Highlights
Historical Events
VoIP Origins
The concept of VoIP began with early digital voice experiments. Initial efforts focused on converting analog voice signals into digital data for transmission over networks.
Internet Protocol Standardized
The standardization of the Internet Protocol (IP) was crucial. It provided the foundation for transmitting voice data over the internet, enabling the development of VoIP technologies.
First VoIP Software
VocalTec released the first VoIP software, 'Internet Phone.' This marked the beginning of consumer VoIP applications, allowing users to make calls over the internet.
H.323 Standard
The ITU introduced the H.323 standard, which provided a framework for multimedia communication over IP networks. This standard helped in interoperability and growth of VoIP.
