IP-telephony with their own hands: ways to connect, configure

Recently, SIP communication has become widespread. It becomes more popular every day, so many users need to learn how to create and configure their own networks. Of course, a professional in this business will cope with such a task in a few minutes, but what about ordinary people? First, you need to understand the concept of IP-telephony. What this is and how it works is described further in the article. The main issue under consideration is the problem of creating a connection with one's own hands with minimal expenditure of funds or completely free of charge.

What is IP-telephony?

This type of communication arose in 1999, respectively, is considered one of the youngest. It was then that the SIP protocol was approved, which laid the foundation for the development of the type of telephony described. His progenitor and predecessor can be considered the connection of H.323. However, it is currently used as rarely as possible. This protocol differs from the modern one in that it does not save traffic, is in itself quite complex and does not support human mobility.

SIP Protocol

The IP telephony network, namely the SIP protocol, is considered to be simpler and more flexible. Due to it, you can save a lot of traffic, and most modern devices and applications can work on it. Everyone who uses this protocol gets his (unique) ID. Telephony allows free users to navigate the planet without changing this number.

The protocol allows a person to call, communicate via video communication, transfer various files, messages, and also play online games. In order to perform some of the above actions, the protocol is accessed on the Internet, but for others, a special IP-telephony gateway is used (and it is not one).

Work principles

In order to use this type of communication, an ordinary person does not need to study its principles of work. Moreover, he does not need to try to delve into how exactly this or that protocol functions. Users are usually interested in questions about the cost of such services, the availability of additional options and so on. However, for those who reveal the desire to create such a connection with their own hand, such as IP-telephony, what it is and how it works, these are quite topical issues.

Consider the principles of the network through the VoIP protocol. For an explanation, let's take two phones connected with it. While the gadget is in the standby mode, it is connected to the Internet and connected to the other by the operator's server. Immediately after the subscriber calls the interlocutor's internal number, the protocol will establish his location and send a special signal. Communication on the network occurs immediately after the subscriber receives a call.

Accordingly, we can conclude that this action (like all the others) occurs via the Internet, without the help of a mobile operator. That is, subscribers pay only for traffic. Often it is free.

VoIP-telephony allows you to call a subscriber who is with an interlocutor in one network. In this case, SIP-ID is used, that is, unique numbers of each. It is possible to call a subscriber from another network. Then a special identifier called a URI is used. It looks like an email. You can also call from both VoIP numbers to mobile phones and landlines, and vice versa. Such calls are made through special gateways. This allows you to make calls over the Internet, saving on the services of a mobile operator.

The program for IP-telephony makes it possible to safely travel around the world. It will allow you to call anywhere in the world where there is a connection to the Internet. Tariffication will not change.

It should be noted that calls that take place within the same network are free of charge. In this case, the location of the interlocutors does not play any role. The same is true with direct numbers. One subscriber can be in Kiev, another in Seoul. Tariffication will be the same, and the quality of communication at the highest level. A similar property is called mobility.

Cost of IP-telephony

To be engaged in creation of such type of communication as IP-telephony with own hands is an excellent solution, but before you get down to business, you need to find out how much it costs for ordinary users. It is worth noting that this nuance is quite relevant. VoIP-telephony has spread to the whole world. Due to what? It not only allows you to save money, but also gives excellent quality of communication and so on. This protocol also provides free calls to a subscriber who is registered with the same provider.

Everyone knows how traditional traditional telephony works. The further the interlocutor is located, the more expensive will be the communication minute. IP-telephony for free allows you to talk with a person who is on the other end of the planet. No need to pay for the transfer of voice data and connection. Additional charging is not carried out. Due to this, the fee for calling a subscriber who is in another network and registered with the "left" provider will be much lower than that of a normal mobile operator.

For calls within the network, payment is not made. In the main part of incoming calls, they also do not have to give money. For stationary and mobile numbers, a fee of about 40 kopecks per minute is charged. This is quite a bit.

For using direct numbers you will need to pay. The exact cost can not be said, but it is small and is monthly.

How to configure IP-telephony with your own hands: general information

Everyone who has a landline phone at home knows how to conduct a traditional connection. It is necessary to write an application to the company of the desired provider, wait for its consideration. After that, we will have to wait for a special line or equipment to be installed to operate the device.

