CallHarbor - Intermittent Inbound Calling Failures - Verizon Wireless Subscribers – Incident details

The issue affecting inbound calls from Verizon Wireless subscribers has been resolved. Verizon has implemented a routing change that has corrected the problem, and our engineering team has confirmed that call completion rates have returned to normal levels.

Our internal CallHarbor network remained fully operational throughout this incident. The root cause was identified as a routing configuration issue within Verizon's network that was affecting calls destined for our upstream carriers.

We will continue to monitor call quality and completion rates closely over the next 24 hours to ensure stability. If you experience any further issues, please contact our support team.

We appreciate your patience as we worked with our carrier partners to resolve this matter.

Due to the root cause lying outside of the CallHarbor network, updates from external carriers may be limited, but our team continues to monitor the situation closely. We have received an update that Verizon is aware of the issue and working towards resolution. We will continue to share further information as it becomes available.

Upstream carriers have identified the cause and are currently working toward a resolution. This issue remains intermittent and appears limited strictly to Verizon Wireless subscribers; calls from all other service providers are completing at normal rates with no signs of impact. While this disruption is occurring outside of the CallHarbor network, our teams remain fully engaged with our carrier partners to monitor the situation. We will provide further updates as we receive them.
