Voice Over IP, also known as Voice Over IP, is a telecommunications technology that allows communication calls to be made over the network. Voice conversations are transmitted as a collection of data packets in this field.

VOIP has changed the fabric of telecommunications as it is practically replacing TDM-backed phones, while at the same time providing great benefits for local and business consumers.

People often start using VOIP to restrict communication costs.

Voice Over IP includes mobility, unified messaging, or presence-related communication functionality.

Not forgetting that VOIP has immense benefits including high mobility and presence-related communication possibilities.

The problem arises how IPv6 is better than the existing IPv4

The obvious reason to switch to IPv6 is that IPv4 is running out of addresses

The other benefit of IPv6 is that with IPv6 each machine can be assigned a specific IP address.

Quality of service

However, because VOIP uses IPv4, it has various quality issues like latency, jitter, and reverb, etc. The reason is clear; IPv4 has no internal QoS. That is why the moment there is a packet failure or outage due to overcrowding in the system, there is a degradation in quality.

By comparison, Internet Protocol version 6 addresses these issues by establishing a set of requirements to provide performance guarantees while traffic is transporting.

IPv6 classifies and marks IP packets to ensure a proven VOIP infrastructure. With the help of this technique, the network can indicate packets or traffic flows and then assign certain parameters within the packet headers to group them together. To implement QoS classification, IPv6 provides a traffic class field (8 bits) in the Internet Protocol version 6 header.

P2P and voice over IP

Skype, for example, which is one of the favorite VOIP services, uses P2P technology. Peer-to-peer is a model in which each party has similar capabilities and either party can initiate a communication call.

With Internet Protocol version 6, service providers like Skype can boast better quality conversations.

Voice over IP in IPv6 and free international calls

With improved QoS in IPv6, telcos have started to shift their focus to bringing larger progressive services to the world. What may have been difficult to achieve from a technical perspective until now and did not seem like an efficient business model has changed.

TrueFreecalls is one of those products, which although amateur in its form, provides what seems like the incoming revolution in VOIP. They provide free international calls to individual destinations everywhere. The user initiates a call to a local contact through which he initiates the global call, so he is only charged for making a local phone call.

This only seems to be the beginning, as the implementation of IPv6 continues globally, we can wait for more and more services to appear.
