Call forwarding codes for Telstra, Optus and Vodafone, and how to cancel them
Keep the number on your van, your shopfront and your Google listing. You forward the calls you’d otherwise miss to your MAVRK receptionist — one code to switch on, one to switch off. It takes about thirty seconds and you can undo it just as fast. The codes below were read from each carrier’s own support pages on 26 September 2026.
The codes
These work the same on Telstra, Optus and Vodafone mobiles. Replace NUMBER with your MAVRK number in full national format — no spaces, no +61. Dial it like a phone call and wait for the confirmation. Telstra’s own page adds a *11# suffix on mobiles; that version is in the Telstra table further down.
Only calls you don’t answer
**61*NUMBER###61#The safest place to start. Your phone rings first, exactly as it does now. If you pick up, nothing changes — MAVRK only answers the ones you would have missed.
When your line is busy
**67*NUMBER###67#For when you are already on a call. The second caller reaches the receptionist instead of a busy tone.
When your phone is off or out of range
**62*NUMBER###62#Covers flat batteries, tunnels and job sites with no reception.
Every call, straight away
**21*NUMBER###21#Your phone never rings. Use this for after-hours or while you are on the tools — not usually as a permanent setting.
Check what is switched on
Dial *#61# (unanswered), *#67# (busy), *#62# (unreachable) or *#21# (all calls) and press call. Your phone shows whether that divert is active and where it points. Telstra and Vodafone list these check codes on their pages.
Not sure what’s switched on? Clear everything
Dial ##002# to cancel every forwarding rule at once and put your phone back exactly as it was. Nothing about your number, plan or voicemail changes.
Carrier by carrier
Each table quotes the carrier’s own page as written on 26 September 2026, including the suffix Telstra adds on mobiles and the single-hash cancel codes Vodafone prints. Sources are at the bottom of the page; if a code does not take, the carrier page is the one to trust.
Telstra mobile
From Telstra’s small business support page. NUMBER is the number to forward to, including the area code.
| Divert | Turn on | Turn off | Check |
|---|---|---|---|
| All calls | **21*NUMBER*11# | ##21# | *#21# |
| When unanswered | **61*NUMBER*11# | ##61# | *#61# |
| When unreachable | **62*NUMBER*11# | ##62# | *#62# |
| When busy | **67*NUMBER*11# | ##67# | *#67# |
Ring time before the unanswered divert kicks in is 15 seconds by default. Telstra’s page sets it to 15, 20, 25 or 30 seconds with **61*101*SECONDS#. To send unanswered calls back to MessageBank instead, Telstra lists **004*101#, and ##004# to remove that forwarding.
Telstra home phone
From Telstra’s home phone support page: dial the code, key in the number, press #, hang up.
| Divert | Turn on | Turn off |
|---|---|---|
| All calls (Call Forward Immediate) | *21 NUMBER # | #21# |
| When busy (Call Forward Busy) | *24 NUMBER # | #24# |
| When unanswered (Call Forward No Answer) | *61 NUMBER # | #61# |
Optus
Optus documents call diversion through the phone’s own settings rather than a code page: its device guides walk through Settings, then the call or phone settings, then Call forwarding, with the same four options (always, when busy, when unanswered, when unreachable). The generic codes at the top of this page are what those menus send on the Optus network; use the check codes to confirm what is active.
Vodafone
From Vodafone’s call forwarding page, which prints the cancel codes with a single hash.
| Divert | Turn on | Turn off | Check |
|---|---|---|---|
| All calls | **21*NUMBER# | #21# | *#21# |
| When unanswered | **61*NUMBER# | #61# | *#61# |
| When unreachable | **62*NUMBER# | #62# | *#62# |
| When busy | **67*NUMBER# | #67# | *#67# |
Vodafone also lists ##002# to cancel all diverts, ##004# to cancel all conditional diverts, and the short codes 1213 (cancel the all-calls divert) and 1214 (cancel all conditional and unconditional diverts). Its page says there are no additional costs to use call forwarding while you are in Australia.
Which divert to use for a business
Overflow: unanswered only
You keep answering. The receptionist takes the call you are too busy for, the one at 6pm, and the one while you are on the tools. Leave it on permanently.
After hours: all calls
Switch the all-calls divert on when you close and off when you open. Two codes a day, or leave it on over a holiday.
Job sites: unreachable
Basements, tunnels, flat batteries. The unreachable divert catches the calls that would otherwise never ring at all.
Landlines and VoIP are different
Telstra home phones use the shorter codes above. NBN voice and office phone systems usually set forwarding in the provider’s portal rather than by dialling a code — tell us who you’re with and we’ll walk you through it.
Prefer to move the number over?
You can port an existing number to MAVRK instead of forwarding it. It takes longer and involves paperwork with your current carrier, so most businesses start with forwarding and decide later.
Forward the calls you miss to an AI receptionist
Once the divert is on, whatever you do not answer is answered by MAVRK: it quotes from your real services and prices, takes the booking, and texts you what happened. $49/month with 500 call minutes included, 7-day free trial, no card.
Common questions
Does call forwarding cost extra on Telstra, Optus or Vodafone?
Vodafone’s support page says there are no additional costs to use call forwarding while you are in Australia. Telstra’s home phone guide says standard call charges apply to the calls you forward. Optus does not state a figure on its device guides; check your plan. Forwarded calls to a MAVRK number are ordinary calls to an Australian number.
Can I forward only after hours?
The codes have no timer, so there are two ways. Leave the unanswered-only divert on all the time: your phone rings first and MAVRK takes only what you miss, day or night. Or switch the all-calls divert on when you close and off when you open, one code each way.
How do I check whether a divert is on?
Dial the check code for that divert and press call: *#61# for unanswered, *#67# for busy, *#62# for unreachable, *#21# for all calls. Your phone shows whether it is active and the number it points to. Telstra and Vodafone both list these codes.
Will my phone still ring?
With the unanswered-only divert, yes: it rings exactly as it does now, and the call only moves on when you do not pick up. On Telstra mobiles the ring time before that happens is 15 seconds by default and can be set to 15, 20, 25 or 30 seconds with **61*101*SECONDS#.
How do I cancel everything and go back to normal?
Dial ##002# to cancel every divert at once. Vodafone also lists the short codes 1213 (cancel the all-calls divert) and 1214 (cancel all conditional and unconditional diverts). Nothing about your number, plan or voicemail changes.
What number do I forward to?
Your MAVRK receptionist number, shown on the Channels page after you sign up. Enter it in full national format with no spaces and no +61. You can also keep answering yourself and forward only the calls you miss.
