What is the IP-Range that the Cisco uses for integration of MS-Teams for WebEx calling app ?

We have successfully migrated from HCS CUCM to Webex Cloud Calling. We are also using the Webex Calling Teams add-on, I did not see specific FW rules for that, as Vaijanath mentioned there is one aspect on Microsoft side you need to do.

For all the required FW rules for Webex, the following links can be used.

Push Notifications for Google FCM (https://firebase.google.com/docs/cloud-messaging/concept-options#messaging-ports-and-your-firewall https://www.gstatic.com/ipranges/goog.json)

Hi @Sachin99,

If you are trying to integrate Webex App in MS Teams as mentioned in below document:

https://www.cisco.com/c/en/us/support/docs/conferencing/webex-control-hub/220504-deploy-and-use-of-webex-call-integration.html

then the IP Range and Network Firewall ports are same for deploying with or without MS Teams. There are no separate IP Ranges for this integration. The IP Ranges and Firewall ports are listed in below document:
