ISDN is Switching Off

  1. What is the ISDN?
    The ISDN or Integrated Services Digital Network is a circuit-switched telephone network system
    that transmits data and voice over a digital line. Put simply, it’s a set of communication standards
    used to transmit data, voice, and signaling.
  2. Why is it 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.
  3. What are the alternatives?
    The future of communications lies in VoIP and SIP. 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 for resellers to administer clients’ systems as there are no physical
    lines to be installed.
  4. Is this a good thing for resellers?
    Absolutely! The ISDN switch off will benefit UCaaS resellers:
    Expect to see an increased interest in VoIP as more businesses become aware of the switch off.
    It’s a big opportunity to migrate customers with outdated on-premise systems to hosted
    systems that generate recurring revenue and additional revenue streams for your business
    On the admin side, VoIP is easier to scale and manage.
  1. How long do I have?
    ISDN is no longer being sold in most regions. The final switch off will happen in most regions
    before 2025.
