Project Sonus is starting


Project Sonus is starting.

During the summer the University Leadership Team took the decision to invest £1M in upgrading the group fixed line telephony service.

This will result in a complete state-of-the-art Voice over Internet Protocol (VoIP) telephone service, with a new switchboard capability, new improved solutions for clearing and the removal of end-of-life equipment. More details will be available soon on the Sonus programme here.

In order to leverage all of these benefits and more, we must first upgrade our existing VoIP service.  ITS have been working with our Partner, BT iNet in preparing this upgrade, which is now nearing readiness.

Once this upgrade to the latest Cisco Call Manager Server is complete, it will enable more features and allow us to begin the replacement of the Siemens telephone system, enabling us to replace around 2500 telephones around campus and replace the University’s main Switchboard.

Those staff who are already on the VoIP service (those that have a Cisco branded phone on their desk) will experience a small outage whilst the software is upgraded to the latest level.

The switchover will occur between 07:00 and 08:30 on 22nd October 2013. Before this we will freeze changes on all telephony meaning that no telephony changes or additions will be allowed between 16th October 2013 and 23rd October 2013 whilst the system is being prepared. Handset firmware will be upgraded over night between 00:01 and 04:00 on 16th, 17th and 18th October 2013 to enable a quicker change over on 22nd October 2013 – during these periods users should not see any change to the service.

Please email John Rogerson, the ITS project manager, if you have any questions about the project. We trust the new service will offer significant improvements.  Remember to look out for more details via the link above as they are released.
