Call forwarding: how to set it up and keep calls moving

How call forwarding works

Your existing number receives the call, and a routing rule sends it to a destination number. That destination might be another phone, a team queue or an answering service. Forwarding moves the call; what happens next depends on whoever or whatever answers.

This can let you keep the number customers already know while changing who answers it. You normally configure the rule with the service that currently receives your calls. Buying another answering service does not automatically change that rule.

Forwarding is also separate from a phone menu or IVR, which asks the caller to choose an action, and call screening, which helps decide whether to accept a call.

Choose the forwarding rule your business needs

These options are not available on every plan. A mobile carrier may group busy and no-answer forwarding together. A business phone system may offer schedules and queues instead. Ask the current line provider which conditions, ring delays and destination restrictions it supports.

How to set up call forwarding

On iPhone

Apple documents the path as Settings → Apps → Phone → Call Forwarding. Enable it, select the line if prompted, and enter the destination under Forward To. Availability depends on the network and carrier. If the option is missing, use your carrier's instructions rather than assuming the phone is faulty. Apple's setup instructions ↗

With a carrier code

Codes vary by carrier. For example, Verizon's mobile instructions use *72 + the destination number for immediate forwarding, *71 + the destination number for conditional forwarding, and *73 to switch forwarding off. Confirm the current instructions for your exact service before dialing. These are Verizon examples, not universal codes. Verizon's forwarding instructions ↗

On Android or a business phone system

Use the current provider's device guide or phone-system admin interface. T-Mobile directs users to device-specific calling instructions. For a cloud phone system, look for inbound call handling, business hours, routing or overflow settings. Confirm whether you are editing one extension or the public business number; changing one does not necessarily change the other.

1. Record the existing rule and voicemail destination so you can restore them.
2. Confirm the new destination can receive a call directly.
3. Configure one routing rule and save it.
4. Call the public number from a separate line.
5. Check both the successful route and the failure route before relying on it.

A five-call test before you rely on forwarding

Use these as acceptance checks. A saved setting alone does not establish that callers reach the right destination.

• Normal call: call while the business line is available. Check which device rings first and whether the intended greeting plays.
• Unanswered call: let the original line ring out. Confirm the destination answers before the wrong voicemail takes over.
• Busy call: occupy the main line and place another call. Check the effect of call waiting or queue settings.
• Unavailable destination: make the receiving team unavailable. Confirm there is a useful message or fallback.
• Return to normal: disable the rule and call again. Confirm you know how to restore normal routing.

If an answering service transfers calls back to your team, test that separately. Sending a call back to the public number that forwards to the service can create a loop. Agree on a separate transfer destination or another supported routing arrangement.

Call forwarding not working? Check these first

The original phone still rings

You may have enabled conditional forwarding. Test what happens when the call is actually unanswered or busy, then check the rule type.

The wrong voicemail answers

Two timers may be competing. Ask the provider about the original line's voicemail delay and the forwarding delay, then test the complete route.

Calls go in circles

Check whether the destination forwards back to the original number. Remove the circular route and retest from a separate line.

Only some calls fail

Check caller-specific rules, business hours, concurrent-call limits and the destination's own blocking settings.

The call arrives, but the caller's number is wrong

Ask both services what caller ID they pass through. Do not assume the destination receives the original caller's number.

Check costs and limits on both sides

Account for the original line and the answering destination separately. Verizon notes that forwarded calls can use plan minutes and that some older plans may charge a forwarding fee. Its mobile forwarding does not forward SMS. Other carriers and business systems have their own terms.

Before committing, ask whether forwarded minutes, simultaneous calls, transfers and after-hours routing create charges. Confirm any destination-number restrictions and whether your existing SMS service stays separate.

Forwarding to a service also does not establish a booking integration. If the destination must create appointments, verify the exact action in your existing calendar or industry software. The AI answering-service comparison separates documented tasks, software fit and pricing uncertainty.

How to turn off call forwarding

Use the same carrier or phone-system controls that own the active rule. On an iPhone with the documented forwarding control, return to Settings → Apps → Phone → Call Forwarding and disable it for the intended line. For Verizon mobile, its published instructions use *73 to switch forwarding off. That code is carrier-specific, not a universal reset.

After disabling the rule, call the public number from another line. Check the normal ring path and voicemail. If a business system, another extension or the destination has its own forwarding rule, changing the mobile control may not remove that separate route.

Call forwarding versus call transfer

Forwarding redirects an incoming call according to the line's rule. A transfer moves a conversation that has already been answered. Use the transfer guide for warm and cold handoffs, and the routing guide when deciding which destination should be tried first.

Call forwarding and voicemail

Check which mailbox answers at each stage: the original line, the forwarded destination and any backup. A no-answer forwarding timer can compete with a voicemail timer. Confirm the supported settings with the line provider, then let a test call run through the entire route.

If callers should leave a request, use an accurate voicemail greeting and a monitored callback process. If too many calls reach the wrong mailbox, follow the missed-call diagnostic route before buying another service.

Common call forwarding questions

Do I have to port my number?

Forwarding and porting are different. Forwarding routes calls while the number remains with its current provider. Porting moves the number to another provider. Confirm your current service supports the intended forwarding destination.

Can I forward only after hours?

A phone system with schedule-based routing may support this. A simple mobile forwarding switch may require manual changes. Check the exact service and include holidays and time zones in your test.

Does forwarding answer calls for me?

It sends them somewhere else. A person, voicemail, queue or answering service at that destination must still handle the caller.
