2023/03/02 - Urgent maintenance, 2 March
After 5:30 on 2 March, the phone system will need to be rebooted.  We expect that all phones (IP telephones and emergency phones) will be unable to make or receive calls for a period of around 15 minutes.  Phones will likely show a message reading "Discover 146.231.128.90" during that time. We had hoped that the work done in the would've resolved the PBX issue we've identified, but unfortunately it did not.  It is now urgent to resolve this as there is reason to expect that the issue may impact normal functioning of the PBX next week.  Our PBX support provider and the software vendor will be on hand this evening to resolve the issue.
