Understanding VoIP Phone Systems

A VoIP Phone is a kind of telephone that uses IP technology to transmit calls. It can come either in the form of specialized digital hardware or a program (running on a computer or mobile device) that performs the same functions. With its microphone and receiver, a VoIP telephone takes the sound you generate and converts it into packets of data, which it sends over the network and out through the internet. On the other end, the phone decompresses the data and plays it back for the other person to hear.

How Does VoIP Work?

A VoIP phone system is a technology to make phone calls through your internet connection instead of a regular landline or a mobile network. A VoIP system converts analog voice signals into digital signals over your broadband connection. A VoIP server is used to connect calls to other telephone networks.

As long as you have a high-speed internet connection, which includes a router and modem, you are ready to use a VoIP.

A typical VoIP configuration involves a desk phone and a SIP server, which is typically a VoIP service provider. It works even better than your traditional landline phone because it offers many more features than what analog phone service could ever provide. Since VoIP runs over the internet, your data is stored securely in the cloud. You can manage the VoIP system through an online dashboard. This dashboard allows users to adjust contacts, business phone numbers, call forwarding, and add new phone numbers.

Equipment You May Need in order to use VoIP

VoIP phone systems (PBX)

A VoIP PBX (Private Branch Exchange) is a business telephone system that facilitates phone calls over the company’s LAN or WAN data network rather than through the circuit-switched networks.

VoIP PBX is available in two deployment options – on-premises and cloud-based. With an on-premises voice solution, the hardware is installed and runs on-site at your office or data center while a cloud PBX system is delivered entirely over the Internet and managed completely off-site by a service provider.

VoIP phones or IP phones

VoIP phones, or IP phones, are the physical office phones that you can use with a VoIP phone system. Visually, they do not differ much from the traditional, stationary phones you find at your home or on your work desk. Because of this, it’s quite easy for employees to adjust to newer VoIP phones. The one fundamental difference is that they are internet-enabled, whether via WiFi or Ethernet. They are assigned IP addresses to facilitate calls over your network.

Mobile phones, computers, network-ready devices

In addition to IP phones, you can also access VoIP phone systems using your own mobile device, computer, and other network-ready devices with VoIP apps or softphone application installed. Today you can make and receive business phone calls anytime, anywhere using your own Internet-connected devices, without worrying about losing VoIP call quality. Employees are no longer tied to a desk phone and may use any device of their choice.

VoIP gateways

A VoIP gateway is a hardware device that converts traditional telephony traffic (analog or digital) into packets of data, allowing connections between legacy telephony infrastructure and IP-based communications, acting as a bridge between an IP network, the PSTN (Public Switched Telephone Network), and the cellular network.

Benefits of IP Telephony

1. Cost Savings

Cost savings, mobility and scalability, are cited as some of the key advantages of switching to IP Telephony. 

2. Easy to Install

Comparing to traditional phone systems, the installation and configuration of VoIP systems could be super easy. Traditionally, with a landline system, office phones require physical lines to receive phone service. VoIP phone systems eliminate the need to install any physical phone lines. All you need to do is to connect IP phones to the corporate network via Ethernet lines.

Better yet, if you need your IT staff to prioritize more important and revenue-generating projects instead of managing the phone system, hosted phone services leave the work to the service provider and there is no need to worry about any network issues. It would be beneficial for small businesses and start-ups lacking in technical expertise or resources, too.

3. Mobility & Geographical Flexibility

With a rise in remote working, hotdesking and co-working and hybrid setups, the use of IP Telephony significantly improves your ability to be agile, allowing your teams to set up their phone service from anywhere. 

4. Scalability

Using IP Telephony over analogue telephony means you don’t have to pay separately to add new phone lines. Having a landline service means each line is payable, whereas with IP Telephony Services, there are far fewer restrictions and lines can be added quickly and easily, allowing you to scale up or down. 

5. Abundance of Features

VoIP services deliver a number of features that are either not supported by traditional telephone systems or only available for an additional fee. These features are more than ‘extras’. Many businesses have found it easy to use VoIP and became more competitive with the full suite of built-in features. Some features may help companies meet important safety and security needs, including the ability to connect with emergency services while using internet VoIP.
