What is VoIP?

VoIP stands for voice over internet protocol. Also known as IP phone, Internet phone or internet call. It is an alternative to PSTN. Although it sounds good, VOIP phone system is not complicated.

At the simplest level, VoIP telephone system is a way to transmit voice calls through IP network. This is a way to make a call using an Internet connection, not a way to make a call using a landline. The latest progress and improvement soon make it the standard communication mode for enterprises that need reliable and future oriented communication mode. Modern top-level VoIP is now consistent and reliable.

VoIP represents a low-cost and barrier free telecommunications option for all types of companies. Adopting this type of telephone system can reduce or eliminate various costs related to traditional enterprise communication. Call costs are usually much lower, and companies don't have to pay for multiple lines or lots of hardware.

VoIP telephone system is your communication choice that can not be ignored. But before you go on, you'll want to know exactly how it all works.

Voip How It Works

How does VoIP telephone system work?

For regular calls, a service provider (usually a private phone company) provides a specific physical path. The path is between yourself and the call you made. The system also utilizes the traditional telephone infrastructure, which means a network of telephone lines across the country.

Using VoIP service, the call transmission mode is different. The audio (your voice) at the end of the call will be converted to digital packets. Just as traditional envelopes contain what you write, it's easiest to think of them as data envelopes.

The conversion of audio signal to digital data packet is processed by so-called "codec". The codec can be a hardware device or a software based process. They compress speech signals and then encode them into digital signals. To continue our analogy, they take what you say and put it in a digital envelope.

The packets are then transmitted over IP. This can be across a local area network (LAN) or online. They are usually transmitted through real-time transport protocol (RTP). Or, if not, through secure real time transport protocol (SRTP). The latter is only an encrypted version of the former. This stage of the process is like a postman picking up your envelope and taking it to your destination.

The packet reaches its destination almost immediately. Then they need to be decoded and decompressed. This is handled by the codec. They take digital data and convert it back to an audio signal. The receiver of your phone will hear you, just like through a normal telephone line. At the end of the transmission, the codec opens the envelope for reading.

In addition to technical aspects, the process of making VoIP calls is not much different from that of standard calls. To make a call, you can use a hardware or software based VOIP phone.

The former is very similar to a traditional desk phone or handset. It looks almost the same and can be used in all the same ways. It doesn't just mean making a phone call. Most VOIP phones also allow you to use voice mail, make internal calls, use call routing systems or auto assistants, and call forwarding tasks. Some even have screens for video conferencing. If no one tells you, you may not know that you are not using a traditional phone.

Software based VOIP phone is usually called "software phone". They are applications or programs installed on a mobile phone or computer. These applications or their interfaces replace traditional mobile phones. They are usually designed to look similar and can be used through a touch screen or keyboard. Calls through these phones usually use headphones and microphones. They can also use the computer's built-in microphone and speakers.

Advantages and disadvantages of VoIP

The advantages of VoIP include:

Lower cost. The price is lower than the typical phone bill.

Higher quality sound. For uncompressed data, the reverberation or blur of audio is small.

Access rights for remote workers. It's very suitable for teleworkers because they have many options to attend meetings or communicate with other teammates.

New features. These features include call logging, queuing, custom caller ID or voice mail to email.

International rates are low. When a landline makes an international call, it rents a wired circuit to transfer the call overseas. VoIP doesn't need a wired line, but uses the Internet to make calls, which means it's considered normal traffic and cheap.

Despite these advantages, VoIP services may still have some disadvantages. These disadvantages include:

Not all of these services can be directly connected to emergency services.

VoIP requires a high-speed Internet connection.

The service will not work properly during the blackout.

Depending on the VoIP service, the directory service may be missing.
