What is PBX
It is a private telephone exchange that connects directly with a public one through analog trunk lines in order to manage internal and external calls autonomously. This device is owned by the company that has implemented it.
Once familiar with the meaning of the acronyms, it is easier to know what PBX consists of. It is a system that allows the management and administration of telephony within your private company, that is, the entry, distribution and exit of calls made within it.
The main advantage of the VOIP Phone System is that it is a technology that uses the Internet either through LAN networks or WAN networks as the main way to make phone calls. Therefore, the voice is going to be digitized and will later be transmitted in the form of digital data packets.
With the use of this platform, it is possible to use softphones, IP telephones or conventional telephones. It all depends on the equipment manufacturer. They work just like traditional phones but with updated features and greater functionality.
Characteristics of PBX

How does it work?
As we already know, the virtual PBX is a private telephone system that, without the need for physical equipment or installations, is inserted into your company to facilitate communication between people inside and outside of it. It works as follows:
● Incoming traditional PBX calls:
This type of system allows the transfer of calls from a public switched telephone network to a private one of the same style. Incoming calls are routed through a switched system to a private number telephone within the same system.
● Traditional outgoing PBX calls:
Internal telephones on this type of network must enter a code, which is usually 0 or 1, in order to gain access to an external line. Once the private line has established the connection with the external line, the user can make the call normally.
● Internal PBX calls:
The difference of the virtual pbx is that the calls are made through internal private telephone lines and through switches. It should be noted that they work in the same way as the private lines of a traditional network.
● Traditional PBX technology:
Traditional systems started with analog technology and had a limited number of phone lines. Over time they have been supplanted by digital switches so they can support higher density internal, external, and long-distance telephone lines.
● IP PBX:
Now, if we add the IP protocol "Internet Protocol" with the PBX, we have as a result the IPPBX or IP/PBX which stands for "Internet Protocol Private Branch Exchange"
