Why Change to Our NetX SIP Platform?

The UK is switching off ISDN and PSTN services between 2025–2027. Your current landline-based systems will stop working, and many businesses are still using rigid, traditional PSTN or SIP solutions that:

  • Depend on external support for changes
  • Lack flexible disaster recovery options
  • Expose you to fraud and spoofing
  • Provide poor transparency and control
  • Lack modern value added network based applications

NetX solves all of these challenges - and more - in a single, future-ready platform.
