# How to divert a business landline or VoIP number

The short answer

On most UK landlines you dial *61* then the number and # to divert calls not answered within 15 seconds, *67* for when you're on another call, or *21* for every call. Cancel with # and the same code, for example #61#. Some providers make you add call diversion to the line first, and the diverted part of each call is usually charged at your normal rates. On a VoIP phone system, set a forwarding rule in its app or online portal.

## BT business phone lines

| What it does | Dial

| Divert calls not answered within 15 seconds | *61*[number]#

| Divert calls if the phone is engaged | *67*[number]#

| Divert all calls | *21*[number]#

| Cancel a divert | #61# (or 67, 21)

| Check a divert is on | *#61# (or 67, 21)

Call diversion is a paid add-on on BT business lines. The diverted part of the call is charged at BT's standard rates. You'll hear an intermittent dial tone while a divert is on.

## BT Digital Voice

| What it does | Dial

| Divert calls not answered within 15 seconds | *61*[number]#

| Divert calls when your phone is engaged | *67*[number]#

| Divert all calls | *21*[number]#

| Check where calls are diverted | *#61# (or 67, 21)

Dial the codes on a phone plugged into the BT Hub, or use the Calling Features menu on a Digital Voice handset. Call Diversion is free on Digital Voice. Calls diverted to BT mobiles, BT Home Phones and Digital Voice lines are free; other numbers are charged at the standard rate or come out of your call package.

## Vodafone Business landlines

| What it does | Dial

| Divert calls not answered within 15 seconds | *61*[number]

| Divert calls when you're on another call | *67*[number]

| Divert all calls | *21*[number]

| Turn a divert off | #61# (or #67#, #21#)

| Check a divert is on | *#61# (or *#67#, *#21#)

Vodafone's example is *21*07123456789 to divert all calls to a mobile. On premium business plans, Vodafone offers Smart Divert instead.

## Virgin Media Business phone line over broadband

| What it does | Dial

| Divert calls not answered | *61*[number]#

| Divert calls when your line is busy | *67*[number]#

| Divert all calls | *21*[number]#

| Turn off | #61#, #67# or #21#

Call Virgin Media Business to switch Call Divert on the first time; after that you manage it yourself. Include the area code in the number. Calls diverted to another number are charged as set out in your tariff. The unanswered divert also kicks in if your router is off or offline.

## O2 Business analogue lines (customer-controlled divert)

| What it does | Dial

| Divert calls not answered | *61*[number]#

| Divert calls when busy | *67*[number]#

| Divert all calls | *21*[number]#

| Cancel a divert | #61# (or 67, 21)

O2 Business sells customer-controlled diverts as a monthly add-on, and also charges for the diverted part of each call. Most analogue line diverts are live within 24 hours of ordering, and some types take up to three working days. You can only set it from a handset on that line.

## On a VoIP or cloud phone system

Most VoIP and cloud phone systems handle forwarding in their own app or online portal rather than with star codes.

- 1Sign in to your phone system's app or admin portal.
- 2Find call forwarding or call handling rules for your number or extension.
- 3Add a rule to forward to an external number: when unanswered, when busy, out of hours, or all three.
- 4Enter the number we give you and save.
- 5Ring your business number from a mobile and let it ring out to check it works.

## What it costs

- On most landlines, you pay for the diverted part of the call, from your line to the number you divert to, at your normal rates or from your call package.
- Some providers charge for the divert feature itself. BT business lines and O2 Business analogue lines sell it as an add-on; BT Digital Voice includes it free.
- On VoIP systems, forwarding to an outside number is normally charged as an outgoing call from your account. Ask your provider.

Landlines and VoIP divert questions

## Asked and answered.

Can I divert my Landlines and VoIP number to an AI receptionist?+

Yes. Divert to the number we set up for your receptionist, ideally only when you don't answer, when you're busy and when your phone is off, so you still take the calls you can.

Does diverting calls cost anything on Landlines and VoIP?+

On most landlines, you pay for the diverted part of the call, from your line to the number you divert to, at your normal rates or from your call package. Some providers charge for the divert feature itself. BT business lines and O2 Business analogue lines sell it as an add-on; BT Digital Voice includes it free. On VoIP systems, forwarding to an outside number is normally charged as an outgoing call from your account. Ask your provider.

How do I check the divert is working?+

Ring your number from another phone and let it ring out. You should hear your AI receptionist answer, and get the email with the caller's details a moment after you hang up.
