Dial 321
Change your Optus voicemail greeting
On an Optus mobile you record the greeting by calling 321. Optus also offers time-of-day greetings, which suit businesses well: one greeting for business hours, another for evenings. On Optus Loop you can upload a file.

Time-of-day and group greetings
Optus describes both options for home phone and mobile voicemail.
Up to four greetings on a schedule
In the Greetings menu, press 5 for the greeting schedule. Record up to four greetings, numbered 1 to 4, then set days (1 for Monday to 7 for Sunday) and time periods, and enable the schedule with 5. Where no greeting is set, the main greeting plays.
Greetings for groups of callers
In the Greetings menu, press 7. You can record two group greetings and add the numbers that should hear them, for example your key accounts.
Optus Loop: upload a file
For Optus Loop with RingCentral, Optus describes three ways to set a custom voicemail greeting in the desktop and web app: record with the computer microphone, have the system call your phone, or import a WAV or MP3 file. The path is Settings, Phone, Voicemail greeting, Custom, Importing.
An older Optus Loop guide from 2021 asks for a WAV file in CCITT µ-law, 8 kHz, 8 bit, mono, with separate greetings for busy and no answer. Our free audio converter creates that format (the converter page is in English).
Mobile: playing the file into the call
Optus mobile voicemail does not describe a file upload. Play the MP3 from your computer into the call when 321 asks for the greeting. Keep the room quiet; some sound quality is lost on the way.
Two greetings for a schedule
