1. Nextiva X-885: Best Overall Multi-Line Phone
- Price: $190
- Lines: 12
The Nextiva X-885 is the best multi-line phone in our in-depth research because of its modern design and its native integration with Nextiva, providing advanced VoIP features built in. Plus, with 12 lines, it’s the most flexible option on this list, making it perfect for front desk staffers.
The Nextiva X-885 is a bit more expensive than other options on this list, which makes it less accessible for smaller businesses. On top of that, the device doesn’t have Wi-Fi functionality built in, so you’ll have to pay for a USB dongle that can do that for you.
- Key feature: The 4.3-inch color display provides a modern feel while being easy to use.
- Pro: The phone system natively integrates with the Nextiva VoIP service, providing access to advanced features like visual voicemail.
- Con: Connecting to Wi-Fi requires an additional dongle, which you’ll have to pay for. It does connect via Ethernet for no additional charge.
- Pricing: At $190, the Nextiva X-885 is a bit more expensive, but the added features and premium design are worth it.
2. VTech DS6151: Best Two-Line Phone System
- Price: $88.95
- Lines: 2
If you need a lower cost phone system with fewer lines and a bit more flexibility, the VTech DS6151 is the right fit for you. It offers only two lines and costs just $88.95, which is less than half the cost of the Nextiva X-885. It’s also a cordless option, so you aren’t tethered to a base when you make calls.
Most notably, the phone system uses DECT 6.0 digital technology to ensure there is no interference with any other wireless networks or electronic devices in the building, improving quality and security.
The VTech DS6151 is a traditional phone system, though, which means you won’t get all the VoIP features like AI summaries and visual voicemail.
- Key feature: With DECT 6.0 digital technology, the VTech DS6151 exclusively makes calls that are secure end-to-end encrypted and have crystal clear audio quality.
- Pro: The VTech DS6151 can add up to 12 cordless handsets to the system on a single phone line, so it can scale with you as your business grows.
- Con: Because the VTech DS6151 is a traditional phone system, the design and functionality are a bit less modern than other options on the list.
- Pricing: The VTech DS6151 is the most affordable phone system on this list, costing only $88.95.
3. AT&T ML17939: Best for Speakerphone Conversations
- Price: $104.95
- Lines: 2
The AT&T ML17939 is a two-line phone system that is a bit more expensive than the VTech DS6151, despite being a corded option. However, it offers more advanced features, like Clearspeak technology, for seamless speakerphone conversations, and a built-in digital answering system, with 12 minutes of recording time per line.
Like the VTech DS6151, the AT&T ML17939 is a traditional phone system, which means you won’t get access to any advanced VoIP features. But with a 50-name and number phonebook directory and streamlined dialing tools, you can still get a lot out of this phone for your team.
- Key feature: Clearspeak technology allows users to have high quality speakerphone conversations directly from the base without using the handset.
- Pro: The system is easy to use, providing speed dialing tools that allow you to simply push a single button to speak with one of 50 contacts.
- Con: The traditional, corded phone system is a bit outdated in 2026, providing limited flexibility for professionals working anywhere but their desk.
- Pricing: The AT&T ML17939 is a bit more expensive than other traditional, two-line phones at $104.95, but provides some advanced functionality to make up for it.
4. Cisco CP-8861: Best for Larger Businesses
- Price: $172.95
- Lines: 5
The Cisco CP-8861 is a robust, versatile, and expensive phone system. It’s ideal for larger businesses, because it can scale with your growth, allowing for up to three Key Expansion Modules (KEMs), which will turn your phone system into an all-in-one command center for your front desk staff.
Beyond that, it comes with a large, 5-inch display, built-in Wi-Fi and Bluetooth for quicker connections with headsets, and compatibility with VoIP services for advanced features, like AI summaries.
There are some downsides, other than the high price tag, though. It’s a larger device than most phone systems at 10 inches wide, so you’ll need a big desk to house it. The Cisco CP-8861 also has some hefty power requirements, because it’s designed to be powered via Power over Ethernet (PoE).
- Key feature: The Cisco Intelligent Proximity feature allows users to connect their smartphone to the device to transfer contacts and call history.
- Pros: The massive 5-inch display and integrated Wi-Fi and Bluetooth make it very easy to use for employees.
- Cons: The phone system has high power requirements with Class 4 PoE needed, which means you might have to upgrade your office infrastructure.
- Pricing: The Cisco CP-8861 is notably more expensive than competitors at $172.95, plus you may want a monthly charge for Cisco Unified Communications, for full functionality.
5. Panasonic KX-TG9582B: Best for Cell-to-Landline Communication
- Price: $240
- Lines: 2
The Panasonic KX-TG9582B is a two-line traditional phone system that, despite lacking VoIP compatibility, can connect up to four smartphones to accept calls with its Link2Cell technology. This makes it a perfect solution for smaller businesses that do business on the go.
The Panasonic KX-TG9582B is expensive, but it does come with an additional handset included in the price. More notably, that handset has a 75-minute backup battery, so if the power goes out, you’ll still be able to make calls.
- Key feature: The Link2Cell feature allows users to connect four smartphones to one phone system.
- Pros: The battery backup on the Panasonic KX-TG9582B means you still get 75 minutes of call time, even in a power outage.
- Cons: Despite the mobile connection options, it is a traditional phone system, which means it is not compatible with VoIP services.
- Pricing: The Panasonic KX-TG9582B is the only phone system on the list to break the $200 barrier, at $240, but it does come with one additional handset included, so does still represent good value.

What’s the Difference Between Traditional and VoIP Phone Systems?
Traditional phone systems connect to analog infrastructure like landlines and require specific hardware to make and receive calls. These systems do not require the internet to make calls and don’t typically come with advanced features, like AI summaries or visual voicemail.
Voice over Internet Protocol (VoIP) phone systems use the internet to make calls and can be used on mobile devices and desktop computers.
Check out the breakdown below comparing some of the key differences between traditional phone systems and VoIP phone systems.
| Traditional | VoIP |
|---|---|
| Large upfront cost | No upfront cost |
| High maintenance fees | Low monthly fees |
| Reliable infrastructure | Modern technology |
| Specific hardware requirements | Works on desktop and mobile devices |
| On-site installation | Cloud-based platform |

Who Are the Best VoIP Providers?

Methodology: How We Pick Multi-Line Phone Systems
Our team tested products and studied online reviews in order to rank each phone system on a five-star scale based on seven different criteria important to multi-line phone systems. Systems that delivered the most functionality while remaining cost-effective and easy to use rose to the top.
Here’s a breakdown of the metrics by which we evaluated the top multi-line phone systems:
- Cost factors: Does the phone system offer a good value relative to its price?
- Features: Can the system support typical business needs?
- External connections and integrations: Will it work easily with existing systems?
- Customer support options: Will you get the support you need?
- Security options: Is the system safe and private?
- Scalability: Can the system easily keep up as a business grows?
- Customer review scores: Does the system satisfy its current customers?
Check out our in-depth research guide to learn more about how we test and evaluate software for small businesses.
Our top pick is the 12-line $190 Nextiva X-885 system, which offers a 4.3-inch LCD color display, HQ call quality and a suite of versatile, useful features — certainly enough to justify the high cost.
But if you’re looking for a simple two-line system, we recommend the $88.95 VTech DS6151 for its features, ease of use, and expandability of up to 12 stations.
Whatever model you settle on, you’ll more than make up the cost in savings by avoiding hours of phone tag and hunting for the right client number, particularly if you opt for a cloud-based VoIP option.
