University of Oxford Case Study

The University of Oxford was the first University in the English-speaking world which currently has a student population of over 20,000. A third of the university’s population comes from outside the UK from more than 140 countries and territories.

The challenge

  • The resilience of the outbound call services needed to be increased
  • Reduce the dependency on a single ISDN30 supplier
  • Provide opportunity for future addition of services

The solution

  • Pilot project was trialled for implementation of SIP trunking across the Janet network
  • Redcentric worked alongside Oxford University Computing Service (OUCS) voice experts, Cisco's assigned systems engineer and the Cisco Technical Assistance Centre

Why Redcentric

  • Other suppliers wouldn't provide any voice traffic via Janet
  • Redcentric is a Janet-connected provider
  • No minimum contract term or SIP trunk channel charges during the trial
  • Paid its own costs and OUCS did the same






  • SIP Trunk over Janet
  • Use of Redcentric/Janet Interconnection
