You can get two or four-line phones from just about anywhere. But what about supervisors and teams who need to field and make a flurry of calls simultaneously?

Nextiva offers three models of desk phones that each can handle 12 lines. We think the X-835 is the best for most people’s needs, with its blend of affordability and customization.

Above all, that 12-line capability is the big selling point and rightfully so. But its 2.8-inch color LCD screen allows for a multi-page interface so you can program the eight buttons flanking it in multiple ways.

Its ethernet ports can handle up gigabit connections and allows for the phone to be powered over ethernet. The X-835 can be Wi-Fi enabled with a USB dongle.

Other key features include:

  • Speed dialing
  • RJ-9 headset input
  • One USB input
  • Modular expansion capability
  • Three-year warranty

If your office or team needs way more than just two or four-line capability, go with the Nextiva X-835 today.

Call recording, screening, and intercept mean that you don’t get any calls you don’t want. Voice prompts and memo recording allow you to direct people where they need to go before you even answer the call. The system does have caller ID and call waiting on its display, but you need a subscription through your phone company to access the feature.

This system also works best for businesses that have someone ready to answer the phone. It only has 12 minutes of message storage on its digital answering system.

Despite its lack of other features, the AT&T 2-Line Corded Phone is hearing aid compatible. It also has a multilingual set up in English, Spanish, and French.

At $79.95, this option works well for businesses that need an affordable, basic option for few people. It’s not ideal for companies that want to expand.

How to Find the Best Multi-Line Phone System for You

Running a small business means serving both your customers and your team. If your multi-line phone system lacks features your team needs, they can’t do their best work. When you need a multi-line phone system, consider the below factors to get the maximum capability and efficiency for your business.

Manufacturer Reliability

No matter what type of product you’re looking for, you should buy from a reputable manufacturer. Reliability can mean getting the help you need when you need it through company support. Ideally, it also means you get lasting products.

For example, Panasonic is a well-known electronics company. You should be able to expect above-average service and product quality from them. When you’re running a business, getting products from a reliable company can help your business build a good reputation, too.


You want a scalable phone system so that you don’t have to get a new one as soon as your business starts to grow. Unless you plan to stay a one-person operation, you should get a phone that supports at least five lines. Many of the systems on this list support up to 20 lines.

A futureproof phone system might cost a little more. Still, when your business doubles or triples in size later on, you’ll be grateful not to spend more money on a phone system that fits it.

Transfer Features

Transfer features shouldn’t be limited to transferring calls to the office down the hall. Look for mobile transfer features. Many phone systems allow you to transfer to a limited number of mobile phones.

This feature becomes especially useful if you have employees who work from home or out in the field. It also makes for better business flexibility and allows employees to remain available when they’re not physically in the office.

Strong Basics

You’ve probably heard that a solid foundation is more important than fancy features. It’s true. When you get a phone system, you should have features like:

  • High-quality sound and video
  • Voicemail capability
  • Intercom and conference calls
  • Forwarding and transferring
  • Hold and mute
  • Sending voicemail messages to email

You also want enough lines to keep your business running. Plus, good support from the manufacturer makes all the difference when you have a problem. Before you check out your phone system’s extras, verify the quality of the basics.


Your multi-line phone system can make or break your small business. It can define your service quality and help or harm your reputation when customers want to contact you.

Make sure you have all the basics, and only go for extra features that directly benefit your business. You want something affordable but which has all the capability you need for high-quality service.

Determine your needs before you buy. For a scalable, futureproof option, Panasonic will serve you well. On the other hand, AT&T offers a simple solution for businesses with just one or two people. Small businesses come in all shapes and sizes, so tailor your multi-line phone system to yours.
