Webex Calling offers a Service Level Objective (SLO) for product availability of99.99%. This SLO represents the uptime percentage that Cisco commits to maintaining for the Webex Calling service, ensuring high availability and reliability for users.

Cisco guarantees this high level of availability by utilizing a globally distributed infrastructure and redundancy across multiple data centers. This approach allows Webex Calling to maintain continuous operation even in the event of localized issues or outages, ensuring users experience minimal service disruption.

To achieve and maintain the 99.99% availability, Cisco employs several key strategies:

Redundant Architecture: The Webex Calling infrastructure is designed with multiple layers of redundancy, including network, server, and data center redundancies.

Continuous Monitoring: Cisco continuously monitors the Webex Calling environment for any signs of potential service degradation and responds quickly to mitigate issues.

Automated Failover: In the event of a failure, the system can automatically switch to backup resources without noticeable downtime to end users.

Regular Maintenance and Upgrades: Cisco regularly performs system maintenance and upgrades during scheduled windows to ensure the platform is running on the latest and most secure infrastructure without affecting service availability.

These measures align with Cisco’s commitment to provide a reliable cloud calling solution, making Webex Calling a robust choice for organizations needing consistent, high-availability communication services.
