Polycom RealPresence Trio 8800: Best Overall VoIP Conference Phone

The Polycom RealPresence Trio 8800 is the best overall VoIP conference phone providing the highest acoustic clarity with a frequency response of 100 hertz (Hz) to 22 kHz, compared to the Trio 8500’s 200 Hz to 14 kHz. Handle meetings and adjust volume settings easily using its gesture-based, multi-touch-capable capacitive screen and three multicolored capacitive-touch mute indicators.

The 8800 includes Wi-Fi network connectivity, Bluetooth, and NFC (near-field communication), fit for larger meetings with eight or more people, and has a 20-foot pick-up range. However, if your space is smaller and you have fewer people in the room, consider the less expensive Konftel 55Wx or Polycom Trio 8500 models. The full-featured 8800 offers more than you need.

Polycom RealPresence Trio 8800 Features

• Call management: Access your corporate directory and transfer, forward, or put calls on hold from your VoIP conference phone. It also has a one-touch speed dial, call waiting, and a do not disturb (DND) function.
• Sound: The Polycom RealPresence Trio 8800 offers the best acoustic range of all the phones on this list. It allows listeners to hear the highs and lows of most voice conversations. It also has echo cancellation and noise reduction with intelligent processing.
• Expandable: Connect up to three other conference phones and add a camera for video conferencing and content sharing. It works with Visual+ and VisualPro, accessories that enable video and content sharing—enabling you to create inclusive, collaborative experiences for on- and off-premises staff.

Polycom Trio 8500: Best for Businesses Using Skype Services

The headline feature of the Polycom Trio 8500 is that it’s Skype for Business-certified, making it an excellent choice for businesses looking for a connection between desktop and conference phone. The Trio 8500 was designed to maximize Skype for Business, Teams, and Office 365. When used with Skype for Business, the Trio displays the familiar Skype interface and supports the features of Skype, ensuring a seamless user experience.

Poly is a conference phone designed for small to medium-sized conference rooms of about six to eight people, making it ideal for small teams needing VoIP conference phones with top-tier audio quality. However, if you’re looking for a conference phone to service a large conference room, you’re better off with the Poly Trio 8800. Its specially tuned mics capture conversations within a 20-foot range.

Polycom Trio 8500 Features

• RealPresence Resource Manager: Oversee all Poly devices and configure standard or custom setups for each. In addition, integrate your conference scheduling tools for simplified meeting management from your desktop.
• Call handling: Manage up to three lines and use the local five-way audio conferencing tool to connect with additional huddle spaces.
• Multi-format sharing: Share audio, video, and content using your Polycom Trio 8500 device. It supports Bluetooth for wideband speech and multimedia streaming.

Konftel 55Wx: Best Compact VoIP Conference Phone for Mobile Teams

The Konftel 55Wx is a mid-priced compact VoIP conference phone perfect for huddles of up to 12 people. Aside from its wireless audio feature, it can stay live for up to nine hours on rechargeable batteries. Its portable design allows users to hold meetings anytime, anywhere, and it connects to computers, mobile phones, tablets, and desktop phones. Expansion microphones enable you to conduct conference calls with up to 20 people.

It’s compatible with several VoIP providers, including Avaya, Skype for Business, Cisco, and Mitel. However, it does not have video capabilities. If this is a must for you, our top pick—the Polycom Trio 8500—is expandable, enabling you to add a camera for video conferencing and content sharing.

Konftel 55Wx Features

• Scalable: As your meetings get larger, update your software using a USB-connected, Windows-based computer for free. Add expansion microphones and conference cameras for large meeting support and easily connect your tablet, smartphone, computer, or desk phone.
• Touchscreen: Use the display to switch or combine connections, record calls to an optional memory card, and use VoIP call management tools.
• Omnisound: Konftel’s audio technology is full-duplex, which supplies clear sound in both directions. The 360-degree microphones feature automatic echo suppression and static reduction to keep background noise at a minimum.

