Set up call forwarding on Optus mobile

Set up unanswered-call forwarding from an Optus mobile to PrimaReply, verify the diversion and turn it off safely when required.

About 5 minutes Updated 4 Sept 2026

Before you begin

  • Copy the connected PrimaReply number from your dashboard.
  • Use the Optus mobile that receives your business calls.
  • Choose when unanswered rather than always forward so the phone still rings first.

Preferred setup on your phone

  1. Open the Phone app.
  2. Open Phone settings or Calling accounts.
  3. Select Call forwarding.
  4. Select Forward when unanswered or No reply.
  5. Enter your connected PrimaReply number.
  6. Enable or save the setting.

Menu names vary between iPhone and Android models. Use the Optus device-help website to select your exact phone when the option is not visible.

Dial-code alternative

On compatible Optus mobile services, open the keypad, dial **61*PRIMAREPLY_NUMBER#, then press Call. Replace PRIMAREPLY_NUMBER with the complete connected number.

Optus plans, voicemail configuration and devices can behave differently. If the code is rejected or the destination is not updated, use the handset-specific Optus instructions or contact Optus rather than repeatedly trying codes.

Check and verify it safely

  1. Dial *#61# and press Call if your service supports status checks.
  2. Open Settings → PrimaReply coverage, select Optus and start the 10-minute forwarding test.
  3. Call the business mobile from a different phone.
  4. Let it ring without answering.
  5. Wait for PrimaReply to show Forwarding verified.

The verification call does not send an SMS or create a customer lead. Normal missed-call recovery begins only when you deliberately switch PrimaReply to live mode.

Turn it off

Return to Call forwarding → Forward when unanswered and select Disable, or dial ##61# and press Call if supported.
