We're performing work that may cause some voice calls longer than 4 minutes to disconnect prematurely between 11pm May 16 and 3am May 17 (Sydney time).

New call attempts will not be impacted and all other functions are scheduled to operate as normal so please redial should you experience any interruptions.

Also from midnight to 6am May 17 you will be unable to update call barring, call waiting, call forwarding and caller ID settings.

After 6am you will be able to change these settings as normal so please try again after this time.
