Call forwarding setup

Forward the calls you miss to your Zio number. Your own phone still rings. Forwarding every call is an option, not the setup to start with.

AT&T wireless

Use this if the business number is an AT&T cell phone. AT&T's wireless help does not give a star code. You turn forwarding on from the phone itself. Do not dial *67. That blocks caller ID.

Recommended

Forward only the calls you miss

Your phone still rings. Zio gets the call when you do not answer, when you are already on a call, or when the phone is off or out of signal.

  1. Open the Phone app.
  2. Open Settings, then Call forwarding. On many AT&T phones the path is Phone, Settings, Calling accounts, your SIM, Call forwarding. The names differ by phone. If you do not see these labels, open AT&T's call-forwarding help for your phone model instead of dialing a code.
  3. Turn on When unanswered. Enter your Zio number, then tap Turn on.
  4. Turn on When busy and enter your Zio number.
  5. If you see When unreachable, turn that on with your Zio number too.
Forward every call instead

Forward every call

Your phone will not ring. Callers go straight to Zio.

  1. Open the same Call forwarding screen, choose Always forward, enter your Zio number, and tap Turn on.

Turn it off

  1. Open the same Call forwarding screen, choose the option you turned on, and tap Turn off.

AT&T says you can change wireless call forwarding only from the phone, not from the website.

AT&T says forwarded wireless calls are billed for the length of the call and can include long-distance or roaming charges.

If this line is an AT&T home phone or an AT&T business phone, use those sections instead. The cell-phone menus do not apply.

Codes can differ by plan. After you save this, call your business number from a different phone and confirm Zio answers. If it does not, turn forwarding off and contact the phone company before you try another code.

Verizon wireless

Use this if the business number is a Verizon cell phone. From the phone, dial the code and the 10-digit Zio number together.

Recommended

Forward only when you do not answer or the line is busy

Verizon calls this Conditional Call Forwarding, or No Answer/Busy Transfer. Your phone rings first. If you do not answer, or you are already on a call, the caller goes to Zio instead of voicemail.

Dial this, then Call

*71 then the 10-digit Zio number

  1. Dial *71, then the 10-digit Zio number, then Call. The number will appear here once it is assigned.
  2. Wait for the confirmation beeps. Verizon says the call then ends on its own.
  3. If *71 does not work, contact Verizon. Do not switch to *90 or *92. Those are not the Verizon wireless codes.
Forward every call instead

Forward every call

Verizon calls this Immediate Call Forwarding. Your phone will not ring.

Dial this, then Call

*72 then the 10-digit Zio number

  1. Dial *72, then the 10-digit Zio number, then Call.

Turn it off

Dial this, then Call

*73

  1. Verizon says *73 turns off call forwarding, including the no-answer/busy option. Wait for the confirmation tone.

Verizon's examples write the code with dashes, such as *71-999-555-4567. Dial the star code and the 10 digits. You do not dial a dash.

Forwarding to international numbers is not available.

Codes can differ by plan. After you save this, call your business number from a different phone and confirm Zio answers. If it does not, turn forwarding off and contact the phone company before you try another code.

T-Mobile

Dial these from the T-Mobile phone. The number includes a leading 1. Use two stars. A single *67 blocks caller ID and does not forward the call.

Recommended

Forward only the calls you miss

Set all three. Your phone still rings for calls you can answer. Zio gets the ones you miss, the ones that arrive while you are on a call, and the ones that arrive when the phone is off or has no signal.

When you do not answer

**61*1XXXXXXXXXX#

When the line is busy

**67*1XXXXXXXXXX#

When the phone is off or has no signal

**62*1XXXXXXXXXX#

  1. Open the Phone app, dial one code, and press Call. Wait for the confirmation, then dial the next code.
  2. Each code needs 1 plus the 10-digit Zio number. It will fill in once your number is assigned.
  3. T-Mobile lets you set how long the phone rings before an unanswered call forwards. The basic no-answer code above uses T-Mobile's default. To pick the delay, dial **61* then 1 and the 10-digit number, then ** and the seconds, then #. T-Mobile's example is **61*18056377243**10# for 10 seconds. Allowed delays are 5, 10, 15, 20, 25, or 30 seconds.

T-Mobile says you cannot forward to international numbers, and the destination has to be 10 or 11 digits.

Codes can differ by plan. After you save this, call your business number from a different phone and confirm Zio answers. If it does not, turn forwarding off and contact the phone company before you try another code.

Landline or internet phone

Home phones and internet phones do not share one code. Use the company that sends your phone bill. If it is not listed, call them and ask for no-answer and busy forwarding to your Zio number. Do not try a code from a different company.

Recommended

The recommended setup rings your phone first and sends Zio only the calls you do not answer or cannot take.

AT&T local home phone

AT&T does not publish a star code for no-answer or busy forwarding on a traditional home phone. Call 800.288.2020 and ask them to turn on Call Forwarding - Don't Answer and Call Forwarding - Busy Line to your Zio number.

  1. Tell them the forward-to number is your Zio number.

Forward every call, if you want that instead

Turn forward-all off

*73

  1. Pick up and dial *72 or 72#.
  2. When you hear the dial tone, dial 1 plus the 10-digit Zio number if the Zio number is long distance. AT&T's chart says a local number may need fewer digits.
  3. Wait for the confirmation tone. AT&T then calls the Zio number. Someone, or Zio, has to answer or the feature will not turn on.

AT&T Phone, U-verse, or the AT&T business phone in AT&T's call-forwarding article

These codes are for AT&T Phone and the business line covered by AT&T article KM1181691. They are not the cell-phone steps and not the traditional home-phone steps.

