ProVista (the suppliers of our Telephony system) have advised a reboot of the CUCM cluster.
This will be done this evening between 7pm and 9pm.
During this time the phone system should be considered “at risk”.
When the system comes back on line, some handsets may require a reboot, this is done by simply removing the network cable from the back of the device (if there are 2 cables it is the one NOT going in to your computer, it’s the other one) and replacing it again.
If you experience any issues, please contact Help4u in the usual manner.
