If you chose to **keep your existing business number** (Option B in [Connect your number](/phone-and-voice/connect-your-number)), you'll need to enable **Conditional Call Forward on No-Answer (CFNA)** with your carrier. This is a free feature included on virtually every business phone plan. CFNA tells your carrier: *"If a call to my number rings unanswered for X seconds, forward it to this other number."* In our case, that other number is your ServiceBooked number, which then runs the auto-text and AI Receptionist. ## Built-in wizard The fastest path: **Settings → Phone → Carrier forwarding wizard** in your dashboard. Pick your carrier and it generates the exact dial codes with your ServiceBooked number pre-filled. The codes below are reference for when you want to dial them manually or troubleshoot. ## Carrier codes Pick your carrier in the wizard and it fills in the right code with your ServiceBooked number baked in. The reference below is for dialling manually or troubleshooting. Dial the **enable** code once from your existing business handset — it sticks until you dial the cancel code. Examples below use `16135551234` as a stand-in for your ServiceBooked number (digits only, with the leading `1`). ### Bell / Virgin Mobile * **Enable:** `*92` + your ServiceBooked number — e.g. `*9216135551234` * **Cancel:** `#92#` If your line uses Visual Voicemail, you may need to disable it before CFNA will accept the change. ### Rogers / Fido / Chatr * **Enable:** `*72` + your ServiceBooked number — e.g. `*7216135551234` * **Cancel:** `*73` Rogers customers can also enable forwarding through the My Rogers app under **Voicemail → Call Forwarding → No Answer**. ### Telus / Koodo / Public Mobile * **Enable:** `*72` + your ServiceBooked number — e.g. `*7216135551234` * **Cancel:** `*73` ### US carriers (Verizon / AT\&T / T-Mobile) * **Enable:** `*72` + your ServiceBooked number — e.g. `*7216135551234` * **Cancel:** `*73` Most US carriers use `*72` to forward and `*73` to cancel. T-Mobile users may need to enable forwarding in the T-Mobile app first. ### UK carriers (EE / O2 / Vodafone / Three) * **Enable:** `**61*` + your ServiceBooked number + `#` — e.g. `**61*16135551234#` * **Cancel:** `##61#` UK carriers use MMI codes. After dialling, your phone should display a confirmation; if it doesn't, check your carrier's support page. ## Troubleshooting **The codes don't work.** Check that you dialled from the actual phone the number is associated with — not from a forwarded line. Some pre-paid plans don't include CFNA; you may need to call your carrier to enable it on your account first. **Calls are forwarding too quickly (don't ring my phone at all).** Your carrier's ring delay — how long your line rings before it forwards — is set too short. This is a carrier-side setting; contact your carrier to lengthen the no-answer timer (most default to around 20 seconds). **Calls aren't forwarding at all.** Confirm with `*#21#` or your carrier's status code that forwarding is actually active. Some carriers reset forwarding after a port-out or plan change. **International callers don't reach me.** A few carriers don't forward inbound international calls by default. Contact your carrier and ask them to enable "international call forwarding" on your account. ## Custom dial codes Some smaller carriers (regional CLECs, business-class fiber providers) use non-standard codes. The wizard has an **Other / not listed** option where you can type the carrier-specific enable/cancel codes — once saved, they're stored on your account so you don't have to remember them. If your carrier isn't listed and you're not sure, search "\[carrier name] conditional call forward no answer code" or call their business support line. ## Next: the auto-text With forwarding live, the next step is configuring what message gets sent when a call goes unanswered: The first message every missed caller receives. Get this right and you'll book more jobs.
