UCaaS: Intermittent Inbound Call Failures

The incident affecting intermittent inbound call failures has been fully resolved.

The issue was caused by a temporary spike in inbound call volume, which briefly exceeded system capacity. Traffic levels have since returned to normal, and inbound calling is operating as expected.

System monitoring confirms stability, and no further impact is observed at this time.

We appreciate your patience during the investigation and resolution.

We have identified the cause of the earlier intermittent inbound call failures.

A sudden and unusually high spike in inbound call volume temporarily exceeded available system capacity on a PSTN proxy server, resulting in some inbound calls failing to connect.

The condition has been fully resolved, inbound calling has returned to normal operation, and our systems are currently stable. We are actively monitoring the environment to ensure continued service reliability.

We are also reviewing safeguards and capacity controls to reduce the likelihood of similar events in the future.

Thank you for your patience and understanding.

We are currently investigating reports of intermittent inbound call failures affecting a subset of calls to our system.

Our engineering team has identified the issue and is actively analyzing call signaling and routing behavior to determine the root cause. At this time, outbound calling and other platform services continue to operate normally.

We will provide updates as additional information becomes available and will share confirmation once the issue is fully resolved.

Thank you for your patience while we work to address this matter.
