    People who use VoIP can make phone calls using a high-speed Internet connection rather than a traditional phone line. Some VoIP providers may only allow you to call other persons using that specific service. At the same time, others may let you contact anyone with a phone number, regardless of where they are located. Not all VoIP services require a computer or dedicated VoIP phone; some even let you use a regular landline with a VoIP adaptor.

    The technology behind VoIP phones combines hardware and software that allows users to make and receive calls via the internet.

    Internet protocol (IP) networks are used to make and receive phone calls instead of the ageing PSTN and ISDN systems of traditional telephone service (ISDN).

    Since VoIP technology requires less physical infrastructure to deliver phone calls, it is far more cost-effective to supply these services.

    This is because Voice over Internet Protocol (VoIP) services also provide your phone system via the internet. Formerly pricey tools and services are now within reach for small and medium-sized enterprises. These features include call recording, instant messaging, international calling, music on hold, and call forwarding.

    FAQs About VoIP

    Again, it depends on your setup. VoIP calling app-to-app is almost always free; calling a landline or mobile number may cost a little; and other VoIP services, including those from Hyperoptic or business providers, require a monthly fee.

    VoIP: Advantages
    • Lower costs.
    • Increased accessibility.
    • Complete portability.
    • Higher scalability.
    • Advanced features for small and large teams.
    • Clearer voice quality.
    • Supports multitasking.
    • More flexibility with softphones.

    VoIP or Voice over Internet Protocol takes analogue voice signals, converting them into digital signals, then sending them as data via your broadband. It is a fast and flexible telephony solution and in fact, you can use a normal phone with VoIP.

    How does VoIP work on cell phones. You can complete VoIP calls or texts through a service provider's VoIP app for your iPhone or Android device. When you place calls with your cell phone over VoIP, your voice data gets converted into digital signals.

    For a VoIP phone system to work, you have to have a modem and router, which are part of your existing internet setup. Users make calls from any device that has your call software downloaded. This device can be a smartphone, laptop, or desktop.

    VoIP Phones Work

    what is voip and how does it work (2)

    Telephones were previously connected to a Private Branch Exchange on the premises (PBX). With this cumbersome device, all calls would be routed correctly. A PBX phone system can't compare to the features of a VoIP phone.

    Using packet-switched protocols, VoIP technology transfers regular phone calls to and from the internet. Packet-switched voice-over-internet protocol encapsulates phone calls in small data packages. Virtual Private Network (VoIP) packets can go over a LAN or any other VoIP-compatible (LAN) network.

    VoIP phones utilise existing computer network cables or Wi-Fi to connect to telephone networks; this is possible since VoIP calls are processed in the cloud or online.

    While using a VoIP service for business, you won't need to install any new copper cabling. Keeping your current phone number saves you the trouble and money of re-registering it.

    With this in mind, utilising VoIP to make a phone call is a breeze. To make a call, seize the phone and dial the desired number. It shouldn't be challenging, and that's precisely what the technology is meant to do.

    Do Voip Phones Work Like Real Phones?

    Yes. A VoIP phone has the same capabilities as a traditional phone line or mobile device. The bare minimum is a regular phone in your hand. Traditional phone services can still be used alongside VoIP.

    A call can be made or received using this. Rather than using traditional copper phone lines, your voice will be sent over an internet connection. Access to the internet is the sole prerequisite.

    For example, you can use this feature of specific voice-over IP services to forward your landline calls onto your cell phone. Hence, you can make and receive landline calls without touching your handset.

    To What Extent Will I Need Special Tools?

    Access to high-speed Internet (broadband) is essential. In addition to dial-up and other slow connections, cable modems and other high-speed services like DSL and LANs are also viable options. Technology such as a computer, adapter, or dedicated mobile phone is needed. While some VoIP services require you to utilise a computer or a dedicated VoIP phone, others let you use a computer or a VoIP phone in conjunction with a VoIP adaptor. Your computer, some software, and a cheap microphone are all you need to get started. VoIP phones connect straight to your internet and function like a regular landline. Dialling is the same as it always has been with a VoIP adapter-enabled phone; some providers even offer a dial tone.

