IP telephony, also called VOIP. It is a modern type of high-tech communication that allows you to use your phone over the Internet or any other IP network to make calls, video communication, international and long distance faxes in real time.
It consists of a telephone connection that can be classified according to a series of signs, but it is generally divided into two types: using software or a special telephone and communication using cards.
IP telephony stands for a set of communication protocols, VoIP equipment, software, technologies, and methods that provide powerful, non-traditional telephone communication functions.
The quality of voice communication over the Internet depends on the passage of a digital signal, which carries data packets from one point to another. It is a technology that provides a fast, convenient and economical service.
To learn more about IP telephony, stay with us here. We will show you the difference between IP and analog telephony, how it works, its advantages, costs and how to hire the service. Discover this new form of communication.
Difference between IP and analog telephony
The difference between IP and analog telephony is the lack of a cable and a traditional telephone, which are used by analog telephony. Instead, for the organization of telephone communication through IP networks, special equipment is used as IP telephony gateways.
IP telephony does not have regular telephone communications, with the usual devices and cables. Communication takes place through devices that have direct access to the Internet. It can be not only computers, but also tablets or mobile devices. Audio headphones are also required if the computer does not have speakers and a microphone.
IP telephony how it works
IP telephony works as follows. The voice on the computer (or on the IP phone) is converted into a digital signal and transmitted to the other party's computer (IP phone). There, it is converted to an analog signal and played through the speaker.
In case the call reaches a normal telephone, the signal passes through an IP gateway which converts a digital signal (VoIP) into an analog one. The same happens when making calls through IP telephony to mobile phones.
The signal is transmitted digitally through the communication channel and, as a rule, it is converted (compressed) before transmission to remove excess information and reduce the load on the data transmission network.
Upon reaching the recipient's address, the transmitted information is decoded again, acquiring the format of the usual voice signal. All of this happens in a matter of fractions of a second, in real time with no loss of transmission quality.
IP telephony advantages
The main advantage of IP telephony in reducing communication costs. In many cases, we can have free IP telephony. In addition, there are no borders in terms of communication. The simplicity of the configuration and the level of security are two other great advantages that this technology has. It also has 5 additional benefits:
- Accessibility and mobility. It can be accessed virtually regardless of geographic location. You only need high-speed Internet access
- High potential. Possibility of rapidly expanding configurations, introducing new services.
- Confidentiality and security. Thanks to encrypted communication channels, access to information by third parties is closed
- Opportunities. Unlimited data transmission. With IP telephony, you can organize audio conferences, send information in text and other formats.
- Optimal solution. Offices, companies and organizations benefit thanks to its versatility, it allows you to make the most of communication without making any effort.
IP telephony costs
By using VOIP telephony, the difference in prices compared to analog communication can be clearly seen. Calls are not charged within the networkThat is, subscribers using the services of an IP telephony provider communicate using software or hardware, saving money.
Since Internet traffic does not have a geographic reference, the distance between the sending region and the information receiving region is also not important, in contrast to normal telephone communication, which operates on the principle of 'the further, the further. expensive". There is no additional charge to send traffic to any destination.
When making calls to mobile or landlines abroad or in other regions, the cost of expenses is also an order of magnitude lower than in an analog network (less than 10 euros). There is no fee for a subscriber line, but the truth is, instead, you must pay for Internet use at the provider's rates.
How to contract IP telephony
To enjoy this service you must have: Internet connection, hire the services of a company that operates with the IP telephony service and have the device to make calls. Among the best VOIP operators in Spain are: Monema, Mundo IP, Vozelia, Telsome, Voztelecom and Telefacil.
The operators that provide this service have several quality plans, with fast and efficient support. Choose the one that best suits you. However, the internet support must be adequate, the following are recommended: Fiber, 5G, 4G, ADSL, Satellite, WiMAX and 3G. The devices to make calls must be conditioned for this specific technology, such as: IP phones, IP adapter or ATA adapter and Softphones (program / app).
