    With VoIP, you can make phone calls via the internet rather than using a traditional landline or cellular network. There are several names for this sort of technology. Broadband telephony, broadband internet telephony, internet protocol telephony, and IP telephony are all on the list.

    It's understandable if the phrase "VoIP" is foreign to you. But, it's likely that you've used this technology without even realising it. VoIP is used by many of today's most popular messaging apps to allow users to make phone calls to one another.

    Throughout the past few years, VoIP technology has seen a meteoric rise in adoption. It's more popular than traditional phone service since it's less expensive, more flexible, and provides more value to its users. VoIP enables its users to engage in digital forms of communication, including video calling. Therefore it's no surprise that it's replacing older forms of communication.

    People no longer need to use traditional phone systems, as this technology allows them to do it via the internet. The most significant benefit is the independence from local phone infrastructure and signal quality when making international calls. Such a flexible advantage and simple means of communication is crucial in the current climate of lockdowns and restrictions caused by the coronavirus.

    Like any other technology of its kind, VoIP does have some drawbacks. It's important to consider the system's downsides with its advantages before deciding whether or not to implement it.

    FAQs About VoIP

    You can now use any phone to make Voice over Internet (VoIP) calls. Simply wait for the dial tone, and you're ready to make and receive calls.

    VoIP allows for normal phone calls through the internet with all of the options usually enjoyed by business's traditional PBX systems including voicemail, call waiting, call forwarding, conference calling, caller ID, and more. In addition, VoIP software integrates well with desktop computers for use as “softphones”.

    It normally occurs over connectionless or packet-switched networks. VoIP uses packets to send audio across a network, these packets can sometimes take a different path than intended and results in a call with poor quality or scrambled audio.

    If the ISP that's supporting VoIP goes down, the VoIP system can automatically be switched to the other ISP so there's no interruption of phone service. Of course, having what is essentially redundant Internet service will increase your Internet connection costs.

    Essentially VoIP systems are simply a subcategory of IP technologies. A VoIP phone means that that phone system is designed to transfer voice traffic via the internet connection exclusively. In contrast, IP technology can transfer voice, fax and messaging and other data traffic.

    Types of VoIP

    Phone calls are converted into digital data packets and sent via the internet, which is the primary emphasis of most VoIP hubs. This can happen in several different ways. The simplicity with which each can be implemented and maintained varies. Let's look deeply at the various VoIP technologies available to assist you in choosing the best one for your company.

    Possibility of Integrated Access

    Functions of access, such as landlines, were incorporated. The only real difference is how easily the VoIP software works with your existing phone infrastructure. With integrated access, organisations may use advanced communication options without replacing their phone infrastructure.

    In turn, this lowers the overall implementation cost. This means that upgrading to new hardware is unnecessary. In addition to the advanced telecommunications services offered by VoIP, you can maintain using your current phone hardware and phone number.

    Protocol for the First Session (SIP)

    SIP trunks are digital conduits for voice traffic. They allow companies to keep using their present phone equipment while taking advantage of VoIP. This adaptability of SIP trunks makes them ideal for cloud computing and PBX phone systems.

    As a result, people have more options regarding how they communicate. By sending speech and video data via existing Internet infrastructure, they may use already installed infrastructure and save money. SIP trunks can replace analogue phone networks since all communication data must pass through a network. Alternatively, a VoIP gateway can connect your phone infrastructure to SIP trunking.

    The price of launching a VoIP service is lowered as a result. Because traditional infrastructure like phones and modems is unnecessary, another selling point for SIP trunks is that they are offered on a pay-as-you-go basis, which is ideal for small businesses. Because you only have to pay for the time you use, you may save a tonne of money on your company's communications.

    IP-PBX Hosted (PBX)

    The hosted IP PBX is one VoIP that has seen significant adoption. Private branch exchanges are hosted and managed by the vendor. Because of this, they can provide unified communications options to businesses and consumers. Connecting to the cloud-based PBX network over the provider's IP network grants access to the VoIP service.

    The vendor handles off-site maintenance of all communication devices. The manufacturer handles everything from updates and patches to safety measures regarding software and hardware. In doing so, companies avoid the expense and hassle of installing and maintaining their phone systems. Also, it lessens the amount spent on both training and upkeep.

    Companies offering hosted IP PBX, such as 8x8, usually give customers a straightforward interface to manage their system. Here, they can keep tabs on and control their various telephony setups. Auto attendants, call queuing, on-hold music or messaging, and many other valuable extras are standard fare for the panel.

    VoIP Phone System Management over IP

    There are many parallels between this VoIP technology and hosted IP PBX. With a unified communications setup, an external service provider handles the management and upkeep. Yet, the company handles the phone equipment itself. The PBX service provider charges a regular monthly cost for setting up, configuring, and maintaining the system's telephone lines. A necessary hardware upgrade to support VoIP communication is also included in the price.

