The most commonly used VoIP protocols are TCP, SIP and H. VoIP can also use other protocols such as MGCP, SCCP, etc. The voice over Internet protocol, VoIP, has experienced an enormous level of growth in recent years and is likely to continue, or even increase, in the near future. The reason for this level of growth in the use of VoIP is due to the cost savings it provides, the increase in flexibility, and the fact that the same network can be used for voice and data.
Although the first VoIP networks began to appear as early as 1995, these VoIP networks used proprietary protocols to allow the exchange of IP data. However, with rapid growth and the need for VoIP traffic to be routed globally, there was a need to establish standards to control data exchange. In view of the fact that there were a number of different requirements, several standards were developed that are used today. Although it may be surprising at first sight that there are several VoIP protocols, these different protocols are necessary for different reasons and have been deployed in many systems.
Although the concept of a unified VoIP protocol or suite of protocols seems ideal, this is unlikely to happen in view of the extent to which the different protocols have already been implemented. In addition, different companies and organizations will use the VoIP protocol that best suits their requirements and, consequently, will want to maintain what they currently use. This will mean that there will be resistance to any changes, especially since the interfaces have been designed to allow interoperability. In addition to the organizations involved, there are also a variety of different VoIP protocols and standards.
One of the advantages of VoIP is that it does not legislate on the architecture of the network that transports the data. The first telecommunications networks used a centralized structure in which all information was contained in the switching station or central station. With the advent of packet technology, routing and intelligence can be distributed where it is most convenient to place them. This can be through a distributed or centralized architecture.
While both architectures can be used with VoIP, the type of architecture has an impact on the optimal VoIP protocols that should be used. This is one of the reasons why several VoIP protocols are used, and will continue to be used.

VoIP endpoints generally have to wait for the transmission of previous packets to complete before new data can be sent.
Hosted or cloud VoIP solutions involve a service provider or telecommunications operator hosting the telephone system as a software solution within its own infrastructure. Compromised VoIP session credentials or user accounts can allow an attacker to incur substantial charges from third-party services, such as long-distance or international calls. It is increasingly common for telecommunications providers to use VoIP telephony over public and dedicated IP networks as a backhaul to connect switch centers and interconnect with other telephone network providers; this is often referred to as IP backhaul. Hosted systems are also often better suited for personal or smaller VoIP implementations, where a private system may not be viable for these scenarios.
In addition to VoIP phones, VoIP is also available on many personal computers and other Internet access devices. A VoIP multimedia gateway controller (also known as a Class 5 Softswitch) works in cooperation with a multimedia gateway (also known as an IP Business Gateway) and connects the digital media stream to complete the voice and data path. When using VoIP, you'll need interfaces to convert telephony traffic and allow radio and telephone users to communicate with each other. VoIP uses protocols such as the common open policy service protocol, common communication over IP, the dynamic host configuration protocol, and the extensible messaging and presence protocol, among others.
While there are still many use cases for private or local VoIP systems, the general market has gradually shifted to cloud or hosted VoIP solutions. VoIP itself isn't necessarily too complicated, although it's easy to get stuck with overwhelming technical data and what essentially reads like jargon to the average person. These emergency services are provided by VoIP providers in the United States through a system called Enhanced 911 (E91), based on the Wireless Communications and Public Safety Act. .
