Why is ISDN switching off?
As with all technological advancements, progress requires change. The infrastructure that underpins ISDN has been significantly upgraded since it was first launched in the 1980s and big market players like BT and Deutsche Telekom have invested heavily in VoIP. By moving all of their services to IP, providers will be able to focus their resources on a technology that will meet the demands of businesses in the future.
What are the alternatives?
The future of communications lies in VoIP and SIP such as (3CX). Using just an active internet connection, VoIP enables voice and video calls on a global scale. This significantly reduces call costs for customers and also makes it far easier to administer clients’ systems as there are no physical lines to be installed.