    Your company can find the best VoIP service after considering the options carefully. Compared to traditional on-premises VoIP systems, managed IP PBX is the better option for businesses that either don't want to or need help to acquire and maintain their own. Some businesses seek better methods of managing their internal and external communications. SIP trunks are suitable if the business has the resources to set up and maintain the technology internally.

    Hosted IP PBX systems on the cloud are the best VoIP solution for small and medium businesses. With this VoIP service, you won't have to worry about the high price and time commitment of managing VoIP equipment and calls on your own. You should be fine if you pick the proper hardware and software. Then, your carrier can deal with the headache of setting up and maintaining the underlying VoIP technology.

    Benefits of Voice over IP Systems


    More money can be saved because of this technique. This is because there is just one provider, meaning that only one network carries both voice and data. Free international phone calls can be made from any computer to any other with a high-speed Internet connection (such as DSL or cable). A PC-to-phone connection will typically cost you money, but it will be far less than your monthly phone bill.

    The low initial investment is the first advantage of VoIP when weighed against its drawbacks. Data was quite costly early in the development of internet connections, but as its use spread, its price fell dramatically. After the infrastructure is in place, calls between different VoIP installations do not cost anything. VoIP-to-landline calls may be more expensive than regular landline calls but still cheaper than regular landline calls.

    Also, unlike a regular phone, you won't have to pay extra for a line because the VoIP system would use your existing internet connection. You will only receive one bill if you have more than one internet subscription.

    According to some estimates, potential savings from switching from a landline or PBX system can be as high as 55 per cent.


    VoIP allows you a wide range of customization options. Your connection speed solely constraints call duration and frequency. A company's entire staff can be linked through a streamlined internal phone network, and the system can accommodate many additional phones with little effort.

    To maintain financial sustainability, agility, and growth, organisations that regularly deal with the public, such as call centres, must be able to adapt to changing circumstances.

    This adaptability persists even if you consider rearranging your office or adding to your staff physically. Cloud-based VoIP systems enable workers to do business from anywhere with an internet connection, opening up new possibilities for telecommuting, hot-desking and working from home.

    The effectiveness of the performance

    You can ensure top-notch sound and connectivity so far as your internet access is stable and the bandwidth is sufficient. It should be at par with, if not superior to, the standard telephone service.

    Long-distance calls no longer have to sound muffled or crackly because VoIP calls are unaffected by the distance between callers. You may make and take several calls simultaneously without sacrificing quality using VoIP.

    Using the same number no matter where you are can provide clients with the necessary continuity and reassurance. Knowing that you can reach people when needed, regardless of location or the availability of local telephone lines, can only assist your productivity. You may keep the same phone number even if your company moves across town or the globe.


    VoIP's accessibility is a significant selling point, and it's previously been established that it improves call quality. You are now allowed to areas where phone service is available. As long as both parties in a VoIP call have access to the internet, distance and location will not affect the quality of the call or the price at which it is made.

    When adding more extensions, there is no need to deal with the hassle of adding new copper wire or a new landline phone system. For the VoIP system to communicate with your company, only one Ethernet cable is required.

    A VoIP call can be initiated by logging into the user's broadband account and entering the desired number. When you're on the road or working remotely, it's convenient that you don't need a landline to make and receive calls.

    Improved performance

    Upselling additional features to clients who are looking for a higher quality voice calling experience is the foundation of many telephony business strategies, both classic and modern. The cost of staying connected might quickly skyrocket if this keeps up. Teleconferencing, call forwarding, caller ID services, call waiting, and even three-way calling are all valuable features that can help organisations of all sizes. Still, they typically come at an additional cost.

    In addition to the base rate and call provision, VoIP also offers many additional features. Don't feel like you have to throw in the kitchen sink right away. You can start with the basics and build from there as your needs evolve.

    This system's scalability makes it an excellent investment for businesses with ambitious expansion plans. Users can simultaneously exchange and receive data like papers and photographs, streamlining the remote collaboration process.

    Due to the increased prevalence of remote and homework caused by the coronavirus, global communication tools will continue to be critical for the foreseeable future.

    Problems with VoIP

    The flip side to every benefit is also a drawback. Even VoIP phone calls are subject to this policy. The disadvantages of VoIP service, which you should be aware of, are as follows.

    • Needs Access to Dependable Online Networking
    • Jitter and Lag
    • During an emergency, your location will not be recorded.

    Reliable Internet Connection Needed

    To begin with, the quality of your VoIP service is directly related to your internet connection. Having limited network bandwidth will undoubtedly impact the quality of service provided.

    It's a common misconception that VoIP consumes a lot of bandwidth, but that's not the case. Having a low-latency network is crucial for voice-over IP devices. The upload speed of each device must be at least 100 kbps. Ping and jitter, two delay and connection reliability indicators, should be below 70ms for a healthy connection.

    Your company's bandwidth requirements will rise directly to your anticipated number of active calls at once. Testing your present network's bandwidth is the best method to find out.

