CloudPBX calls failing after -30 seconds

Resolved after 1 hour 9 minutes, affecting CloudPBX, on January 15, 2026.

resolved Jan 15, 2026, 03:37 AM UTC

What happened: Some voice calls were disconnecting approximately 30 seconds after being answered. Who was affected: A subset of users connecting through certain network configurations (carrier-grade NAT). Root cause: A network address handling routine was not correctly processing connection details for some network topologies, causing call signalling to be misdirected due to a change to enhance logging for certain transactions. Resolution: Configuration updates have been applied to correctly handle all NAT scenarios. Normal service has been restored.
