Telefonieren mit dem Laptop, also known as laptop calling, is the ability to make and receive phone calls using a laptop computer. This is achieved through the use of a VoIP (Voice over Internet Protocol) service or software, which allows users to transmit voice data over the internet.
Laptop calling offers several advantages over traditional landline or mobile phone calls. These include the ability to make calls from anywhere with an internet connection, the ability to use video conferencing, and the ability to integrate with other computer applications. Additionally, laptop calling can often be more cost-effective than traditional phone calls, especially for long-distance or international calls.