    Jitter and Lag

    Latency and jitter are two additional connection concerns that can affect the performance of any internet-based device.

    Data packets are the building blocks of all forms of digital communication, from email to video and audio. The original message is recreated by reassembling these packets at their final destination.

    There is latency and jitter when interruptions in transmitting these data packets or when they are incorrectly reassembled. The problem may lie outside your network entirely, as big ISPs frequently alter data pathways to ensure traffic is always sent via the quickest and most efficient means possible. There's really no special effort required to implement these modifications.

    What Causes Lag and Jitter

    • Limited bandwidth: As voice-over IP calls consume more data than conventional web browsing. Hence, if you are dissatisfied with your Internet speed, now may be a perfect moment to discuss the issue openly with your Internet service provider.
    • Poor router performance: A dedicated VoIP router is required for optimal VoIP service performance. Packet prioritisation enables the router to prioritise speech traffic over data.
    • Weak or insufficient cables: There are different types of Ethernet cables available, each with a different maximum transfer rate. VoIP calls require an Ethernet cable with a minimum performance of Cat-5e. Lower cables can't handle the required data rates.

    How to Resolve Latency and Jitter

    • Allow jitter buffering to take place
    • Go for a service that offers fast download speeds — Find out more about your bandwidth choices by contacting your internet service provider.
    • Ethernet cable upgrades Should be made so that all VoIP equipment is connected with a CAT-5e or CAT-6 cable.

    Emergency Call Location Tracking Limited

    As a last disadvantage, VoIP can be used to track your whereabouts. Due to VoIP's mobile and convenient nature, it is impossible for outside parties to determine the precise location from where a call is being made.

    There is no way to trace the calls back to a physical location or mobile tower because they originate from an IP address. Since ninety-nine per cent of callers don't require this data, it presents a problem for emergency services hotlines. During an emergency, you must let others know where you are.


    Voice over Internet Protocol (VoIP) is a method of communicating by phone that uses the internet instead of a conventional landline or cellular network. It's more common than landlines since it's cheaper, more adaptable, and offers more features and benefits. The freedom to make international calls regardless of the quality of the local phone network or signal is the most notable advantage. Even while VoIP does have a few limitations, the system's many benefits should outweigh them. The major focus of most VoIP hubs is the conversion of phone calls into digital data packets and their transmission over the internet. Broadband telephony, broadband internet telephony, internet protocol telephony, and IP telephony are just a few of the many names for this type of technology.

    With integrated access, businesses may take use of cutting-edge communication tools without having to invest in an expensive phone system upgrade. SIP trunks are appropriate for cloud computing and PBX phone systems because they are digital conduits for voice communication. Since all data in communication must eventually go through a network, digital networks can be used instead of analogue ones. In addition, they are available on a pay-as-you-go basis, making them accessible even to the tiniest of enterprises. The hosted IP PBX VoIP service is one of the most widely used VoIP solutions since it gives companies and individuals access to unified communication tools.

    Managed IP PBX services are similar to hosted IP PBX in that an outside provider manages and maintains the system, but in managed IP PBX, the business itself is responsible for the phones. Businesses can save money on internal and external communication costs by using VoIP. Cloud-based hosted IP PBX systems are the most advantageous for enterprises of any size. Since that there is only one service provider, only one data and voice network is available. VoIP to landline connections may be more expensive than normal landline calls, however, international calls made from one computer to another over a high-speed Internet connection are free.

    There is a lot of leeway for personalisation with VoIP, and it can save you up to 55% if you're currently using a landline or PBX. Financial viability, operational nimbleness, and continued expansion all depend on an organization's capacity to respond to shifting conditions. Telecommuting, hot-desking, and working from home are just some of the new options made possible by cloud-based VoIP systems, which allow employees to do business from anywhere with an internet connection. A major selling point of VoIP is its convenience; as long as both parties in a VoIP connection have access to the internet, distance and location will not affect the quality of the call or the price at which it is made. Several telephony business methods are based on upselling additional features to customers who are interested in improving the quality of their voice calls.

    VoIP is a great buy for growing companies since it streamlines remote collaboration by letting workers send and receive files like documents and photos in real-time. Yet, VoIP has its downsides, including a potentially unreliable internet connection, latency and jitter, delays in the transmission of data packets, and wrongly reassembled data packets. Assessing the current network's upload speed and bandwidth is the first step towards fixing these problems. Limited bandwidth, bad router performance, weak or insufficient cables, poor Ethernet cable performance, and poor emergency call location tracking can all contribute to the delays and pauses that users experience while using voice-over IP. Using a dedicated VoIP router with Cat-5e or CAT-6 performance, enabling jitter buffering, and choosing a provider with fast download speeds can help eliminate latency and jitter.

    Because of the portable and handy nature of VoIP, it is difficult for third parties to pinpoint the location from where an emergency call is being made. However, 98% of callers do not need this information, which is problematic for emergency services hotlines.