Connecting IP-telephony is much easier, it can be done independently without the help of the provider and professionals. What is needed for this?

For the stable and good operation of the network, the Internet is necessary. Its speed should not be less than 100 Kbps. You need a computer or a phone that works with the VoIP protocol. It is from them that the call will be made. You also need to create an account with the provider. All this does not require any cost. The only costs will be to purchase the already described type of apparatus, if it is not. Further we will consider in more detail the process of connecting this type of telephony.

The first stage is the choice of the provider

IP-telephony setup begins with the choice of the provider. It is necessary to look at the reviews for each one available. The provider should provide the lowest possible price for calls and good quality of communication. If you want, you can pay attention to the ability to communicate with additional numbers, hold calls and so on. The support function of the second line will be superfluous. Basic subscription options offered by providers are free of charge, as a rule, have a low level of tariffication.

Most consumers recommend using Comtube services. What do I need to connect? You should register on the site, having invented a unique login and password, replenish the internal account. This completes the connection. What does the user get after these actions? He gets an active account, which allows you to make intranet calls. The user receives the subscriber ID. He is also allowed to receive incoming calls.

Paid services

To make a call, you need to refill your internal account. After this operation, IP telephony systems will give access to calls both within the Russian Federation and abroad.

If you want, you can purchase a direct number. It is assigned to a certain city. There are about a thousand of them. Why is it necessary? You can, while in Russia, respond to calls that go to an American number. This allows you not to spend a lot of money and save traffic.

The second stage is the need for a phone

We continue to create such a connection as IP-telephony, with our own hands. In order to take calls and make them, you need a special technique. You can do this either through computers or through special VoIP phones. Below consider the nuances of using both options.

Computer programs

When using the first option, it makes sense to install the software. It simulates a stationary device. The IP telephony server easily connects to the device after making settings. This allows you to make and receive calls. But when using a computer, you must have a headset.

The downside of this phone is that the program should always work in the background, and the PC should always be in the active state. That's why the most convenient is a SIP-phone. Next, let's talk about it.

Work with SIP-phone

SIP-phone costs at least 2 thousand rubles. For such a small price, you can purchase a standard device that supports the protocol. Even budget phones have noise cancellation, call hold, are able to function with hands-free calling and conferences. But the determinant of the number is not here.

More expensive options provide the most convenient use of telephony. As a rule, such devices are universal. What does this mean? The fact that they are able to work with IP-telephony and with urban networks. Often such devices support the functions of determining the number, using several communication accounts. They allow you to work with additional wireless handsets, have an impressive in size phonebook and a color display.

The third stage is the VoIP phone setup

IP-telephony with their own hands is created quite easily. One of the stages is the adjustment of a stationary device. This is what makes it possible to receive and make calls to subscribers. And you need to adjust both computer programs and fixed telephones. An explanation of the steps for changing parameters is done using the example of the Comtube provider. In order to enter the necessary menu, you should find the category "General" in the "My profile" section. We are interested in "Basic IP-telephony settings".

There it is necessary to register the login and password of the account, the address of the server and the number of special ports. There you should enter your personal account. If there are any problems, you can contact the service center. It will help you cope with problems. However, often the configuration of programs and phones is without errors or errors.

The fourth stage is the use of several phones

Some families need several devices for comfortable work with telephony. It should be noted that in order for the two city devices to function, they will have to create separate lines and conclude a couple of contracts. This requires a lot of money, time and nerves, as in the Russian Federation providers have been considering applications for connection for quite some time.

Digital telephony makes it easier to use multiple devices. When you register an account, many lines are created immediately. They give the opportunity to simultaneously receive and call from all. However, this is not available in the "Base" tariff, but in the "Premium". Subscription to it is a little more expensive, but for busy and serious people who constantly talk on the phone, it will be suitable. This tariff supports the creation of up to 100 lines at a time. Most often these services are used by offices.

In order not to buy several separate phones into the apartment, you can buy a device that supports the work with additional wireless handsets. Each of them is allowed to determine on the "own" line. More expensive models are able to work with several accounts and optimally distribute them in automatic mode between the tubes.