Konftel 300Wx: Best for Its 60-hour Talk Time

The Konftel 300Wx is a wireless VoIP conference phone system that works with an elective DECT base station. Like the Konftel 55Wx, it’s a portable phone, but it beats out the 55Wx in talk time. The battery lasts up to 60 hours, 51 more hours than the Konftel 55Wx or 270 hours on standby. It’s backed by a two-year warranty and supports an optional standard definition (SD) memory card of up to 2GB.

Even with the features offered by Konftel, it only provides ticketing and help center services for customer support. If you’re looking for extensive after-sales customer support, opt for the Grandstream or Cisco phones. Both providers offer live chat, phone support, help centers, and email ticketing.

Konftel 300Wx Features

• Konftel Unite app: Add the Unite adapter to your Konftel 300Wx for ultimate portability. It transfers control of your conference phone to a mobile device, allowing one-touch conferencing from a smartphone.
• On-screen menu: Your base station has six main functions viewable on the display, and you can toggle between them using the keypad. It includes a call list, phone book, conference guide, recording, settings, and status.
• Conference groups: If you regularly meet with the same people, the Konftel 300Wx makes it easier by allowing preset categories with up to six individuals. Press one button to pick a group, see who’s in it, and make a call to everyone. Once they answer, they’re automatically connected to the conference call.

Cisco 7832 IP: Best Entry-level Conference Phone With High-quality Audio

*This is a Power over Ethernet (PoE)-enabled device. If you don’t have a PoE, you will need to purchase a separate power supply unit.

The Cisco 7832 IP phone is an excellent choice for small conference rooms and private office desktops, given its superior audio quality and 360-degree room coverage with four-microphone pickup. Even with its monochrome LCD, the 7832 still offers standard call services, such as voicemail, caller ID, call waiting, call forwarding, call transfer, and call hold.

While the 7832 suits businesses looking for a basic conference phone, the next best thing for those needing advanced features is the Grandstream GAC2500. This is the most affordable device on our list and comes with a colored 4.3-inch display and built-in Wi-Fi and Bluetooth.

Cisco 7832 IP Features

• Call management: Have at your disposal a range of call features, including access to the corporate directory, message waiting indicator, and adjustable ringtones and volume levels. It also lets users see their call history and comes with an auto-answer feature.
• Directories: One of the standout features of this phone is its ability to identify incoming messages and categorize them on the screen. This makes it fast and easy to return calls using direct dial-back capability. The corporate directory integrates with the Lightweight Directory Access Protocol (LDAP) standard directory.
• Speakerphone: The Cisco 7832 comes with a full-duplex speakerphone, allowing you to place and receive calls hands-free.

Grandstream GAC2500: Best Budget-friendly, Full-featured VoIP Phone for Small Businesses

Noting that the prices listed in our review are based on both brand websites and third-party sellers, the Grandstream GAC2500 offers the best bang for your buck with six lines, seven-way calls, and six SIP accounts. Like other VoIP conference phones, the Grandstream GAC2500 has built-in Wi-Fi and Bluetooth to connect headsets and mobile phones.

However, it’s less scalable than other equipment, as it supports daisy chains of two devices versus three with the Polycom Trio 8500, and you can’t expand the voice range with additional microphones. Likewise, the 86 dB volume is less than Konftel and Poly devices, making it harder to hear in larger spaces. If you’re looking for advanced call quality and functionality, you’re better off with our top pick, the Polycom RealPresence Trio 8800.

Grandstream GAC2500 Features

• Call scheduler: Use your desktop to schedule a VoIP phone conference call or view upcoming or previous events. You can also organize conferences via your Google Calendar, which will sync with your device.
• VoIP functions: Save up to 2,000 contacts in a downloadable phone book, create personalized ringtones, and park calls. Other VoIP capabilities include call waiting, music on hold, and call logs.
• Third-party apps: Customize your phone by downloading apps from the Google Play Store, such as Skype for Business or Google Voice.