*92 then the 10-digit Zio number, then #

No answer off

Busy on

*90 then the 10-digit Zio number, then #

Verizon Fios or Verizon home phone

Verizon publishes more than one no-answer code, and the page says the feature may not be on every line. Use only the code that matches the feature on your bill. If you hear an error, stop and ask Verizon which one you have.

Busy line on, if that feature is on your line

*90

Busy line off

*91

Busy / don't answer on, if that feature is on your line

*92

Busy / don't answer off

*93

Variable busy / don't answer on, if that feature is on your line

*42

Variable busy / don't answer off

*43

  1. After the on code, dial your Zio number when the recording or the second dial tone asks for the forward-to number.
  2. On a traditional Verizon home phone, forward-all (*72) is a different feature: the destination has to answer before it turns on.

Forward every call on Verizon Fios or a Verizon home phone

Verizon's Fios guide says this overrides other forwarding, and your home phone will not ring. Use it only if you want every call to leave the line.

Turn this forward-all off

*73

  1. Pick up and dial *72.
  2. Wait for the second dial tone.
  3. Dial your Zio number.
  4. Wait for the confirmation tone. On a traditional Verizon home phone, the Zio number has to answer or you must call it again within two minutes.

Another internet phone or VoIP provider

  1. Sign in to the provider's admin page.
  2. Find Call forwarding, No answer, or Busy. Enter your Zio number.
  3. Leave forward-all off unless you want every call to skip your phone.
  4. If you do not see those settings, contact the provider and ask them to forward unanswered and busy calls. Do not dial a star code unless their own instructions tell you the exact code.

Turn it off

Use the off code paired with the feature you turned on. If the phone company set it up for you, call them and ask them to remove forwarding to your Zio number.

A separate AT&T business voice product publishes different busy codes (*62 on, *63 off) in AT&T's feature access code PDF. *67* on that PDF only checks busy-forward status. If you use that product and these codes do not match your guide, call AT&T instead of trying *67.

Codes can differ by plan. After you save this, call your business number from a different phone and confirm Zio answers. If it does not, turn forwarding off and contact the phone company before you try another code.

RingCentral or a similar business system

Business phone systems usually have a missed-call setting. Use that. Forward-all sends every caller away, including the calls you could have answered.

Recommended

RingCentral: forward only when nobody answers

  1. In the RingCentral desktop or web app, open Settings, then Incoming call rules.
  2. In the section for your work day, work hours, or after hours, find If no one answers.
  3. Choose Forward the call and enter your Zio number.
  4. Save.
  5. RingCentral's menus change. If you do not see If no one answers, follow RingCentral's own call-handling article or ask your admin. Do not guess a star code.

Vonage Business Cloud

  1. Sign in to the Admin Portal.
  2. Open Phone System, then Extensions. Hover over the extension and click the pencil icon.
  3. Open Call Forwarding and turn Forward Calls on. Choose Send to an extension or phone number and enter your Zio number.
  4. Vonage describes this as how calls are handled when you are away from the phone. It does not publish a separate no-answer star code. If you need the desk phone to ring first, ask Vonage what the ring time is before the call forwards, then place a test call.
  5. Turn it off by switching Forward Calls off. Unanswered calls then follow your voicemail settings.

Vonage Enterprise

  1. Sign in to the Vonage Enterprise Portal.
  2. Open Voice Settings, then Call Forwarding.
  3. Turn on Busy and No Answer. Enter your Zio number. Leave Always off unless you want every call forwarded.
  4. You can also set Not Reachable and the number of rings.
  5. Turn those options off to stop forwarding. Vonage says the settings may be hidden until an admin allows them.

A different business phone system

  1. Sign in to the admin portal and look for missed calls, no answer, or busy. Enter your Zio number.
  2. Leave any Forward all or Always setting off.
  3. If the screen does not match this, contact that provider. Do not reuse a cell-phone star code.
Forward every call instead

RingCentral: forward every call

RingCentral's Forward all calls feature overrides normal call handling. Leave it off unless you want every call to go to Zio.

  1. In the RingCentral app, open your profile, then Incoming call rules.
  2. Turn on Forward all calls, choose Forward the call, and enter your Zio number.
  3. A banner in the app reminds you that calls are being forwarded. Use Turn off in that banner when you want your phones to ring again.

Turn it off

  1. To stop missed-call forwarding, open If no one answers and choose voicemail, or remove the Zio number, then save.
  2. If you turned on Forward all calls, turn that toggle off.

Codes can differ by plan. After you save this, call your business number from a different phone and confirm Zio answers. If it does not, turn forwarding off and contact the phone company before you try another code.

Google Voice

Do not forward a Google Voice number to Zio. Google's own help says forwarding a Google Voice number to an automated system is unsupported.

Recommended

If customers call a cell phone, landline, or business system, forward that number with the matching section above.

If the only number customers call is a Google Voice number, contact Google. Linking a number and waiting for a verification code is not a supported way to send those calls to an automated receptionist.

Turn it off

Nothing to turn off here, because this path is not a supported setup.

If Google Voice is already sending calls somewhere unexpected, sign in at voice.google.com and review Call forwarding under Settings, then Calls.

Place a test call

  1. 1. Turn on the no-answer or busy forwarding for your phone company.
  2. 2. Call your business number from a different phone.
  3. 3. Let it ring. Zio should answer with the greeting you set.
  4. 4. If the call never reaches Zio, turn forwarding off and check the code before you try a different one.
