Meaning of IP Telephony The Rise of a Different Technology!
Many people can be intimidated when they hear the term IP, but the truth is something very simple, in practice this technology integrates voice and data services in the same functional network (unifies voice, video, data, in the same Internet network). This is why it is sometimes referred to as IP convergence.
It is necessary to understand what the VoIP telephone system is, what is it and how does it work? In order not to present problems in the final result of the tutorial.
These elements together allow us, as you have already deduced, to obtain a telephone service, which allows communication (this system is mostly used by companies), its main elements would be: IP PBX, IP Gateway, and the different IP phones.
What is needed?
Basically it simplifies the management of the telephone network in the company, that is unites the different locations as well as (mobile) workers.
It creates a centralized management based on a single provider, and within the company it grants free calls, gives access to advanced functions such as voicemail, IVR, CTI, etc.
It also optimizes communication lines (cleaner, safer and more efficient), as well as providing complete numbering plans. If you use the best IP telephony providers, you will have greater benefits.
How does it work?
This is even simpler than the above for the proper use of an IP telephony service, you should know the following, IP telephony uses data networks to generate voice calls, which end up being encrypted into an analog signal. Something different than how the VoWiFi calling service works.
This signal is converted into data packets to be sent over the Internet (thanks to VOIP technology). In other words, it works like a sent email through the company or the person to whom it is addressed.
To make it even easier and your best understanding, the step by step would be:
- Pick up the phone and dial the other person's
- The operator (the telephone company) intercepts this signal (with a public network) and connects you with the operator of the analog destination (the number)
- The voice is sent as already mentioned in compressed data packets, the telephone operator receives them (in the form of frequencies), and transfers them to the destination where the data is decompressi and your voice is heard.
