Wizix TechVoIP

If you’ve been considering switching to VoIP (Voice over Internet Protocol), you probably have a few questions. Many business owners wonder “How does VoIP work in the first place?”, “How much bandwidth will I need for VoIP?”, “Is VoIP secure?”, and more. Today we’re answering some of the most frequently asked questions about VoIP so you can make a confident decision. 

Frequently Asked Questions About VoIP

1: How Does VoIP Work?

VoIP works by converting analog voice signals into digital data that can be transmitted over the internet. When you make a call using VoIP, your voice is first converted into digital data using a codec. The codec compresses the voice data by breaking it down into packets and transmits it over the internet to the recipient’s device. 

Then the packets are reassembled and converted back into analog voice signals for the recipient to hear. This process of compressing and decompressing voice data ensures that the call retains high quality audio. 

2: Will VoIP Work without an Internet Connection?

VoIP uses the internet to transmit digital data from one device to another, and it will not work if the internet is down. If you’re considering switching to VoIP, you must have stable, reliable internet service. 

3: How Much Bandwidth Does VoIP Use?

It’s also important to have enough bandwidth to avoid dropped calls and connectivity issues. The amount of bandwidth VoIP requires will vary depending on the number of simultaneous calls and other factors. But in general, VoIP uses less bandwidth than other data-intensive applications like video streaming. On average, a single VoIP call uses between 64 and 128 kbps. 

4: Does VoIP Need a Phone Line?

No—unlike landline phone systems, VoIP does not require a telephone line. Instead, it uses your internet connection to make and receive calls. This means there’s no need to install any additional hardware or pay for a separate phone line, making VoIP a more affordable option compared to standard or wireless landlines. All you need is a VoIP provider and a reliable internet connection. 

5: Can I Keep My Current Phone Number with VoIP?

Yes! In most cases, when you switch to VoIP you can keep your existing phone number if you want to. You won’t have to worry about potentially losing business or confusing your clients and customers by changing your phone number. As long as you choose a VoIP provider that offers number porting, like WiZiX Technology Group, you can keep your number.   

6: Is VoIP Secure?

As long as it is configured properly and used on a secure network, VoIP is completely secure. However, it can be vulnerable to hacking and other security threats unless you take precautions. You can secure your VoIP phones by installing a firewall, monitoring phone usage, creating a strong password policy, and choosing a provider that uses encryption.
