What is ISDN?

ISDN (Integrated Services for Digital Network) is an ideal solution if you want a voice service tailored to your business needs. As well as allowing voice calls and internet access, our ISDN packages also allow you scalability and flexibility allowing you to space to breathe in the ever-changing business world.

Benefits of ISDN

  • FREE transfers and installations*
  • High performance – digital transmission provides better quality calls than a standard telephone line
  • Greater productivity – transmitting voice and data simultaneously allows your staff to do more things at the same time
  • Enhanced availability – unlimited DDIs mean that customers can contact individual members of staff quickly and easily, without the need to go through the switchboard, providing a more personal service
  • Scalability – support business growth by adding more connections quickly, easily and at a low cost
  • Disaster recovery – business continuity options on ISDN 30 ensures calls can be re-routed if the unexpected happens
