Forward the calls you miss. Keep the rest.
Conditional forwarding hands a call to Heyline only when your line is busy or nobody picks up. Here is the code for every carrier we have checked, what it costs, and how to undo it.

How do you forward your missed calls to Heyline?
You dial one short code from your business phone. It tells your carrier to hand a call to your Heyline number only when your line is busy or nobody picks up. Your own phone still rings first, your number does not change, and one undo code puts it all back.
Every carrier writes that code differently, so the go-live wizard builds yours with your dedicated Heyline number already inside it. This page is the same list, printed in the open. Read it before you pay for anything, and check what your own carrier charges before you dial.
The codes here come out of the same file the wizard uses, cross-verified on July 17, 2026 against the sources listed at the foot of this page. If you would rather she answered every ring instead of the leftovers, publish your Heyline number and skip the code entirely.
Your carrier’s code
Find your carrier below
Every carrier uses its own code. Find yours in the list on this page and use the code printed there — a code from another carrier will be rejected or, worse, accepted and ignored.
Copy the code and put your Heyline number in it
Replace the placeholder with your own 10-digit Heyline number, no +1 and no dashes. Copy the whole string rather than tapping a link: iPhones refuse to dial a link containing * or #.
Dial it from the business phone itself
The code has to be dialed from the handset whose calls you want forwarded, not from another phone. You should get a short confirmation tone or message.
Turn your carrier voicemail off, then test it
Carrier voicemail answers first and would take the call before Heyline hears it. Turn it off, then call your business line from another phone and let it ring through.

VoIP or internet phone
Forwards unanswered calls.
How to set it up
Open your phone provider's app or admin site (RingCentral, Ooma, Google Voice, Grasshopper, Dialpad, 8x8, Vonage…) and find Call Handling or Call Forwarding. Set it to forward calls you don't answer — after about 15 to 20 seconds, or 3 to 4 rings — to your Heyline number. If your provider only offers one 'forward if no answer' rule, that's enough. Then turn your provider's voicemail off, or set it to pick up after Heyline, so she answers your missed calls.

Landline
Forwards busy and no-answer calls.
How to set it up
On many landlines you dial *90 (forward when busy) then *92 (forward when no answer) and enter your Heyline number when prompted. These codes vary by phone company — if they're rejected, call your provider and ask them to turn on 'Call Forward Busy / No Answer' to your Heyline number.

How do you set the forwarding up?
About five minutes, once, from the handset you want forwarded. You need your Heyline number, which arrives in the go-live wizard.
Find your carrier on this page
Verizon, AT&T, T-Mobile, Rogers, TELUS and Bell each get a block with their own code, undo code and warnings.
On Rogers, switch your voicemail off first
Rogers will not take the code while its voicemail is on (that is the only carrier here with the rule). On an internet line, turn your provider's voicemail off or set it to pick up after Heyline.
Copy the code, do not tap it
Every code holds a star or a hash, and an iPhone will not dial a link that holds either. Paste it instead.
Dial it from the line you want forwarded
A code only changes the handset it was dialed from. Dial it on a second phone and you have forwarded that one.
Ring your own line from another phone
Let it ring out without picking up. She should be talking to you within two rings — the only proof the code took.

