VoIP is a short form of Voice over Internet Protocol and is also known as internet telephony, IP telephony, voip ip phone, voice over ip, phone over ip, voip phone, voice over ip phone, voip telephone, voice ip phone, voice over ip telephone, voip phone system, ip phone systems, voip telephone systems, voice over ip phone system, or Internet calling. It is considered a great alternative to the PSTN or public switched telephone network. VoIP transfers voice over the internet instead of using standard phone lines.
While it may seem a VoIP phone system is not very complicated. As technology advances, you will see increased use of cloud-based phone systems. Recent improvements and advancements in software and hardware make it a standard means of communication for businesses looking for a reliable way of communication.
VoIP provides an incredibly flexible solution that lets you make and receive calls without tying you to an office or desk phone. It means you can access your calls without any hassle and reduce the overhead charges for installation and hardware.
Basically, VoIP is a reliable, cost-effective, and flexible communication system that you must have for your business.
Before going further, you may want to know how it works.
Wherever you have an internet connection, you can use VoIP. By using the Internet, it compresses your voice into a digital file and then transfers it.
Small digital packets transfer all your conversations; the Internet can transfer these packets worldwide within seconds. VoIP is built upon Session Initial Protocol to provide interactiveness between all VoIP apps and desk phones. Its working process has divided into three steps, have a look!
A codec converts audio signals into digital packets. These can be hardware or software-based processes that compress your voice signal and convert them into digital signals.
The data packets are then transmitted through IP. It can be either done online or across a Local Area Network (LAN). This transmission is quick.
The data packets arrive at their destination. From where codecs will unpack the data and again convert it into audio or voice signals.
One best thing about VoIP systems is that they can work on the existing systems. The recipient also does not need any specialised device. Once all the packets are converted into voice signals, they will run through a standard phone line. You can get hardware that is compatible with Software for VoIP. VoIP phones are similar to standard desk phones that you may have used in the past, but they have more advanced features.

The VoIP phone system works a bit differently from PSTN. When your voice is transmitted through IP, it is not sent down to a phone line. Instead, it is converted into digital packets and transmitted via the internet.
It is a simple process of conversion of voice signal into a digital packet, transmission over IP, and unpacking. It works in the following way:
An internet connection can transfer data from one point to another in a specific period. It is usually measured at 1000 bits per second (Kbps). The higher the bandwidth of your connection, the more VoIP calls it can support. If you have a connection with lower bandwidth, the quality of VoIP calls will be affected.
Codecs can be software-based or hardware devices used in the VoIP process. They are used to convert voice into digital packets before transmission and compress these signals for transmission. Then they re-convert them into voice signals at the other end.
DSL is an acronym for 'Digital Subscriber Line'. It is a conventional phone technology that allows a broadband connection over current phone lines. It is used to transmit digital data over telephone lines. On the other hand, it still allows analogue phone signals to travel through the same copper lines.
The 'IP' stands for Internet Protocol, providing a set of rules on which data is transmitted and received online. These standard rules let devices communicate with each other even when running on different platforms. IP also provides general rules for data packet transmission. However, it does not order the packets being transmitted or establish any connection for doing so. It is handled by transmission protocols.
IVR stands for Interactive Voice Response, a feature of conventional telephony. It is an updated auto-attendant version, which allows callers to use menus and handles call transfer and forwarding. For example, 'press one for the sales department’ etc.
It refers to the time taken in the transmission of data. The more the latency, the greater the delay in the data transmission. High latency can affect the performance of VoIP, especially when you are using it for video conferencing. Voice quality is also affected, and voice delays are noticed with a latency of around 150 milliseconds. If latency is more than this value, the quality of call is compromised.
PBX is an acronym for Private Branch Exchange. It refers to a private telephone network used within an organisation. It allows you to press a button on your desk phone and reach another person in your office. On the other hand, hosted PBX is a provider responsible for housing PBX at their location. They also manage the required technology and maintain the phone system. In such a PBX, the phone lines are plugged into a router that sends calls, signals and features to the provider.
RTP stands for Real-Time Transport Protocol. It is an internet protocol that transmits VoIP call data packets. It also transmits audio and video streams to allow other forms of multimedia communication. In contrast, SRTP is a Secure Real-Time Transport Protocol, an encrypted and more secure upgrade of RTP.
It is also a way of transmitting voice communication over the internet. In many ways, it can act as an alternative to VoIP. Typically it works by connecting PBX to the internet. It provides added control to the user but needs more equipment compared to a VoIP phone system. SIP Trunking involves several phone lines. One SIP line can handle one call simultaneously, while SIP trunking can handle any number of SIP lines.
A traditional phone system depends on landlines. These phone systems use physical landlines connected to the phone socket and a receiver. Many businesses combine this with the PBX system, allowing them multiple phone lines. On the contrary, a VoIP phone system does not need any physical infrastructure like a traditional landline. With VoIP, you only need a reliable internet connection and use a softphone on your computer or any device like a smartphone. The best thing about a virtual phone system is that it has many advanced features that help you streamline your business communication.
It would be best if you had the following major equipment to use VoIP services. • Modem • Router You may find both of these in your existing Internet set up too. Users can even make calls by downloading their softphones on desktops, laptops, and smartphones.
