TAHAAN is the first VoIP (Voice Over Internet Protocol) application that can be used for both business and personal purposes. It is based on a simple concept, that is, the idea of using Internet as a voice channel. This is possible because the Internet has a good reputation for its security and stability. Moreover, Internet connections are usually good and available everywhere.

With the help of this application, it is possible to make a phone call over the Internet, regardless of the availability of the network or the type of connection (WiFi or mobile data). It is also possible to send and receive SMS messages.

The main advantage of this application is that you do not need to install any additional software on your device, such as a microphone, a telephone, or any other equipment. All you need is a microphone and a computer or a mobile device with a data connection.

It is also possible to make international calls. The rate is fixed and you do not need to pay any additional costs for the usage of this service.
