Recently, the term “IP telephony” has been actively “forced” on the telecommunications market. Companies experienced a boom in office "mini - automatic telephone exchanges", when a box weighing 5 kilograms seemed to be the peak of compactness, manufacturability and status. But with the development of the Internet, corporate data networks and other IT stuff, it appeared, a technology that turned the game - IP - telephony.

So, friend, IP - telephony is the same thing. Only instead of the https protocol, the SIP (Session Initiation Protocol) protocol is used, for example, and data packets are filled with information about who is calling where.

When making a call via IP - telephony, your voice is also transmitted through information packets, but only using a different protocol - it is called RTP (Real-time Transport Protocol). Learn more here: https://callgear.com/vpbx/.

We can safely say that the term IP telephony itself is a marketing bullshit. Calls over data networks work within the framework of the same model (it is called the OSI model, read the link, it is useful) as normal traffic, but they simply use other protocols, of which, within the framework of this overdofig model.

IP - telephony is simply a separate set of protocols and standards within the network description model (OSI model). For a better understanding, the term VoIP (Voice over IP) is well suited, which literally translates as "voice over IP". And yes, VoIP and IP telephony are one and the same. Next, we will reflect on what profit IP - telephony gives for ordinary users, in comparison with analog communication, digital signal transmission, linking two cans through a string and pigeon mail.
