Optus reveals triple zero calls from blackout ten times higher than first stated

Optus has revealed an extra 2,000 customers failed to get through on triple zero calls. The count comes from during the outage on November 8 last year. The figure is more than 10 times higher than the number previously disclosed in a Senate Inquiry. The communications giant had initially revealed 228 customers attempted the emergency dial. The new information will be given to ACMA, which is currently investigating whether Optus has upheld its Emergency Service Call Determination obligations.
