Which office phones are best?

Landlines are mostly a thing of the past, but if you work in an office, they can be useful for your business. Luckily, there are some excellent models out there with great high-tech features that can make your life easier. 

The size of your office, the number of lines you need and your budget will go far in determining what model is best for you. A top pick is the AT&T 4-Line Expandable Corded Phone, which has all the options you’ll need for a small business.

What to know before you buy an office phone

Traditional phone line

How do you receive your phone signal? If you go through the telephone company or a PBX (private branch exchange) and connect through their public network, a traditional office phone is a good fit. You’ll be able to hook up multiple phones and handle multiple incoming and outgoing calls. If you have a bigger office and need to handle more than one call at a time, you will need a phone hardware system. 

VoIP phone system 

Unlike a traditional phone line, a VoIP (voice over internet protocol) system goes through your internet connection. You don’t need a PBX, but you can still get many of the same features while being able to effectively manage incoming and outgoing calls. 

What to look for in an office phone

LCD screen

Display screens on office phones vary in size and function, but most will provide caller ID information, along with any other system alerts.  

Speed dial

Dial the numbers you call frequently with the touch of a button. Most phones can store between 10 and 40 numbers on the speed dial. 


You’re not going to be able to answer every call, so luckily, most office phones have a custom voicemail feature. This way callers can leave a message and you don’t miss out on any opportunities or potential business. 

Conference call

When you need to speak with more than one person at a time, the conference call feature allows you to loop in multiple parties. Most quality office phones have a speaker and microphone, so you can gather in a conference room and speak with multiple people on the other line. 

How much you can expect to spend on an office phone

There are many models of office phones that are relatively inexpensive and offer features that can benefit your office or business. 

A basic model with no call management features ranges from $10-$25. A mid-range phone can run you up to $75 but offers hold and transfer options, caller ID and speed dial and display screens for updates. A top-of-the-line office phone can cost between $100-$250. It can handle multiple calls simultaneously and offers auto-answer features.

Office phone FAQ

What are the best features to have in an office phone?

A.  Four favorite features on an office phone include:

  • Headset jack for hands-free calls
  • Speakerphone for group calls
  • Speed dial for commonly made calls
  • Battery backup options

Does an office phone need to be able to handle many incoming lines?

A.  Office phones that can only handle one call at a time are good options for small businesses with limited phone traffic because it keeps down the cost of your bill. For a growing office, purchasing a phone that can handle four or more calls at a time ensures that you don’t miss any incoming calls. Evaluating the needs of your business prior to purchasing an office phone is beneficial so you select the model best suited for your office and your budget.
