Best Office Phone Systems 2024: Comparison Table 

Here’s a quick comparison of the top ten phone systems for offices in 2024 to help you choose the best one for your needs faster:

Why Do I Need a Good Office Phone System?

Clear and precise inter-communication remains the key to success for all businesses. Seamless communication ensures that your business units can work with each other to implement enterprise strategies and achieve objectives successfully.

One of the main tools that will help your workers communicate is the office phone systems which are either analog or software-based communication platforms enabling your employees to communicate using multiple channels and devices.

Office phone systems have several direct benefits for your business.

Your customer service improves as all your departments communicate to remain on the same page. Moreover, the ability to answer calls anytime and anywhere reduces stress on your workers while allowing your value-adding business processes to flourish.

And finally, since most of these systems do not require costly on-site installations, you also save a lot on costs.  

How do Virtual Office Phone Systems Work?

VoIP office phone systems do not use traditional hard-wired telephone lines. They use the internet connection to connect calls, specifically Voice over Internet Protocol or VoIP.

Irrespective of where you are calling from, virtual office phone systems use specific VoIP codecs to convert analog sounds to high-quality digital audio channels for superior call quality.

Most virtual office phone system providers host your calls on their VoIP-based networks. They even have redundant systems as a backup if the main network goes down due to inclement weather conditions.

This ensures that your business communication channels remain open irrespective of conditions.  

How to Choose an Office Phone System?

Choosing office phone systems for business depends on several factors: 

Internet Availability

If, for some reason, your business does not have or cannot use high bandwidth internet, you can opt for traditional landline systems. These are just like the legacy phone systems that are supported by the local phone service provider.

They use the telephone company’s traditional copper wiring called the public switched telephone networks (PSTNs) and are run using an on-premises private branch exchange (PBX).

These systems are time-tested, reliable, and still in use across many businesses worldwide owing to their ease of use.

However, due to the digital revolution, they are fast becoming obsolete, meaning it may be difficult to find a vendor and repair them in case of disruptions.  

Remote Connectivity

If your business has a lot of off-site employees, staying in touch with them will be difficult with legacy landline systems. Instead, your business can opt for a virtual phone system that works as an extensive call forwarding solution.

Whenever a customer or another employee calls a central contact number, the calls are forwarded to the employee’s home or mobile phone instead of a desk phone.

This system allows employees of diverse geographies to stay connected using standard phone systems. They also feature other benefits like online faxing, toll-free numbers, call screening, call forwarding, voicemail, and automated receptionists.

However, they still use the standard phone lines and depend on their availability to keep the communication channels open.

Internet-based Systems

If you want to invest in digital solutions that use the same internet line you use for other purposes, you can opt for a VoIP-based virtual office phone system.

Even though these do not use the same phone systems, they still provide all features that traditional PBX-based legacy systems provide, including call queues, automated attendants, and even computer integration that allows voicemails to be emailed to the recipients.

There are two main types of VoIP-based office phone systems – on-premises and cloud-based, with the cloud-based offering gaining significant popularity in recent times.

The main benefit of having a VoIP-based office phone system is its simplicity and control. Your office IT team is fully capable of maintaining and servicing the system. 

However, you should practice caution while choosing a VoIP-based system, depending on the cost.

You can either opt for a high-upfront cost-based service where you own all the equipment or just a VoIP service provider where you pay monthly usage charges.
