When it comes to office telephones, even companies within the same industry or sector can have quite different needs. Compare a legal aid office to an upscale law firm that services high-profile corporate clients: the former might have a phone that constantly rings whereas the latter's telephone might ring four or five times an hour. One office might be relatively calm while the other is a madhouse.

Although office phones are definitely not one-size-fits-all, there are many unique systems available to cater to various needs and circumstances, whether your team telecommutes often, consists of only a few employees, or is consistently on the road and away from their desks. Read on to find the best office phone for your business.

Best Overall: Panasonic KX-TG7875S Bluetooth Cordless Phone

Panasonic is one of the better-known names in electronics and it doesn’t disappoint with this phone, particularly if your business regularly keeps you or your employees out of the office and on the road. Its Link2Cell technology links up to two smartphones so you never really have to be away from your landline. And it works both ways—your cellphone texts will show up on the Panasonic phone, too.

You can take calls just about anywhere thanks to this phone’s enhanced noise reduction. Plus, the power backup feature will keep it up and running even if the electricity goes out.

Best for Home Offices: Panasonic KX-TGF352N Corded/Cordless Phone

Panasonic has you covered if you work from home, too. The KX-TGF352N phone system comes equipped with a built-in baby monitor, so you can keep an eye out on your little one while you’re in your office area. And if your kids are older? Panasonic's noise reduction feature will stop any sounds nearby from interrupting your important conference call.

Just because you work from home doesn’t mean you don’t need top-notch business capabilities as well. This phone system includes a corded phone and three cordless handsets, all of which feature caller ID. The base unit has a battery backup that provides up to 13 hours of use and three one-touch dial buttons. There’s a call block button so you can ban those pesky telemarketers while you’re trying to take care of business. It also has an optional detector device so you can find your keys in a hurry or in an emergency. This one is perfect for both home and office use.

Best for Large Offices: AT&T CL2940 Corded Phone

If you work in a somewhat cavernous space—maybe the offices themselves are situated beside a warehouse or manufacturing area—this AT&T phone could be a great option. You’ll be able to see the CL2940’s display from a good distance away thanks to its extra-large screen. It also features caller ID so you can decide whether you want to pick up the phone or if that particular caller can leave a message. The caller ID feature includes a 65 name-and-number memory.

The buttons are extra-large, too, and the ringer is designed to be exceptionally loud, although you can tone it down with volume control. This model also offers call waiting and audio-assist speakerphone capabilities with volume control.

Xblue's X16 is perfect for small offices as it comes with four telephones. Each phone features a digital speakerphone, which is a nice touch. And if your office is a bit larger, you can buy additional phones for an all-encompassing system. This office phone system is expandable to up to six lines and 16 telephones.

The X16 also offers an “auto-attendant” for those inevitable times when no one is free to pick up the phone, and it will also create a “phone book” from your outgoing call log.

Best with Headset: VTech DS6771-3 DECT 6.0 Cordless Phone

Take business calls wherever you are in the office with the VTech DS6771-3 DECT 6.0 Cordless Phone. It includes a cordless headset for hands-free calls and is expandable to up to five devices. The office phone system doesn't skimp out on other features, either, with its caller ID share function that adds contacts from your landline system to your mobile phone, as well as its digital answering system voice guide. Plus, it can store up to 50 calls and 1,000 names and numbers in the phonebook directory. For versatility, the phone system allows connections with an outside line and up to two cordless handsets.

Even more, you'll know who's calling thanks to the telephone's caller ID/call waiting feature.
