Maintenance
Scheduled Maintenance
Scheduled Maintenance Jun 21, 2024 22:00 - Jun 22, 2024 04:00 MDT
Purpose: Patching and preventative maintenance on multiple systems.
Systems Affected:

Fax:
-MasterFax & CT Cloud Fax - General Server Maintenance
***Possible Impact: MasterFax & CT Cloud Fax - Customers will experience interruptions to both MasterFax and CT Cloud Fax services during the Maintenance Window.

Cisco:
-HCS Device Pack upgrade to 12.5(1.19210-2)
***Possible Impact: Cisco Call Manager/Phones - CallTower will be loading a new Device Pack from Cisco to HCS/CUCM. This includes new Firmware on select models. A reboot of the Cisco Unified Communications Manager is required. Your phone will re-register to the next server in the Server list. Calls in progress 'should' remain up until the call has ended. Phone will most likely re register multiple times during the MW time. This is expected behavior.

Completed - The scheduled maintenance has been completed.
Jun 7, 02:00 MDT
In progress - Scheduled maintenance is currently in progress. We will provide updates as necessary.
Jun 6, 22:00 MDT
Scheduled - Scheduled Maintainence by Calltower's partner, Aptum. Please see details below.

Change Impact: Ashburn Equinix POP facility

This maintenance is scheduled to upgrade the code on the first of two routers in our Ashburn Equinix POP facility. During the maintenance, the VPLS or Cloud Connect solution in this Router will be unreachable for about 30 minutes. The 4-hour maintenance window is to account for the work necessary to carry out these upgrades, and it is required to ensure we keep running a reliable code and we stay and up-to-date with our vendor's updates

This will have a potential impact on Calltower's New York SBC signaling IPs 64.34.45.0/24 and 65.39.213.0/24

Aptum and the appropriate staff will be present for the entire duration of this maintenance window. If you have any questions or experience any issues after the end of the maintenance window, please open a ticket through Calltower Support. Thank you.