Which calls roll over, and what does it cost?
Every code here is conditional. It fires on a condition and never on every call. Some networks add the handset being switched off or out of signal; two of the six bill forwarding as a charge of its own.
| Carrier | Calls that reach her | What the forwarding costs |
|---|---|---|
| Verizon | Busy, no answer. | Plan minutes. No separate charge. |
| AT&T | Busy, no answer, phone off. | Plan minutes. No separate charge. |
| T-Mobile | Busy, no answer, phone off. | Plan minutes. No separate charge. |
| Rogers | Busy, no answer. | Plan minutes — voicemail off first. |
| Bell | Busy, no answer, phone off. | About 25¢ CAD a minute if it is not on your plan. |
| TELUS | Busy, no answer, phone off. | About 50¢ CAD a minute if it is not on your plan. |
| VoIP or landline | Calls you do not answer. | Whatever your provider charges for call handling. |
Forwarding everything is not offered here: it would stop your own phone ringing. A forwarded call also spends Heyline minutes — pricing has the allowance on each plan.
What if you are on VoIP or a landline?
Then there is no star code to dial. Internet phone services — RingCentral, Ooma, Google Voice, Grasshopper, Dialpad, 8x8, Vonage and the rest — keep this setting in their own app or admin site, usually under call handling. You want the rule that fires on a call nobody answers, pointed at your Heyline number.
Give it three or four rings, roughly fifteen to twenty seconds, before it rolls over. Any quicker and she takes calls you would have reached in time. Much slower and the caller has already given up on you.
Then move your provider's own voicemail out of her way, or set it to pick up after her. On a business line you want the service that can book the job to get there first.
Older landlines carry the same two rules as separate phone-company features. If the codes your provider lists get refused, ring them and ask for call forward busy and call forward no answer, both aimed at your Heyline number.
The code did not take — what now?
Work down this list before you call anybody. The last two catch most people.
- You are on Rogers and its voicemail is still switched on. Rogers refuses the code until it is off. Turn it off and dial again.
- You dialed from a different handset. A forwarding code only ever changes the line it was dialed from.
- The number went in with a +1, a space or a dash. Carriers want the ten digits and nothing else.
- Wi-Fi Calling was running. TELUS asks for it off while the code goes in.
- You are on Rogers and the combined code was refused. Dial the two fallback codes in the Rogers block instead, one after the other.
- You are on an internet line or a landline, where there is no code to dial — the rule lives in your provider's app.
- You are simply not sure. There is one test: ring the business line from a phone that is not it, and wait for her.
What forwarding never does
Forwarding does not move your number. Heyline never touches your carrier account, never ports anything, and never hears a call you picked up yourself.
A forwarded caller stays with her. Heyline has no transfer, so nobody gets put through to your cell, and she will not text a soul. What comes back to you is an email recap and a line in your call log.
Card numbers are off limits as well. She stops a caller who begins reading one out.
And none of it is permanent. Dial your carrier's undo code and the arrangement is gone, with your missed calls landing in carrier voicemail again on the very next ring.
Frequently asked questions
What is conditional forwarding?
It is forwarding with a condition attached. Rather than sending every call somewhere else, your carrier passes one on only when your line is busy, when it rings out unanswered, or — on some networks — when the handset is switched off. Your own phone rings first every time, and a call you answer never leaves it.
Will forwarding cost extra on Bell or TELUS?
It can. Those two are the only carriers here that bill forwarding as a line of its own: Bell can charge about 25¢ CAD a minute, and TELUS about 50¢ CAD a minute, when it is not already included in your plan. Ask them before you dial. Verizon, AT&T, T-Mobile and Rogers use your plan minutes.
Why do I copy the code instead of tapping a link?
Because every forwarding code holds a star or a hash, and an iPhone refuses to dial a link that contains either. So the code comes to you ready to paste, with your ten-digit Heyline number already sitting inside it, and you drop it into your keypad yourself. One paste, any handset, nothing to mistype.
What if I use a VoIP line or a landline?
Then there is nothing to dial. Internet phone providers keep forwarding in their own app or admin site, under call handling: set the rule for calls you do not answer, and point it at your Heyline number. On a landline, your phone company can switch on forward-on-busy and forward-on-no-answer for you.
My carrier is not on the list — can I still forward?
Almost certainly. Conditional forwarding is an ordinary carrier feature, not a Heyline one. Search your provider's support site for forwarding when busy or unanswered, or ring them and ask them to aim it at your Heyline number. The carriers printed here are simply the ones we have cross-verified ourselves.
Does my carrier voicemail have to be off?
On Rogers, yes — the code will not take while Rogers voicemail is on. On Verizon, AT&T, T-Mobile, TELUS and Bell, no: the code sends a busy or unanswered call to your Heyline number before the mailbox can pick up, so leave your voicemail as it is. On a VoIP line, switch your provider's voicemail off or set it to answer after her.
