[Upstream Carrier Outage] Calls to some 1300/1800 services experiencing no audio or failing to connect

Our upstream carrier(s) have confirmed that a small number of 1300/1800 services are affected by an issue at an interconnect point further upstream in the call path, beyond our direct carrier links. Their network engineering teams are investigating and engaging with the upstream party responsible. Most 1300/1800 calls are completing normally.

As this fault sits outside our network and our immediate carriers' networks, resolution timelines are dependent on the upstream provider. We will continue to post updates as we receive them.

We are currently investigating an issue affecting calls to 1300 and 1800 service numbers.

Customers may experience calls that fail to connect, have no audio, or ring without answer.

We have confirmed the issue persists across alternative upstream carrier paths, indicating a broader carrier-level outage. We are actively engaging with our upstream carriers to determine the cause and expected resolution time. Updates will be posted here as more information becomes available
