Zoom for Government is continuously optimizing our global footprint to improve performance and availability for our customers. With this, starting from June 15, 2025, Zoom for Government will be shifting Zoom Meetings, Zoom Webinar, Zoom Phone, and Zoom Contact Center, as well as Cloud Room Connector traffic from old data centers to our newer data centers.
The Zoom Phone and Zoom Contact Center team will start to change the SIP zone from the old SIP zone to the new SIP zone in the backend. We are sending out this notification to inform our customers of this change, along with some reminders that will assist customers.
We want to remind customers that for an optimal experience and to avoid any potential issues, please allow Zoom Traffic to all subnets on our Zoom for Government Network Firewall page. This includes specific sections for Zoom Phone, Zoom Contact Center, and the Zoom Cloud Room Connector:
Customers would see the change in the admin portal of their sites, showing the new SIP zone after those changes if the “Display Custom SIP Zone Options on Web Portal” feature is enabled in Zoom Phone. Customers would not see the SIP zone name in Zoom Contact Center; thus, no portal change for Contact Center customers.
Please note that all hardware phones will automatically reboot when a data center migration is triggered. If you have an ongoing call, it will reboot once the call has ended. Migrations are planned to occur during our weekend off hours and change windows to reduce impact.
To ensure that customers are aware of this change, we are sending out this notification, along with some reminders on allow lists for firewalls or other controls that will ensure customers are not impacted by these changes. Customers should verify that they are following the guidance as provided in Zoom for Government network firewall or proxy server Meeting/Webinar settings, which can be found here: https://support.zoomgov.com/hc?id=kb_article_view&sysparm_article=KB0010104
For any questions or concerns, please contact your account team or Zoom for Government Support.
