Scheduled - Zoom is continuously optimizing our global footprint to improve performance and availability for our customers. With this, starting Dec 01, 2025, Zoom Phone and Zoom Contact Center plans to start shifting traffic from old data centers to our newer data centers with weekly continuous migration changes.
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 which will assist customers.
We wanted to remind customers for optimal experience, and to avoid any potential issues, to please allow Zoom Traffic to all subnets located on our Zoom Network Firewall page. This includes specific sections for Zoom Phone & Zoom Contact Center.
Customers would see the change in the admin portal of their sites showing the new sip zone after those changes if “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 hour change windows to reduce impact.
Here are sip zone name mapping for old data center and new data center in the cluster:
Zoom Phone
US West (N. California) -> US West (RHV) US East (New Jersey) -> US East (BWI)
Zoom Contact Center
us-gov-west-1 -> US West (RHV) us-gov-east-1 -> US East (BWI)
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 in any way by these changes. Customers should not need to do any active changes if they are following the guidance as provided in Zoom network firewall or proxy server settings. For any questions or concerns, please contact your account team or Zoom Support.
FAQ What is changing? Zoom Phone and Zoom Contact Center are shifting traffic from the old data centers to the new data centers
When is this planned? Starting Dec 01, 2025 and on a weekly basis until all traffic moved over
Do I need to update my firewall or other systems to allow communications with these new data centers? Following the guidelines in Zoom network firewall or proxy server settings will help customers connect to the available Zoom data centers globally. As Zoom scales to meet customer demand and enable future products, platform IP addresses and network ranges will change to accommodate service growth and seasonal load spikes. As these services and ranges frequently evolve, Zoom does not provide specific IP address ranges assigned to geographical locations.
Will this be the only change for Zoom Phone and Zoom Contact Center? As Zoom continuously optimizes our global footprint to improve performance and availability, there will be additional changes like Generic Device, BYOC, BYOP migration and will be communicated separately. Following the guidance in Zoom network firewall or proxy server settings will help customers connect to the available Zoom data centers.

Update -
As a reminder, the previously issued Single-Sign-On (SSO) certificate for 2024/2025 will expire one week from now, on January 9, 2026.
Zoom recommends that customers who do not utilize an IDP that supports dynamic metadata refresh manually update their certificate to the new certificate (with an expiration date of January 11, 2027) before January 9, 2026.
If you are having difficulty rotating the certificate, please contact Zoom Support.

Scheduled -
Zoom will be making the new Service Provider certificate available on December 12, 2025, ahead of the expiration of the previously issued 2024/2025 certificate on Friday, January 9, 2026.
No action is required for customers using an identity provider (IDP) or configuration that supports dynamic metadata refresh, as your IDP will automatically download the latest Zoom certificate and rotate it into your account’s configuration starting Friday, December 12, 2025.
If automatic update is disabled or your IDP does not support automatic certificate rotation, your organization will need to manually rotate the certificate by January 9, 2026. If the certificate has not been rotated by then, your organization will be unable to utilize SSO services until the certificate has been updated.
