Voice over IP (VoIP) has established itself as a ground-breaking technology that has fundamentally changed the way we communicate. By using the internet to transmit voice information, VoIP offers a flexible, cost-effective and expandable alternative to traditional telephone networks.
In this blog post, we will look at the key aspects of VoIP, from the technological foundations and how it works, to the benefits and challenges that this modern communications solution brings. Discover how VoIP has the potential to revolutionize both personal and business communications.
VoIP is changing voice communication over the internet in a positive way. It does not use traditional telephone networks such as PSTN or ISDN, which run over copper wires. Instead, the infrastructure of Internet-based networks is used.
The Internet Protocol (IP) has established itself as the standard, as it now also transmits voice information. It was initially only developed for the exchange of data packets in computer networks. It does not matter which end device is used for communication as long as there is an internet connection. This allows more flexibility.
VoIP works as follows: necessary information (voice and control information) is transmitted via a network that is also used for data transmission.
The transmission of voice over the Internet is made possible by converting audio signals into digital data. These are then sent as packets through the network.
Codecs can be either hardware or software-based and compress large amounts of data in order to optimize bandwidth usage, but this can have an impact on voice quality. In addition, DSL routers or VoIP-enabled cable modems are used to connect phones to broadband connections. This bypasses the traditional telephone networks. VoIP servers, broadband Internet access, a VoIP provider or gateway and VoIP devices are also required for use.
VoIP has many functions, e.g. audio and video calls, voicemail, instant messaging, emails or SMS. VoIP also offers extended functions such as call recording, individual caller ID and voicemail-to-email. Consumers and companies therefore benefit from improved communication and additional functions.
VoIP brings with it a number of advantages, but also disadvantages that affect both businesses and private individuals.
