Business Challenges

Before partnering with Telecom Resource, a UK telecommunications provider, the Trust faced several critical infrastructure and operational challenges:

  • Security and compliance: The Trust needed a secure voice platform that met strict NHS standards and enabled remote access.
  • Limited scalability: A future-ready solution was essential to support a 3,000-user UC transformation across the Trust.
