Polycom VVX 601: Best Overall VoIP Phone With 16 Lines

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.

Polycom VVX 601 Features

• Call handling: Enhance the way your phone system operates with the Polycom VVX 601’s extensive call handling features, such as a busy lamp field, one-touch speed dial, and its do not disturb function. This device includes features like call waiting, transfer, hold, forward, and divert.
• Acoustic technology: Enjoy crystal-clear conversations with Poly’s Acoustic Clarity technology. The HD audio supports full-duplex sound with background noise suppression and echo cancellation.
• Unified communications: Use your desk phone to view and manage calendars, receive reminders, and see the presence status of your team members.

Grandstream GXV3275: Best for Its Video Conferencing Capabilities

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

• Video conferencing: The on-screen display has a video resolution of up to 720p and uses auto-focus, auto-exposure, and anti-flickering tools to provide top-notch video quality.
• Call management: The capacitive touch interface lets you add contacts to a downloadable phone book and see which employees are on a call before transferring a customer.
• Tablet functionality: Customize your phone by downloading third-party applications for the weather, social media, or calendars. Stream internet radio, use the built-in web browser, or create custom tools with Grandstream’s application programming interfaces (APIs) and software development kits (SDKs).

Grandstream GXP2170: Full-featured VoIP Phone for Handling High Call Volume

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

• Audio conferencing: Host a five-way conference call on your VoIP phone or skip the handset and put your meeting on speakerphone. You’ll get full duplex sound and HD audio for maximum clarity.
• Call handling: Five programmable soft keys and 11 dedicated function keys enable VoIP phone features on your office phone. Park or transfer calls and set up personalized ringtones.
• Contact management: View up to 500 call log records or press the dedicated Phonebook function key to access a downloadable phone book with up to 2,000 items.

Ooma DP1-T: Best for Ooma Home Office Users

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

• User interface: The Ooma DP1-T shows the status of your lines with lights. Red means a call is on hold, green indicates a busy line, and no lights signal an open line. Hard buttons let you access the contact directory, call logs, and 16-speed dial contacts.
• Voicemail: A red light appears at the top of the Ooma DP1-T phone if you have voicemail messages waiting, and the LCD screen shows the number of new voicemails you have (up to 99). Simply press the voicemail button and follow the prompts to hear your messages.
• Call flip: The Ooma DP1-T lets you quickly switch devices. Dial *44 on your desk phone, and it’ll automatically ring all devices for your extension simultaneously.

Grandstream DP720: Best Low-cost Cordless VoIP Business Phone Option

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.

Grandstream DP720 Features

• Mobility: The Grandstream DP720 has a range of 50m indoors and 300m outdoors. The rechargeable battery provides 20 hours of talk time and 250 hours of standby time.
• Call management: Create direct inward dialing (DID) call groups or download your phone book from the Grandstream cordless phone. It also supports three-way conferencing, call transfer, call park, and on-hold features.
• Multi-language: The Grandstream DP720 supports 19 languages, more than the 16 on Polycom models. In addition, the Grandstream DP720 includes languages not offered by other phone vendors, including Czech, Hebrew, Turkish, Arabic, and Serbian.

Cisco 7841: Most Energy-efficient VoIP Phone

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

• Fixed function keys: Easily access services with Cisco’s one-touch functionality, including messaging, directory, hold/resume, transfer, and conference features. Boost team productivity by programming keys for speed dialing and directory access.
• Hearing aid-compatible: Cisco’s 7800 series meets Federal Communications Commission (FCC) loudness requirements for the Americans with Disabilities Act (ADA). Also, the device’s dial pad is ADA-compliant for greater inclusivity and user comfort.
• Directory: The Cisco 7841 phone identifies incoming messages and categorizes them for users on the screen, making it a breeze to return calls using direct dial-back capability.
