Telstra admits missed-call alerts are a glitch

Telstra blames glitch for false missed-call alerts, dismissing hacking fears among confused customers and officials

Telstra customers experienced confusion due to a surge of false missed-call notifications, raising concerns over potential hacks.

The company, Telstra, clarified it was not a cyber attack but a glitch in their Messagebank voicemail service.

These notifications affected high-ranking officials, creating fears of compromised government phone systems.

Telstra explained the issue related to previously missed calls and has since been resolved.

⚠️ We’re aware of some customers receiving a number of delayed missed call and voicemail notifications arriving all at once. This is due to an issue with our MessageBank service earlier today, which has now been fixed. We’re sorry for how confusing this must be. (1/2)
