How can we make free calls?
As we have already mentioned, the operation of VoIP telephony is based on the use of an internet connection, which transfers established connections. If the transfer takes place within one application (the example of Skype mentioned above ), the connections made are not charged with any costs. It is no wonder that developers willingly created various messengers based on VoIP networks. The created messenger can easily be spread to a specific group of people, and then everyone will be able to make free calls over the internet.An equally effective, though somewhat prosaic way is to use Skype itself. The application has been constructed in a very user-friendly way, so nothing stands in the way to create your own network of contacts on its basis. It is worth adding that the program itself is extremely popular all over the world, which additionally promotes contact via VoIP.
VoIP gateway, i.e. an alternative to the telephone
Of course, free use of internal VoIP telephony requires proper configuration that will ensure proper operation of the entire system. Its extremely important element is the so-called VoIP gateway .Although the basic tool for configuring the network is a VoIP phone , but its purchase is not obligatory, because all the functions of the phone can be taken over by the aforementioned gateway. In the earlier part of the article, we mentioned that using instant messengers is a great way to make free calls. Meanwhile, the VoIP gateway allows you to connect to the network, which is done without the help of a computer.
The device acts as a kind of "transformer" because the telephone signal is transformed in such a way that it can be sent via VoID. The VoIP gateway itself is a relatively cheap device, the cost of which rarely exceeds PLN 200.
