Advantages and disadvantages of using VoIP

What’s VoIP?

VoIP stands for Voice over Internet Protocol. VoIP is also known as IP Telephony (Internet Telephony), Internet Calling (Internet Calling) and IP Telephony (Internet Telephony). It’s an alternative method to making phone calls, which can be either very inexpensive or completely free. Internet Protocol (IP), was initially designed for data networking. Because IP has become a global standard in data networking, it has been adapted to voice networking.
VoIP has many advantages

Voip has many advantages for both residential and small office/homeoffice users. A VoIP phone service may be the right choice for you if you have an internet connection that is fast.

Low cost

This technology can lead to greater financial savings. Web and video conferencing can reduce travel costs and training costs. You can make free PC-to-PC calls from anywhere in the world if you have an Internet connection (DSL, cable) There is usually an additional charge to establish a PC-to phone connection. However, it will likely be cheaper than regular phone service.

Low taxes

VoIP phone services are not subject to heavy taxes because they can be carried over the Internet. You and your family could save significant money by choosing a VoIP provider.


VOIP is a more affordable alternative to regular phone service, which often charges extra for additional features. Call forwarding, call waiting and voicemail are just a few of the many features included in VOIP phone service. You can also send documents and pictures while you’re talking on the telephone.

VoIP phones can be integrated with other services over the Internet including message and data file exchange, video conferencing, managing address book, and sharing information about who is calling (e.g. Friends and colleagues are available online to anyone who is interested.


VoIP Ireland allows for advanced bandwidth and video-conferencing at a low price.


VoIP is not location-dependent, unlike its forefathers PSTN. This is an important fact to remember about VoIP. VoIP doesn’t care if you call your supplier in Indonesia 1,000 miles away or your business partner in another part of the country. It doesn’t matter if it is cheaper or faster.

No extra cables, no extra cost

A VoIP phone number is portable, unlike a regular phone number. A virtual number is commonly used to refer to a VoIP phone number. It can be taken with you wherever you go.

Even if your office moves to another state, your phone number can still be with you. You can take your entire business along with you when you travel.


You will receive a converter when you select a VoIP provider. This converts your regular phone to use VoIP. The converter will include your phone number. You can carry your phone converter with you wherever you go, as long as there is an Internet connection. Your telephone number is located in the converter and not at your home/office. This allows you to choose any area code as your number. For a small fee, some carriers allow you to have multiple phone numbers in different areas. This is called a virtual number.
VoIP’s disadvantages

There is no service during power outages

It is impossible to maintain service using the current through the phone line with IP phone during a blackout. Therefore, VOIP service is not available when there is no power. An uninterruptible power supply (or a generator) must be installed in order to use VoIP during power outages.

Calls for emergency assistance

Your location can be traced using traditional phone equipment for emergency calls. Because voice-over-IP calls are essentially data transfers between two IP addresses and not physical addresses, there is no way to trace where your VOIP call originated from.


Because VOIP depends on the Internet, the quality and reliability your broadband Internet service as well as the limitations of your computer will affect your VOIP service. Poor Internet connections or congestion can lead to distorted or garbled voice quality. You may notice a dramatic drop in voice quality when you use your computer simultaneously with a computer VOIP phone call.

This is especially true in networks that are extremely congested and/or have long distances between ends.

VoIP Voice Quality

VoIP can improve Voice Quality slightly, but not always. Your broadband connection, hardware, service provider, destination, and VoIP QoS (Quality of Service) all play a part in your VoIP QoS. While VoIP is becoming more popular, many people still complain about hearing Martian and having to wait for an answer.


Most prominent security concerns regarding VoIP include identity theft, malware, viruses, malware, denial-of-service, spamming call tampering, phishing attacks, and virus and malware.
