Forward missed calls on a Spark home or business phone.

Set it up in a few taps

• Sign in to MySpark.
• Open Products & services, then your fibre or wireless landline.
• Open Call diversion and enter the number to forward to.

Where these codes come from.

These are Spark home or business phone’s own codes, from its help page (Spark: fibre and wireless call features). We checked them on 21 October 2026.

Why forwarding fails, and the fix.

• Voicemail took the slot back. Voicemail uses the same “no answer” setting, and some phone updates restore it. Dial the check code; if it shows your voicemail number, dial the forwarding code again.
• Live Voicemail on iPhone, or Take a Message on Pixel, answers first. Turn it off in the Phone settings.
• Wi-Fi Calling is on. Some networks reject codes over Wi-Fi. Switch Wi-Fi Calling off, dial the code, then switch it back on.
• Prepay or pay as you go. Many prepay plans block forwarding or only allow voicemail. The network page above says which.
• The number is in the wrong format. Use the format your network asks for, with no spaces.
• Dual SIM. Codes apply to the SIM that dials them, so dial from your business SIM.
• The ring time is too short. Under 15 seconds you lose calls you were about to pick up. 20 seconds suits most people.

Test it in two minutes.

Ask someone to ring your number three times. Each call should reach the number you forwarded to:

• Let the first call ring out. That tests “no answer”.
• Press decline on the second. That tests “busy”.
• Turn on flight mode for the third. That tests “phone off”.

Forward them to a receptionist, not a voicemail box.

Most people forward missed calls to voicemail, and most callers hang up on it. Aroha gives you a number to forward to. Its receptionist answers in your business’s name, books the job or takes the details, and texts you a summary. Your phone still rings first, and the cancel code switches it off any time.

Get a free number: Aroha answers up to 60 minutes of calls in your first 14 days, then about 10 calls a month for free. No card. The setup screen shows these codes with your number already filled in.

Questions

How do I turn off call forwarding on Spark home or business phone?

Open the same menu you used to set it up and switch call forwarding off.

How do I check whether call forwarding is on?

Open your phone’s call forwarding settings; it shows the number calls go to.

Why do missed calls still go to voicemail on Spark home or business phone?

Voicemail uses the same “no answer” setting, so the last one set wins. Dial the forwarding code again, and on iPhone turn off Live Voicemail.
