The total revenue of the VoIP industry in America was $14 billion in 2019. It’s an industry that’s growing all the time and with good reason. Yet the public perception of how VoIP works is still a bit fuzzy.

One common question is “can a VoIP call a landline?”

The answer is yes, it can. You can call a landline number from your business VoIP line without any issues, but how does it work? Read on and find out!

How VoIP Connects to a Landline Number

Calling a landline number on your VoIP phone might seem odd. These are two different services, right? How can a digital number possibly connect to a traditional line?

The answer is through a clever interface.

The Difference Between VoIP and Landline Calls

When you call someone on a landline number, your voice is transmitted through the lines. You need a constant connection to the person on the other end of the line.

If the line drops, the call cuts out. That’s it.

When you call VoIP to VoIP, the data is sent as packets of information. This means that the line isn’t constantly kept open, instead, it is used when data is being sent.

So what’s the secret? How do you call a landline from a VoIP phone?

How Calling a Landline From a VoIP Works

When you call a landline from a VoIP phone, the call travels across the internet as far as it can. It then needs to enter the Public Switched Telephone Network, at least at present, as BT is switching this off in 2025.

When it enters the PSTN, it goes through a process called address translation. This changes the destination IP address to a phone number.

Do You Need to Pay Extra to Call a Landline Number?

Calling a landline number typically incurs extra charges. This is because your call still has to travel over the traditional phone lines for the duration of its journey.

However, VoIP systems can still save you money, whether you want one for business or your home. It’s not the only advantage of VoIP lines either. Let’s take a look at some more.
