InTechnology has helped the University of Oxford deploy SIP trunking across JANET, the private network for research and education.The national academic network, JANET, provides the connection between the Oxford University network and internet locations outside Oxford.
While the University’s core voice network was highly resilient, all the ISDN30 circuit fibres pass through the same small area of central Oxford. The Oxford University Computing Service (OUCS) was concerned that if there were any problems with these circuit fibres, staff and students at the University wouldn’t be able to make or receive any calls. OUCS therefore decided to see if it was possible to send voice traffic from its Cisco IP-PBX infrastructure over its high bandwidth and physically diverse Janet IP network connections.
Roy Farrow (Divisional product director, InTechnology): SIP trunks offer a host of capabilities above and beyond their ISDN30 counterparts, such as allowing IP-based data services to use the same pipe as a voice service, enhanced disaster recovery features and the flexibility to scale up and down to meet peak demand.
Looking to the future, OUCS is looking to develop the system further and configure other traffic to be routed to InTechnology from its PBX. The new system also offers the University the potential to add remote access to its VoIP system, delivered as an InTechnology-hosted system.
