Voice communication conducted via internet protocol (IP) networks, circumventing traditional cellular networks, constitutes an alternative method for establishing connections. Several applications and services facilitate this type of communication, enabling users to converse without incurring standard mobile carrier charges. A typical implementation involves a smartphone connected to a wireless internet access point transmitting voice data in digital packets.
The proliferation of accessible wireless internet infrastructure has rendered this communication method increasingly relevant. Benefits include cost savings, particularly for international calls or for individuals with limited cellular plans. Historically, this communication method emerged as a means to bypass expensive long-distance charges, evolving alongside the expansion of broadband internet and sophisticated mobile devices.
