This incident has been resolved. As a precaution, tenants continue to run on the secondary voice instance until the root cause analysis can be completed.

The incident was caused by a low-level third-party voice gateway component becoming overloaded, resulting in loss of voice client connectivity for agents. Initial analysis indicates a potential software bug in the affected component related to worker thread collisions under a specific combination of call load conditions. Although warning logs were generated by the affected service, the monitoring system did not detect the condition in time due to vendor-introduced log syntax changes that no longer matched the existing monitoring pattern. Corrective action plan: * Finalize voice gateway component bug assessment and apply fixes. * Update and validate monitoring rules for the new log entry syntax.