    Do Long-Distance Calls Differ from Local Calls?

    Some VoIP providers offer entirely free service; however, this is typically limited to calls between users of the same service. If you use a VoIP service, you can choose a different area code from your residence. This also means your callers may be subject to long-distance fees depending on their area code and provider.

    Similarly to the rates of traditional landline telephone service, some VoIP companies impose fees on calls made to numbers outside of the local calling region. While using other VoIP companies, you can make international calls for a set price per minute.

    Who Can I Contact Using VoIP Service?

    You may only be capable of calling other service users, or you could call any number with a telephone service, no matter where it is located worldwide. A standard analogue phone is required to converse with someone who has received your call. You can hold group conversations with the right VoIP provider.

    Comparisons and Contrasts VoIP and Traditional Telephones

    You can see from this comparison that VoIP and traditional landline phones are fundamentally different in terms of their connection to and use of the telephone network and the management of incoming and outgoing conversations. Here is a quick review of the key distinctions:

    • VoIP phones must be registered online with a service provider to use the phone network. In contrast to VoIP phones, traditional office phones require copper wire and an Ethernet connection.
    • Virtual private network (VPN) phones are associated with user accounts rather than phone numbers. A VoIP phone's "toggle buttons" let you quickly move between the multiple active calls on the same account.
    • The high-definition voice on VoIP phones is twice as loud as that of a standard landline call.
    • Due to Power over Ethernet (PoE), certain VoIP phones can be powered directly from a PoE switch, eliminating the need for an additional power supply.

    Yet, VoIP phones share many features with traditional desk phones.

    • VoIP phones have a standard phone keypad.
    • VoIP phones, like traditional office telephones, typically contain individual buttons for commonly used functions like call holding, transferring calls, and viewing caller ID.
    • VoIP phones look and feel the same as any other office phone.
    • VoIP and landlines are structurally identical regarding how handsets, receivers, speakers, and other components are set up and used.

    But, if you are familiar with using a traditional office phone, you will have no trouble learning to use a VoIP phone. Using VoIP phones does not necessitate a radical change in how you now handle incoming and outgoing calls.

    What are the Benefits of Moving to VoIP?

    A business might save money by switching to VoIP from its traditional landline service. Still, three, in particular, stand out for enterprises with large contact centres, numerous office employees, or rising long-distance expenditures.

    • Long-distance fees are eliminated with VoIP because calls are made and received through the internet, which is already being paid for by most people. Distance does not affect the cost of calls between two locations on the same network provided by the same service provider. Compared to more traditional phone services, VoIP is often more cost-effective when making calls across networks or to landlines.
    • VoIP improves productivity by connecting voice calls to tools like unified messaging, cloud-based collaboration, and business intelligence software.
    • The scalability of cloud phone systems is superior to that of traditional phone systems, which necessitate the installation of hardware on-site to support an organisation's growing user base. When a company needs to expand, VoIP can be expanded quickly and cheaply to accommodate the expansion.

    Why VoIP for Business?

    Businesses with substantial phone service costs need help maintaining their ageing telephone equipment or are undergoing a process transformation to take advantage of new technologies that stand to gain the most from implementing VoIP. These are just a few of the arguments that favour VoIP for businesses.

