up to 500 contacts and 200 records in its memory, and has a built-in web configuration that can fetch the phone’s IP directly from the LCD display for IT support.
5. Yealink SIP-T46S IP Phone
A mid-range IP phone with a useful display
Category: Wired | Key features: Up to 16 SIP accounts, 4.3-Inch Color Display, dual-port gigabit ethernet, 802.3af PoE
This Yealink IP phone is great option if you’re seeking a phone with a big and useful display that’s operated with buttons rather than using your greasy fingers. It offers excellent call quality, houses a dual-port Gigabit Ethernet port around the back and can work with up to 16 SIP accounts. Just be aware that this model does not have Wi-Fi built into the handset and requires a dongle for such functionality. Not does it ship with a power supply due to having POE (power-over-ethernet) built into the unit).
6. Cisco CP-8865 IP Phone
A great option for video calling
Category: Wired | Key features: 720p HD video calling, Programmable line and feature keys, Integrated switch 10/100/1000, 720p HD video, webcam

It offers exception call clarity, and video calls stretch to 720p HD which looks clear and crisp on its small display. There’s also programme feature keys which can be customised to be used with a variety of deployment options including Cisco on-premises hosted calls, Webex Calling, and other third-party alternatives. To top off the package, this unit features USB ports for charging smartphones or Bluetooth headsets.
7. Grandstream GS-GXP2170 VoIP Phone & Device
An affordable VoIP phone that feels high-end
Category: Wired | Key features: 12 lines, 6 SIP accounts, 5 soft keys, 5-way voice conferencing, 48 on-screen customisable BLF-speed dial keys
This Grandstream unit features an elegant dark and sleek design with a large colourful display to give it a modern touch, though we found that the display suffers from a very slight amount of latency when you’re whizzing through its various menus. But for the price, you get a great package – the unit itself has a high-end feel in the hand that belies its affordable price tag. In terms of functionality, it features Dual Gigabit ports, integrated PoE and the ability to speed dialling up to 160 contacts (48 can be displayed on-screen for dialling).
8. Polycom VVX300 IP Phone
A media phone that won’t break the bank
Category: Wired | Key features: 6 lines, Polycom Zero Touch provisioning, Web-based configurator, Integrates with third-party UC applications and open APIs

9. Cisco SPA525G2 5-Line IP Phone
Built-in Wi-Fi is the main selling point here
Category: Wired | Key features: 5-line business IP phone with enhanced connectivity, 3.2-inch QVGA 320 x 240 color display, 802.11g Wi-Fi, VLAN-capable dual switched ethernet ports, Bluetooth enhanced integration, Cisco Monitor View support
Cisco calls this model a handset that’s ‘as smart as any smartphone’, which is a contentious claim (excuse the pun) and doesn’t quite ring true (and again). However, it is one of the most feature-packed on our list, featuring built-in Wi-Fi without the need for a dongle. The SPA5252G also can transfer calls to a smartphone to easily take a call out of the office. Most impressive of all is its support for Cisco MonitorView, which allows you to stream video to its 3.2-inch color display from a remote IP camera.
10. Grandstream DP720 Dect Cordless VoIP Telephone
Offers better call quality than many desk phones

It supports up to 10 SIP accounts per handset, immediately displays caller ID instead of between the first and second rings, it and can handle multiple calls in wideband voice quality.
