Switch to IP technology advances

Thanks to IP img technology, phone calls are no longer transmitted via analog channels or using ISDN img technology but in the form of data packets over the secure Deutsche Telekom network, a method that has been the standard in online and mobile communications services for some time now. The switch to IP-based lines is the basis for faster internet connections and increasingly complex applications. We will thus meet the growing demands of our customers. At the same time, energy use with IP technology is considerably lower than with the network technology previously used. The switch therefore also helps us decrease our CO2 emissions.

In total, we have already switched 20.3 million lines to IP, two million of which are for business customers. In the other EU countries, we also increased the number of IP lines. In Croatia, Montenegro, North Macedonia, Slovakia and Hungary, all lines have already been switched to IP. In Greece, 74 percent of the lines are running on IP technology, and in Romania the figure is 47 percent.
