The concept of VoIP dates back to the early 1990s, with significant developments occurring when the first VoIP software, called 'VocalTec', was introduced in 1995. This technology gained popularity in the late 1990s and early 2000s as broadband internet became more widely available, leading to the establishment of numerous VoIP service providers. Over the years, VoIP has evolved, becoming a critical component of modern telecommunications with applications in both personal and business communication.
