On March 10, voice call functionality was unavailable across the platform. During this period, all incoming voice calls failed.

The incident was caused by a configuration mismatch following a routine update. The voice service continued using outdated configuration values, resulting in authentication failures and service disruption.

The issue was resolved by:

• Updating application configuration to the correct values

• Redeploying services to apply the updated configuration

All voice call functionality was temporarily unavailable for approximately 30 minutes. 

Preventive Measures

We are implementing the following improvements to prevent recurrence:

• Automating configuration synchronization and deployment processes

• Enhancing alerting to ensure incidents trigger on-call notifications

• Establishing a standardized process for configuration updates

Improving observability and debugging capabilities for faster diagnosis
