Everything you need to know about VoIP phone systems and Wi-Fi


These days, everything is connected to the internet. Your thermostat, fridge, video game consoles – you name it, it’s connected to WiFi. And considering the worldwide VoIP industry reached $13.7 billion this year,1 it’s no surprise that many of our customers want to know if they can use their VoIP phone system over WiFi.

We consider this to have a somewhat complicated answer because the question can mean different things to different people. Regardless, let’s dive into the subject and look at how business VoIP phone systems work with WiFi.

Do VoIP Phones Work Over Wi-Fi?

Yes! Wi-Fi IP Phones certainly work and are very popular especially in remote homes or smaller satellite offices.  There are popular brands like Poly and Yealink that offer wireless options.

Do IP Phones Need a Wired Internet Connection?

IP Phones can work over a wired or wireless connection.  VoIP phones work best over a wired connection but wireless is certainly becoming more popular to save one time cabling costs.

What Are the Challenges of Using VoIP Over WiFi?

Around 6% of businesses say they experience poor call quality when making calls with VoIP phones.2 As we mentioned above, connecting your IP phone to a wireless device can result in several call quality issues. 

A few challenges of using VoIP over an unstable WiFi connection include:

  • Jitter - Jitter refers to the variation in the delay between when a data packet (such as your voice call) is sent and received. This can cause the audio to sound choppy or fragmented.

  • Packet Loss - Packet loss occurs when data packets are lost during transmission and can cause audio gaps, stuttering, and distortion.

  • Latency - High latency can cause an audio delay or echo, making it difficult for customers and employees to have a natural conversation.

To avoid these challenges, we recommend using a hard-wired connection from the back of your IP phone, plugged directly into your main router. If that’s not possible, make sure your wireless device has a consistent, high-quality connection to a router. Wireless card differences don’t make a huge difference since VoIP doesn’t tax your internet needs much.

Are There Wireless IP Phones?

Here’s where people tend to mince their words and get confused. Yes, there are wireless IP phones. But they’re similar to wireless phones you may have in your house, as opposed to something like a smartphone.

You still have to connect wireless VoIP phones physically to get an internet signal, and only the handset itself is wireless. Essentially, they’re connected to the phone via an ethernet wire and are not truly wireless.

IP phones work by using a cell phone to access your business VoIP phone system via a mobile application. You get all the critical features this way, including transfer commands, voicemail, and outbound caller ID, making it an ideal solution for work-from-anywhere employees.

Final Thoughts on WiFi and VoIP Phone Systems

Most offices prefer a wired network to guarantee reliable phone calls.  In our experience, small offices under 15 people and remote offices go wireless and there are ways to get the wireless functionality you need to prepare your business for the new world of work with a cloud phone system.