    • Reduced financial outlay: There is a risk that national and international organisations would need help with the financial load of long-distance and international calls. With VoIP, you won't have to pay extra to make long-distance phone calls like you would with a regular phone company.
    • Link up different workplaces: Traditional phone service can be a logistical nightmare for a company with offices in multiple locations across the country or even the world. With VoIP, a company may connect all its locations' phone lines into a unified network.
    • High-speed, broadband online access: Most businesses already have the necessary internet infrastructure and capacity to implement VoIP. VoIP often does not necessitate significant upgrades, but call centres may require more bandwidth to a location.
    • Don't waste money on old phones: To expand the capacity of a traditional landline phone service, investing in costly maintenance of on-premises equipment and equipment upgrades is necessary. VoIP doesn't require new wiring because it runs over the building's existing Wi-Fi network.
    • Technology must be scalable: The scalability of an organisation's current IT infrastructure may be tested by a sudden increase in workforce size. VoIP can grow as fast as more computers, smartphones, and landlines are bought and set up.
    • Conquering Physical ObstaclesIntegration of teams from different nations is a unique difficulty for global organisations. VoIP can significantly simplify communication across great distances when combined with other tools for managing distributed teams.
    • Interoperable or unified communications: Modern contact centres and internal communications can benefit from VoIP since it paves the way for cloud-based collaboration and unified communication platforms. Traditional telephones limit the possibilities of unified platforms due to the importance of voice calling.
    • Business-grade Voice over Internet Protocol (VoIP) management: For a flat monthly rate per user, managed service providers like Epik provide all the necessary gear and software. Companies who wish to avoid the high cost of acquiring and maintaining their own VoIP hardware can make the changeover less hassle using a hosted VoIP service.

    Difficulties and Limitations of Voice over IP Systems

    what is voip and how does it work

    One of the main disadvantages of switching to VoIP from a conventional phone system is the reliance on internet technologies to transmit voice calls. Internet and bandwidth constraints are the most typical source of trouble with VoIP quality.

    VoIP has a few drawbacks, such as higher electrical bills or more troublesome connections due to slow or unstable internet service. The potential drawbacks of using a VoIP service are discussed below.

    Sound Quality During Calls

     Problems with VoIP quality include longer-than-usual wait times to place calls, unusual or repeated tones, and background noise that needs to be present when using a traditional landline. These problems can arise for several reasons, including but not limited to an inadequate internet connection, insufficient bandwidth, faulty VoIP equipment, or an unreliable VoIP service provider.

    Although many VoIP providers have been working to improve their service, quality problems might persist when using a slow or unreliable internet connection. Organisations gain valuable time and resources fixing VoIP issues with a managed VoIP solution.

    A Power Source Is Required

    The telephone company provides the electricity to run a standard telephone via a landline. Landline electricity means they can keep running even if the grid goes down in your area. However, because VoIP gadgets draw electricity from the wall, they may only function during blackouts if backup generators are also running. In addition to driving higher power use, this can increase an organisation's monthly utility costs.

    Internet Bandwidth

    VoIP utilises a high-speed internet connection; therefore, it will increase data usage. To support the data needs of a new VoIP service, it may be necessary for large enterprises to upgrade their bandwidth. Security

    The security risk of transmitting data via a public network is another limitation of technologies like VoIP. Organisations worried about privacy breaches should carefully evaluate security measures when adopting a VoIP service, even though many VoIP telephones and hosted services are built to encrypt voice data before sending it over the internet.

    Dialling 911 for Emergencies

    Because 911 is already built into the standard phone network, VoIP providers have not been mandated to provide access to the emergency number. The VoIP sector has responded to the necessity for 911 service by providing it to its consumers, particularly residential ones.

    Maximising Your Voice-Over IP Experience

    A business can get the most out of VoIP in several ways. Some suggestions are as follows:

    VoIP Services That Are Hosted

    To facilitate the management of a location's VoIP service, today's hosted solutions rely on servers located in the cloud for communication. Adding or removing cloud servers or modifying server configurations is all it takes to adjust resources to accommodate a different user base. It also makes hardware failure recoveries quick and secure.

    High-speed Internet using Optical Fiber.

    Optical fibre internet services enable businesses to run networks that bridge geographically separated locations. The service provider monitors and fixes these private connections around the clock.

