Security and privacy are under extensive considerations currently and indeed so. Governments and corporations are more and more curious about getting your data, and phone calls are not any exception. Nearly daily, the headlines are full of the newest vulnerabilities, exploits, and scandals involving a data breach of some type.

It's no surprise that folks wonder if VoIP is genuinely secure. Some specialists even recommend businesses and customers to change back to traditional landlines. Now we'll take a look at some details and learn if VoIP is more or less secure than regular landlines.


At a technical level, each kind of systems is at risk of snooping. Especially by the provider and/or the government. That's primarily why most countries need a warrant – even for enforcement agencies – to wiretap any line.

The main distinction between VoIP and therefore, the PSTN is the method data handled, transmitted, and stored. Calls made on landlines travel through circuits, and thus the data is analogue. It's quite simple for somebody to listen in on a phone line call with comparatively low-cost instrumentation. However, they must have physical access to the wires.

VoIP calls are digital and travel over the web. So, hackers can snoop on your conversations although they're on the opposite side of the planet. All it takes is a few professional software and therefore the technical ability.

However, that doesn't mean VoIP is inherently at more security risk compared to analogue systems. Several specialists concur that a properly organised VoIP system is safer than your typical phone line. There are several reasons for this:

VoIP security makes the news

Security breaches create the headlines much all the time. The most significant consequence of those events is that corporations are taking notice concerning these issues. Not is security placed on the back burner till a problem crops up. Organisations are being proactive in securing their systems which includes the phones also.

Manufacturers and alternative infrastructure suppliers are consistently supplying patches and security updates. As long as users apply them and keep changing their hardware, your VoIP phones are secure.

You have additional security tools

Since VoIP data is digital, you'll be able to store it for later use. Sadly, that additionally suggests that criminals can capture those data packets. However, at the identical time, businesses have access to additional security tools to secure the phones with end to end coding, ever-changing passwords at regular intervals, securing the endpoints (computers, SIP phones etc.).

You can phase and segregate VoIP traffic

Some individuals believe that VoIP is insecure as a result of it travels over the net. Whereas regular phone calls have their network. But again, companies have a lot of options once it involves securing VoIP calls.

For instance, you'll be able to segregate VoIP calls from the remainder of your business network through VLANs. Meaning VoIP calls don't get contact with regular data packets. That creates it more comfortable to isolate issues and verify if somebody has hacked into your network. That additionally suggests that hackers cannot compromise the phones by breaking into alternative connected systems.

Some firms even move to the extent of getting a separate physical network for their phone calls. That means you've got complete management over security. What happens on one network doesn't ought to impact the opposite the least bit.  

Should you upgrade to VoIP or use landlines?

When it comes right down to it, there's no such factor as a secure telephone. No supplier would be foolish enough to say that their hardware, software or tool is untouchable. Even if it were, it's solely a matter of your time before somebody comes up with some way to interrupt in. If not a technical loophole, there's continuously the human element. 

Perhaps the most considerable advantage of landlines is that almost all users relied on security through obscurity. Unless somebody vitally needed to snoop on your calls, you were comparatively safe. With VoIP, security problems take centre stage. That's a decent factor. Information is power and therefore, the additional you recognise a few drawbacks, the higher your odds of fixing it.

Delaying the upgrade to VoIP for your business due to security considerations isn't precisely the best call. What you must be doing is watching your systems and ensure to mend security problems before they become broader issues.
