What to Look For in VoIP Business Phones

Before we launch into VoIP Telephony Top 10 in 2023, it’s worth examining your requirements so that you can effectively evaluate all the possible options.

With a VoIP phone system, you’ll benefit from several functions that wouldn’t be available with a traditional landline phone. For example, advanced call handling or video conferencing might be possible depending on your phone system. But it’s important to establish the functionality you and your team need; otherwise, it’s easy to waste time and money installing an elaborate phone system with features you don’t even need.

On the other hand, it’s important to be aware of the traits you might need in a phone system as your team grows. While you’re predicting and anticipating the key characteristics you might need in a VoIP phone, there are a few essentials you might want to look out for, such as the following:

1. Price

It’s often number one on the list, as businesses want to ensure their phone choice supports their ROI, as with any other investment. Your phone choice needs to fit within your business’s budget and offer the functionality to help you reach your business goals. There’s no need to pay for excessive bells and whistles if you need the basic functionality of VoIP calls, so when comparing your options, it’s important to think of value rather than the cost to ensure you make the right choice.

2. Audio Quality & Reliability

It’s worth remembering that it’s not just your connectivity that could impact the quality of your phone calls. For most modern businesses, call quality should be a non-negotiable, so choosing a phone system built with audio clarity and quality at the core is key. Ideally, look for a phone model that offers HD voice quality and a service level agreement (SLA) that gives you real peace of mind regarding your phone system’s reliability.

3. Connectivity

VoIP telephony helps you benefit from the enhanced connectivity of the modern working world. That means connectivity should be a key consideration when choosing a phone system for your business. Phones that offer Wi-Fi connectivity will come in very handy, regardless of your other requirements, especially if you are looking for a cordless phone model to replace old corded handsets, which won’t require you to link them up to your router via ethernet. Likewise, VoIP phones with built-in Bluetooth capabilities may also be an advantage, as your users can use hands-free headsets and will benefit from a mobile device in a physical desk phone.

4. VoIP Phones – Hardware Features & Functionality

As we mentioned, it’s important to assess the core functions you’ll need in a VoIP phone and those you may require as your business grows. The best VoIP phones should offer you much more capabilities than a traditional office desk phone. For example, you might want to be able to route or block calls, or you might want to hold conference calls or video meetings with your chosen hardware. HD video might be essential for your team now, or it might still be a nice-to-have bonus feature, but as internet connectivity becomes ever more reliable, video compatibility is something you may want to consider.

5. VoIP Service Compatibility

For the most part, modern VoIP phones are compatible with all VoIP software. However, it’s important to check whether your VoIP provider requires or favors certain models of phones. Choosing a phone model that’s compatible with your service provider will mean you can benefit from the full selection of capabilities that VoIP telephony offers, with the reliability of a full VoIP ecosystem.
