Please be advised of the following Emergency engineering works on the IP Voice Services platform:

Date: 23:00 to 23:59 on Wednesday, 23/01/2013

Purpose

The IPVS Engineering Team will be carrying out works to implement a vendor supplied patch to the Application Server clusters in the Core Voice Architecture between 2300 on 23/01/2013 and 0000 on 24/01/2013 to address the exception observed on 16/01/2013.

Impact

Due to the redundant nature of the platform there is no expected effect to Voice Services, as while an element in the cluster is being patched, its peer will sustain normal service.
