The Backbone of Communication: Exploring VoIP Network Infrastructure

The current state of communication is constantly evolving and transcending to new heights, and the reason is the emergence of Voice over Internet Protocol Network Infrastructure. The rise of the fabric of VoIP has enabled all to break through the boundaries of traditional telephony and unlock the true essence of modern communication.

While VoIP has emerged as the cornerstone of modern communication, revolutionizing the way we connect and communicate, it is important for us to understand the supporting pillar, i.e., its Infrastructure.

In this blog, we will discuss the ins and outs and delve deep into the intricate web of VoIP network infrastructure. But before we get to the technicalities, let’s first understand VoIP network infrastructure.

The Role of the Internet in VoIP

Overcoming the limitations of traditional phone infrastructure, VoIP has become the go-to solution for businesses and individuals alike looking for a solution that has a complete set of features and offerings. And accumulating to the evergrowing demand, VoIP is completely dependent on the Internet even to start taking its first baby steps, which makes it well-suited for the current communication landscape.

Understanding VoIP Network Infrastructure

Voice over Internet Protocol, or, plainly, VoIP Network Infrastructure, is a collection of many simpler technologies like connection, bandwidth, software, and hardware that work together to make it possible for voice communication or messages to be transmitted over the Internet.

The VoIP technology works by first converting your voice signals into digital data packets, which are then sent over the Internet to the right receiver. Then, in the end, at the receiving end, the digital data packets are converted back into voice signals, which the receiver responds to.

To digest this information easily in simpler terms, it is a technology that allows you to make and receive calls using the Internet. It is also known as IP telephony or Internet telephony.

If you are here, that means you want to implement a VoIP infrastructure for your business. Mark our words, it is not an easy task to accomplish. To begin with the implementation process, you should know every detail of the design and the architecture of the VoIP infrastructure.

Single Site vs. Multi-Site VoIP Networks

Being much easier to design and manage, Single Site networks cost way less than the later alternatives and are located in a single physical location. On the other hand, multi-site networks span over multiple locations and offer a number of advantages, such as the ability to extend VoIP services to remote offices and branches.

Cloud-Based vs. On-Premises VoIP Solutions

A cloud-based VoIP solution has its own set of abilities and is hosted and managed by a third-party provider while being easier to deploy and manage when compared to on-premises VoIP solutions. In contrast, an on-premises VoIP solution is a VoIP solution that is hosted and managed by the organization that uses it and can be more cost-effective in the long run.

Factors affecting the efficiency of VoIP Infrastructure

Having learned about the types of VoIP networks available. Let’s move on to the factors hindering the efficiency of the VoIP infrastructure that you want to implement.

Redundancy and High Availability

If you are looking to build a VoIP infrastructure yourself, the first thing you need to do is keep your focus on its redundancy and high availability. 

But what does this mean? This simply means the network should be available and continue to operate even if there is a failure of one or more components. To achieve this, there’s one common solution, and it is to use multiple VoIP servers and gateways, and the other one is to use a load balancer to distribute traffic across multiple servers.

Bandwidth Considerations

To pump up the efficiency of your VoIP infrastructure, you need to take a dive and consider what bandwidth is sufficient enough to operate productively. To make the decision easier, take factors such as the number of users on the network, the type of VoIP calls being made, and the codec that is being used into discussion. This simple step will help to ensure that the network has enough bandwidth to meet the needs of the users.  

Network Assessment and Planning

Before designing a VoIP network, it is important to assess the existing network infrastructure. This will help to identify any potential bottlenecks or limitations. Finally, after collecting the information about everything needed, you should start by building a well-structured plan to make the implementation procedure easier. 

Types of VoIP Protocols

Now that you understand what a VoIP network Infrastructure is, as well as its design and infrastructure. Let’s move on to the types of VoIP protocols.

SIP

Known as the most widely used VoIP protocol, Session Initiated Protocol (SIP) establishes, maintains, and terminates VoIP calls. The flow of VoIP traffic is controlled by SIP messages sent over the Internet. A VoIP protocol such as SIP can be used for implementing call forwarding, voicemail, and conference calling features.

H.323

Although it is an older protocol than SIP, H.323 still happens to be used in some notable network environments. Despite the fact H.323 being more complex, when compared to SIP, it comes out to be the better one, as it supports video conferencing and multicasting.

RTP and SRTP

Though both sound synonymous, Real-time Transport Protocol(RTP) and Secure Real-time Transport Protocol(SRTP) are two separate transport protocols and are used to deliver VoIP calls over the Internet. Additionally, RTPs and SRTPs are reliable protocols that ensure that voice data is delivered in real-time without any errors.

MGCP

Lastly, we have Media Gateway Control Protocol(MGCP), which are devices that convert VoIP signals to traditional phone signals and vice versa. It is also known as a protocol that is used to control media gateways in VoIP and traditional telephony.

Key Features of VoIP Network Infrastructure
