How can the Internet be used for making phone calls?

Every Internet-enabled device has its own IP address. This address can be used to send data back and forth between end devices. Unlike conventional ISDN connections, IP telephony uses IP connections to connect to broadband. IP telephony enables new functions and services that are difficult or costly to implement in the conventional telephone network. This makes communication in companies faster and easier and noticeably improves internal processes. With a traditional DSL tariff , for example, several calls can be transmitted simultaneously. This not only makes the management of a company much more communicative, but also improves direct customer business.

In addition to a stable internet connection, a company needs special VoIP-enabled end devices. Calls via the internet can be made either directly from a PC, for example with a headset, or with a telephone, provided it is also VoIP-enabled. However, an even better option is a telephone system from the cloud. It eliminates the need for traditional on-site hardware and cabling because its functions are managed in a provider's data centre. Those who still swear by a locally installed telephone system can, of course, achieve this with IP telephones optimised for hybrid and All-IP telephone systems.
