Chorus update

The University's phone system is in the process of being replaced by a new telephone service called Chorus. 

We now have 11,800 Chorus users across the University after the third implementation tranche was completed at the end of June. This represents around 60% of the approximate 20,000 total phones to be delivered and replaced.

While the original plan was to introduce Chorus in six sequential tranches, the project has reduced this to five and implementation should complete in December 2017, three months earlier than originally anticipated. 

By mid-July the business change team will have completed engagement meetings with all re-scheduled units and the technical team expects to complete remediation planning by the end of September.

Bringing completion forward has partly been possible due to the emergency closure of the Tinbergen building (Zoology and Experimental Psychology) that necessitated the early delivery of Chorus to the 800 staff who had to be relocated.

IT Services succeeded in rapidly reconnecting telephony for displaced staff and, because Chorus assigns each individual a unique phone number which they can then access through their ‘preferred device’ (e.g. desk phone, mobile  or tablet), they will now retain that phone number wherever they are located whether temporarily or permanently.
