This page aims to provide the basis for understanding VoIP protocols and what defines them. With VoIP phone systems acting as the backbone for most businesses, most users will take these systems for granted. This is very normal, and in fact, many users will go through their day without understanding exactly how their systems are working. If you truly want to ensure the best solution, service, and system for your business, understanding what you are getting into can go a long way. VoIP itself isn’t too complicated, and at the end of the day, it’s most important to understand the protocols and standards in which our most loved systems operate.

By uncovering the knowledge of how VoIP systems work, your business can adopt all the features and services that are needed to increase sales, customer satisfaction, and communication methods.
VoIP stands for Voice over Internet Protocols, and the word “Protocol” is the most important part of how the entire system works. Essentially, VoIP system is a method of transferring audio and video across the internet. Sending data, messages, emails, videos or audio files over the internet isn’t as simple as you think, and all this is done through protocols. Simply put, a protocol is a set of rules that computers will use to govern and explain how data transmissions communicate with each other.
Now that you have a basic understanding of what a protocol is, it’s time to take a closer look at how they help your VoIP systems. There are so many protocols out there, and many have come and gone over the lifespan of your VoIP system. The vast majority of systems will rely on the two main protocols we will list below.
In order to dive more into these two protocols, understanding the term intelligent endpoint protocols is important to note. This term is used to describe SIP and H.323 because of the intelligence needed to locate the receiving devices and establish a data transfer. Both protocols that fall under this term have grown to be more popular in recent years. When speaking about SIP and H.323 protocols, it’s hard to say which one is better and which one is worse, because they both do the job. The only thing that it comes down to is which your business works better with and requires.
Of course, the number of protocols is many, and just because the two listed above are the most adopted doesn’t mean that your systems only focus on them. With the changing times and advances in technology, more protocols will be established for everyday use and utilized for all types of VoIP systems.
