VoIP became widespread in the 1990s and is now a staple in every company's communication stack.

Most brands choose VoIP for its flexibility in scaling global communications. In 2023, the US VoIP industry was worth $17 billion. What is VoIP, and how can businesses use it?

VoIP phone systems, their operation, and their benefits will be explained in this article. We will also compare voice over Internet phones to landline phones and discuss their main features.

This tutorial covers VoIP phone systems, whether you're moving or just curious about this cutting-edge technology.

VoIP?

VoIP lets you make calls over the Internet instead of landlines. This breakthrough has changed human interactions by enabling fast global communication. VoIP phones are increasingly popular among businesses and customers due to their low cost and versatility.

VoIP works how?

VoIP works like emails and other data transmissions. VoIP uses codecs to turn speech into data packets for IP networks. VoIP packets can be sent over LANs or other VoIP networks. Many varieties of VoIP allow you to handle an infinite number of calls to your company phone line without local phone service.

IPT is another VoIP kind that works similarly. IPT encompasses internet telephony and VoIP.

IPT can send voice, fax, and other communications across IP packet-switched networks.

Internet telephony uses the public internet for transmission.

VoIP is another type of IPT that uses private, controlled IP-based networks for transmission.

Voice over IP calls: how?

A VoIP call can be made with a few simple steps. VoIP calling works:

  1. Users call numbers using routers.
  2. Routers forward calls to VoIP phone service servers via the internet.
  3. This call uses the recipient's network and internet.
  4. Connect the call to the recipient's IP phone or device.

The Internet Phone: How Does It Work?

VoIP phone service providers have numerous helpful applications for small and large enterprises. VoIP's Session Initiation Protocol (SIP) compatibility is welcome.

As for VoIP phones or internet phones, envision a circuit switch that connects two lines directly but uses data continuously. Packet-switching can transmit call data across any path, unlike circuit switching. Speech generates data, but silence does not, unlike the PSTN.

How Are VoIP and Landline Phones Different?

VoIP phones or internet phones have advantages over landlines. Voice-over-IP uses the internet, unlike landlines. It allows multiple devices to use your phone line, unlike a landline.

Since VoIP calls are routed through the internet rather than the PSTN, they are safer. This lowers eavesdropping and delays for Wi-Fi and mobile data calls.

Cost of VoIP?

Service provider selection will depend on cost. Besides price, VoIP providers' reputation, features, customer service, and more should be considered. See how much VoIP will cost your business below.

Cost of One Setup

A PSTN phone connects your system to outside phone companies via copper wires. VoIP should require little or no installation since it uses internet infrastructure. A one-time account activation cost applies.

CPC per customer

VoIP lines cost $20–$30 per month per user. Business phone systems typically include toll-free minutes, call forwarding, caller ID, call waiting, call recording, and individual caller ID. PBX providers usually provide year and monthly billing periods.

Price Rises

VoIP setup and per-user charges are biggest. However, additional charges may arise:

No-cost phone time:

Your bundle may limit toll-free minutes. Exceeding the limit will cost.

VoIP hardware: Your VoIP phone system may need a new phone or analog phone converter.

Switch to a better VoIP plan if yours doesn't work. It will cost more, though.

Subscription VoIP phone service pricing

The number of telephone "extensions" determines the price of a VoIP phone system. Each phone costs one-time and monthly for installation, configuration, and maintenance.

The price also depends on the number of external lines (or “call paths”). In a company with 10 internal extensions, only five may need to make external calls. You can get by with five phone lines. To port your phone numbers to VoIP, you'll pay a one-time fee.

Compare VoIP and Landline Prices to Find the Best for Your Business

Enterprises should use VoIP for international calls. Many firms use group and conference calls for communication and collaboration.

Consider a landline if your company's internet is intermittent or slow. It also helps VoIP systems survive power interruptions.

Your organization needs to examine the benefits and cons of both options to find the best fit. Cost is also essential. VoIP is cheaper than landlines because of the high cost of installation and maintenance. VoIP installation costs less than $400, compared to $3,000 for landlines.

Savings from VoIP Switching

The savings a company can expect after deploying a VoIP system depend on its size and previous system. The savings are projected at 30–50%.

A survey indicated that up to 85% of organizations who converted from on-premise to cloud-based phone systems saved the most.

What VoIP gear do I need? Essential VoIP Tools and Parts

VoIP requires less gear than a phone line setup, but you'll still need the fundamentals and maybe some extras for functionality and convenience.

Modem/router input

VoIP requires a modem and router. Modem and router operate together to connect devices over IP.

A modem is needed to connect to an ISP. Wireless modems convert digital data into an analog signal that can travel across a telephone line or radio frequency. VoIP gear requires phone line infrastructure, which is ironic.

However, the router routes data packets to enhance network node communication. This device tracks recipients by IP address.

Optional VoIP Tools

VoIP simply requires a modem and router, but a few other pieces of VoIP phone equipment can increase call quality and convenience.

The VoIP Gateway

Analog phone signals can be transformed to VoIP data packets using a gateway. It can handle dozens or hundreds of calls at once, so you can use your phone system's infrastructure with VoIP.

It also allows PSTN, the century-old landline telephone infrastructure, to communicate more readily with the internet.

A VoIP gateway lets you make calls from your computer and exploit VoIP's mobility.

VoIP gateways' main benefit is the potential to build a larger network than with standard VoIP or landlines.

A VoIP gateway is not required for VoIP systems, but it can assist large teams save money when transitioning from legacy phone systems to VoIP.

Desktop VoIP Phones

The traditional look of a VoIP desktop phone can help newcomers feel at ease. They also learn how to use its advanced features, such as a caller ID display, speed dialing, and hold, transfer, and conference call buttons. Some gadgets have headset, microphone, wireless headset adapter, camera, and other ports.

Wireless VoIP Headsets

Headphones and microphones in VoIP headsets free your hands during discussions. VoIP headsets are wireless headphones that connect to a computer or device, removing the need for a desktop VoIP phone. Noise cancellation may improve call quality on the headset.

VoIP headsets or desktop phones may be chosen. Both settings may increase worker VoIP quality and usability.

If your firm only needs VoIP, a modem, router, and (if needed) VoIP gateway are plenty.
