Polycom RealPresence Trio 8800: Best Overall VoIP Conference Phone
What We Like

- Works with over 60 communications platforms
- User interface supports 17 languages
Where It Falls Behind
- Supports up to three lines only versus six offered by the Grandstream model
- May be overkill for small rooms and meetings
- Expansion microphones are pricey
Polycom RealPresence Trio 8800 Pricing
- Starts at $899.95 at Poly
- Priced from $350 to $540 on Amazon
- Additional microphones start at $181.47 for a duo pack on Amazon
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.

What We Like

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.

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.

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.

- Simple, easy-to-use device
- Large mute button for easy access
- Enhanced security with Secure Hash Algorithm 2 (SHA-2) support
Where It Falls Behind
- Only offers a monochrome, pixel-based display
- No USB connection option
- Limited 7-foot microphone pickup range
Cisco 7832 IP Pricing*
- Starts at $380 on Amazon
*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.

Grandstream GAC2500: Best Budget-friendly, Full-featured VoIP Phone for Small Businesses
What We Like
- 7-line conference bridge supports more lines than the Polycom Trio 8500
- Full-color 4.3-inch touchscreen
- Can configure six SIP accounts on one device
Where It Falls Behind
- Less intuitive to configure than other conference phones
- An older Android operating system (OS) compared to Polycom software
- Power adapters are sold separately
Grandstream GAC2500 Pricing
- Price range from $265 to $499 on third-party websites, such as IP Warehouse, VoIP Supply, and Telzio
- Pricing is not published on the website; contact sales for more information
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