    A private fibre-optic network offers superior throughput and stability compared to public broadband Internet. With a private fibre-optic network, your VoIP data may safely and unobtrusively bypass public internet traffic.

    Reliability Assurances

    While selecting a hosted or managed internet access, finding a guaranteed uptime is essential. Some service providers can now offer uptime guarantees of 99.9% because of cloud computing and the ease with which they can switch to backup servers in case of an outage. If you use a service, go with one that guarantees its work.

    Effective Assistance

    The provider's availability of helpful customer care is also crucial for a successful VoIP service. If a service has a guaranteed response and resolution time and can reach them via various methods (email, phone, social media), consider using them.


    Calls made and received using VoIP phones are transmitted and received over the Internet rather than a standard phone line.

    Regular phone calls are routed through the internet using packet-switched protocols. VoIP services necessitate the use of a computer or a dedicated VoIP phone; however, some providers also allow the use of a standard landline with the addition of a VoIP adaptor.

    It is much cheaper to provide telephone services using VoIP technology because much less physical infrastructure is needed to do so. VoIP telephones use Internet Protocol (IP) data cables or wireless Internet to connect to the telephone network.

    Don't go through the hassle and expense of changing your phone number if you don't have to. An internet connection is all that's needed to make or receive calls on a VoIP phone, which otherwise functions just like a regular landline or mobile phone.

    Broadband Internet access is vital in today's world, necessitating the use of specialised hardware like a computer, adaptor, or mobile phone. In contrast to local calls, long-distance calls via a VoIP service may cost money, depending on the provider. 

    Your calling options may be limited to other service users or extended to include any number, anywhere in the globe, that has access to a telephone service. The correct VoIP service will allow you to have group chats.

    VoIP and landlines are fundamentally different in how they connect to and use the telephone network and how they handle incoming and outgoing calls. Whereas traditional office phones necessitate copper cable and an Ethernet connection, VoIP phones can connect to the network simply by being registered online with a service provider.

    VoIP phones, on the other hand, have a lot in common with regular desk phones. Both types of phones offer high-definition sound, a normal phone keypad, and dedicated buttons for frequently used services like call holding, call transfer, and caller ID.

    Phones, receivers, and speakers in VoIP systems are set up and utilised in the same way they are in traditional landline systems.

    Companies that have huge contact centres, lots of office workers, or escalating long-distance expenses can especially benefit from transitioning to VoIP from traditional landline service. The use of VoIP for making calls across networks or to landlines is more cost-effective than using traditional long-distance calling methods.

    Connecting phone conversations with other tools like unified messaging, cloud-based collaboration, and business intelligence software increases efficiency. The scalability of cloud phone systems outshines that of traditional phone systems, allowing for easy and inexpensive expansion to keep up with business needs.

    It helps save money and bridges geographical gaps between offices. With VoIP, businesses can consolidate their phone lines into a single network, offer broadband Internet access to all of their employees, eliminate the need to replace ageing telephone equipment, save money, and scale. In addition, unified communications, cloud-based collaboration, and VoIP administration at an enterprise level are all made possible.

    Physical barriers, scalability issues, and high costs all contribute to VoIP's limited usefulness. There are a few negatives to VoIP, such as increased electricity costs or connections that are more difficult to maintain due to slow or inconsistent internet connectivity.

    There are a number of issues that can detract from the quality of a VoIP conversation, including longer than typical wait times, strange or repetitive tones, and ambient noise.

    Companies could think about implementing a managed VoIP solution with a power source and increased bandwidth to solve these problems. Hosted VoIP systems also allow for emergency calls to be made to the 911 service. Hosted systems of today rely on cloud-based servers for all communication, which allows for speedy and safe hardware failure recovery.

    Business networks that use optical fibre internet services can more efficiently connect otherwise distant sites than the public broadband Internet can. Guaranteed response and resolution times, along with excellent customer service and a focus on reliability, are all must-haves.
