What is IP telephony
IP telephony is a telephone communication system implemented using Internet channels. Such systems can be found more and more often in organizations of various fields of activity. According to statistics, IP telephony solutions are most in demand for trade and service enterprises.

The system allows you to perform all the functions available to subscribers of a traditional telephone network, namely dialing, receiving calls, recording voice messages. When installing additional equipment, the user can get the opportunity to make video calls, create conferences, etc.

The IP telephony system is a set of software and hardware, the combined use of which allows you to perform specified functions. The design and implementation of IP telephony is carried out individually, taking into account the features of the facility and the wishes of the customer. The complexity of installation work and the cost of the system as a whole depend on the selected equipment.

The system allows you to use all the functions available to the user of a standard telephone network. These include:

dialing;
dialing;
voice communication.
In addition, modern equipment allows you to get advanced features, such as making video calls.

The use of this type of communication is relevant for organizations of various sizes. As statistics show, these are mainly trade and service enterprises. IP telephony is a combination of software and hardware that ensures stable operation of the network as a whole. The development of the project and calculation of IP telephony is carried out individually for each organization, taking into account its features (structure, number of personnel, scope of activity, etc.).

The principle of operation of IP telephony
The composition of the system is selected by specialists individually. The functionality of the system, as well as the speed and safety of its operation, depend on the characteristics of the installed equipment. Despite the wide variety of such systems for organizations, they are united by a common principle of operation.

An incoming voice call is received by a computer or a special telephone. A speaker is used to reproduce the voice.
The system can also work without using a special phone or computer. A regular telephone can be used together with a special IP gateway. The same gateway is used for calls to cell phones.
With the help of a special program - a codec, the voice is converted into an analog signal, and then transmitted via the Internet channel. Using a codec improves the quality of the signal and increases the speed of its transmission.
To improve the security of communication, special encryption programs for transmitted signals are used.
Various additional equipment is used to expand the functionality of the system. Its presence and type are selected at the stage of designing the system depending on the wishes of the customer.

Advantages and disadvantages of using the system
Using IP telephony allows you to improve the quality of services provided by the organization. Implementation of such a system in the company allows you to get the following advantages:

Significant savings. This is especially important for enterprises where many long-distance calls are made. The cost per minute of such a connection is significantly lower than with traditional telephone communication.
Complete confidentiality and security of transmitted information.
The ability to increase the number of lines if necessary. In this case, the subscriber does not incur any additional costs.
High quality of communication, regardless of distance (signal deterioration may be observed in cases of heavy congestion of the communication channel).
The disadvantages of using such a system include the need to purchase special equipment. It should be noted that this category of expenses is one-time. With active use of the system, the cost of the equipment quickly pays off due to savings on communication services.

Features of installation and operation
Design of IP telephony and installation of special equipment is performed by specialists taking into account the features of the facility. For organizations of various sizes, different equipment can be used, which is selected depending on the expected load of communication channels.

Contacting specialists allows you to get high-quality communication and equipment that is most suitable for a given company.

In general, the use of this type of communication provides ample opportunities for organizations. The implementation of IP telephony in organizations allows you to get a stable high-quality signal and at the same time significantly save on the services of telephone providers.

Main elements of the system
Any IP telephony system consists of the following main elements:

VoIP gateway;
access servers;
network administration and control module;
user accounting database;
client terminals.
VoIP gateway is a system of boards (voice and interface) that are connected to each other using a bus. Voice boards are needed to compress voice
