Polycom VVX 601: Best Overall VoIP Phone With 16 Lines
What We Like
- Easy-to-navigate touchscreen
- Has two universal serial bus (USB) ports, while most only have one
- Digital picture frame mode
Where It Falls Behind
- Costs more than other desk phones
- Conferencing limited to three people
- Doesn’t have a 3.5mm jack
Polycom VVX 601 Pricing
- $337.99 per phone through Poly.com
- Starts at $397.95 per phone through Amazon
The Polycom VVX 601 is the overall best VoIP phone for small business—connecting up to 16 lines and offering an advanced touchscreen display. Navigation is intuitive, and the device comes with four soft keys, making features like call transfer and call park easy to find. This is why the Polycom VVX 601 is our top pick for the best device for multi-line phone systems. The phone has a 4.3-inch touchscreen, a hard numeric keypad, and integrated Bluetooth.
While the Polycom VVX 601 works with Google Voice, RingCentral, Nextiva, and 8×8, it lacks a built-in video camera. The Polycom VVX Camera installs in seconds and lets users join video conferences directly from their desks. However, if you need a built-in camera, choose the Grandstream GXV3275, which accommodates up to 12 phone lines.

Grandstream GXV3275: Best for Its Video Conferencing Capabilities
What We Like
- Six SIP accounts
- Supports three-way video conferencing
- Has a built-in web browser
Where It Falls Behind
- Supports fewer phone lines than other desk phones
- Internal memory is only 1GB
- Hold music requires an MP3 upload
Grandstream GXV3275 Pricing
- Starts at $190 per phone through Amazon
The Grandstream GXV3275 is the best option for video conferencing, thanks to its sizable 7-inch touchscreen and tiltable camera. Easily host and record three-way video calls and use the privacy shutter to block the camera when it’s not in use. It has a tablet-like console with three dedicated Android keys (Home, Menu, and Back), allowing you to perform essential VoIP functions like call forwarding and call park or pickup.
This desk phone suits a variety of uses because it has integrated Bluetooth and Wi-Fi for connecting external devices. However, the Grandstream GXV3275’s Music on Hold feature requires an MP3 upload. If you want an easier way to upload music, opt for the Polycom VVX 601, which gives users two ways to add a file. They can select a file from their PC or desktop or enter a uniform resource locator (URL) link.
Grandstream GXV3275 Features
GXV3275 features full-screen video calling (Source: YouTube)

- Works with many different VoIP providers, including Vonage
- Supports VoIP call recording and voicemail functions
- Integrated Bluetooth
Where It Falls Behind
- No video capabilities
- Doesn’t have a touchscreen
- Lacks a 3.5mm jack
Grandstream GXP2170 Pricing
- Starts at $97.98 per phone through Amazon
The Grandstream GXP2170 is the best-in-class business VoIP desk phone for agents handling high call volume, with its integrated Bluetooth, seamless mobile phone, and headset sync. It features six SIP accounts allowing users to receive calls on multiple lines throughout the day, making it one of the best call center phones. The GXP2170’s full-color LCD screen and the gigabit ports ensure a reliable high-speed connection.
However, the Grandstream GXP2170 doesn’t have a 3.5mm jack or a built-in camera like the Grandstream GXV3275. Also, some staff may prefer a desk phone that feels more like a tablet or smartphone. In this case, consider a touchscreen model like the Grandstream GXV3275 or Polycom VVX 601.
Grandstream GXP2170 Features
Add multiple calls to a conference call (Source: YouTube)

- Customers report it only has average sound quality
Ooma DP1-T Pricing
- $129.98 per phone through Ooma with a risk-free 30-day return
- Starts at $85 per phone through Amazon
The Ooma DP1-T is ideal for existing Ooma users looking for compatible VoIP phone devices. The DP1-T pairs wirelessly with the Ooma Office base station (sold separately), allowing you to make and receive calls without fiddling with an Ethernet cable. Its DECT (digital enhanced cordless telecommunications) technology works within 150 feet of the base unit.
Its rechargeable battery has a 36-hour standby time and seven-hour talk time, allowing for portability between your office and the conference rooms without needing an outlet. However, it has a smaller LCD than Grandstream and Polycom phones. It’s also not a good fit if you need to answer or monitor more than two phone lines. If your business needs a full-screen display with advanced call management features, the Grandstream GXV3275 is a better choice.
Ooma DP1-T Features

- Configuration is unique compared to others
Grandstream DP720 Pricing
- Starts at $50 per phone on Amazon
The Grandstream DP720 is an affordable cordless phone that uses DECT wireless standard, maximizing mobility and call efficiency for greater productivity. This is an excellent option for professionals constantly on the phone, such as salespeople, stock brokers, liaisons, and administrative staff. It has a 300-meter range outdoors and a 50-meter range indoors from the base station, allowing unimpeded mobility.
The Grandstream DP720 is the most cost-efficient device on this list, with a starting price of $50 on Amazon. At this price, it features two soft keys and four dedicated function keys to answer, park, or transfer calls. The DP720 supports three-way audio conferencing, has provisions for a 3.5mm headset jack, and comes with full HD audio on both the speakerphone and handset.
Unfortunately, the price doesn’t include the required Grandstream DP750 base console, and the 1.8-inch color LCD is smaller than other devices on this list. This device supports up to 10 SIP connections, but if you need more, Polycom VVX 601 supports up to 16 lines. Our top pick has a 4.3-inch touchscreen and integrates with a computer softphone app.

What We Like
- Dedicated fixed keys
- Voice message waiting indicator
- Supports the Cisco EnergyWise technology
Where It Falls Behind
- Only offers a grayscale display
- Handset is reportedly uncomfortable to use
- Navigation of features has a learning curve
Cisco 7841 Pricing
- Starts at $209.02 per phone on Amazon
The Cisco 7841 is the most energy-efficient VoIP phone option in this list. All phones in the 7800 Series are eco-friendly and Energy Star-certified. Energy Star-certified devices use less energy to perform and meet energy efficiency standards. The 7841 model supports Cisco EnergyWise, a green computing technology designed to measure and optimize power consumption.
The model has a standard power-save option on the Cisco 7841 that reduces power consumption during off-hours, saving money and maximizing energy efficiency. However, despite its high-efficiency level, it does not have a colored display, a feature available with most VoIP phones.
For larger, colored displays, the GVX3275 has a 7-inch touchscreen, and the GXP2170 has a 4.3-inch color LCD.
Cisco 7841 Features
