Is VoIP Reliable: Understanding The Technology

VoIP (Voice over Internet Protocol) is a telephone system that connects to the internet through a phone line. When you use Voice over IP, you are connecting to a hosted PBX away from your office.

VoIP technology converts phone calls into a digital signal and sends them through high-speed internet connections to a VoIP service provider. Calls are then relayed to other telephone companies via the Public Switched Telephone Network (PSTN).

Calls made over IP can originate from a desk phone, a conference phone, or even an app. A real-time communication protocol called Session Initiation Protocol (SIP) is used as the underlying technology. Skype, Google Voice, and WhatsApp are examples of popular personal apps that use VoIP.

VoIP allows you to control the path to which incoming calls are forwarded. Unlike traditional business phone systems, you are not limited to one line per desk phone. Using any mobile phone or softphone, you can make calls anywhere.

The only requirement for VoIP is a stable internet connection, which is currently available to more than 14 million Australians.

VoIP Vs. Traditional Landline

Your main difference is you don’t have to deal with the local landline service company. In contrast, an independent carrier is often responsible for providing VoIP services.

Landline phone systems can only be used in areas where they are installed, which is another huge difference between them. This limitation is not present in VoIP solutions. Physical location does not matter with VoIP.

With traditional phone service, you have to run a physical cable system to every device. For offices, this refers to bulky networking and telecom equipment kept in a server room. This is also known as a PBX (Private Branch Exchange).

VoIP telephone systems are cloud-based. In your office, there is no need for a server room, and you don’t need copper wires snaking through the room either. Connections to VoIP telephone systems are virtual – hosted on the internet.

A VoIP system requires a wide range of phones and devices. Network connections are required by every office phone and mobile device, whether Ethernet connections or Wi-Fi. In addition to offering more features than landline telephones, IP phones provide excellent audio quality.

Which Is More Reliable, VoIP or Landline?

On-site telephone systems have been around for over one hundred years, but we don’t tend to question their reliability. But in terms of reliability and uptime, there are many factors to consider.


A provider’s uptime is the percentage of time they are online and available. In terms of percentages, an uptime of 99.999% means that only six minutes a year are lost to downtime. Uptime is defined as having five nines in the IT industry.

VoIP providers, carriers, and device reliability play a part in VoIP phone system uptime. A redundant network of data centres is used by cloud PBX providers to achieve such a high uptime. Servers like these are known as Points of Presence (or POPs).

Occasionally, landline phones can go down due to wire cuts, power outages, or weather conditions. It can take the phone company hours or days to restore service. Additionally, the cause of such problems might not always be obvious. You may experience unreliable unified communications due to faulty equipment or other reasons beyond your control.

VoIP is possible as long as you have regular access to the internet. Even if your internet goes down, you can still make phone calls on your cellular networks until the issue is resolved. When the power goes out, or the internet is down, VoIP still works.

International calls

International calling is a must if your business serves customers abroad. Dialling internationally can be a bit intimidating with different country codes and prefixes. It is possible to lose a lot of money by dialling the wrong number.

International calls over the Public Switched Telephone Network (PSTN) are subject to costly long-distance charges that can be more than a dollar per minute. Several businesses are not able to conduct international business calls because of the lack of extra cash. These fees are prohibitive even for business plans. VoIP offers the advantage of global calling.

A reliable VoIP call can be made for just a penny per minute since the calls are made over the internet. Toll-free numbers and virtual phone numbers are other options for businesses to offer their customers an affordable way to communicate with them.

Think of a call centre connected to a remote team. VoIP allows you to accept and place calls as if you were in the same state. You won’t have to pay long-distance tolls. There is only one requirement: a reliable internet connection.


Whenever VoIP is discussed, security comes up frequently. When CIOs consider a new business phone system, they consider data security and business continuity.

Traditional phone lines could be tapped by unscrupulous people, especially if the wiring is accessible. Additionally, it is possible to exploit some traditional PBX systems for making unauthorized calls.

The security standards of cloud PBXs ensure that your calls are secure. Data centres are constantly monitored and can withstand natural disasters.

Encryption of calls is a relatively new feature of VoIP. With TLS and SRTP, data exchanges between SIP phones and the cloud PBX are encrypted.

Security practices aren’t exclusive to large businesses. Customer data is often protected by the terms of the agreements.

VoIP is more secure than landlines when it comes to security. Our servers are monitored around the clock by qualified third parties who check for vulnerabilities. In the case of landlines, it is your responsibility to ensure no one has access.

Call quality

People switch to VoIP because of the quality of their calls. Calls using VoIP are always better than traditional landline systems, so you’ll never want to go back.

The development of audio codecs enables better voice quality. Virtual phone systems and apps use these technologies. HD voice codecs offer twice as much bandwidth, so callers can hear a greater range and sound quality on every call.

When audio conferencing into a meeting, call quality is even more of an issue. All parties on the call become quite irritated by echoes, background noise, and mobile phone calls. Voice over IP’s advanced features make a world of difference.

Having wiring or a handset issue on a landline telephone or cell phone is very obvious and a distraction. Today’s VoIP desk phones, conference phones, and app advancements make calls enjoyable for all participants.


Even though a phone system’s redundancy may seem worrisome, in these times, it is not. Call forwarding between team members or using video conferencing at home has become much more practical.

This redundancy is built-in to VoIP communications. Your calls stay online regardless of network interruptions such as jitter, which is common for IP-based networks.

There is a single point of failure with landlines. VoIP provides you with a backup option at all times. You can also use a free VoIP app on your smartphone to accept calls when that doesn’t work.
