Forward Your Business Calls to InstantBook

To let InstantBook answer, qualify, and route your calls, forward your current business number to your InstantBook number. This lets customers keep calling the number they already know while InstantBook handles the intake behind the scenes.

[Your InstantBook Number]

Find this number inside your InstantBook Phone Number & Porting page.

Carrier steps can vary

The exact steps can vary depending on your phone provider. If one method does not work, check your carrier's call forwarding settings or contact their support.

Quick method

Try star-code forwarding first

For many major carriers, you can enable call forwarding by dialing *72 followed by your InstantBook number.

Example format

*72 [Your InstantBook Number]

Turn forwarding off

*73

Test before relying on it

Call your business number from another phone.

After forwarding is enabled, call your public business number from a different phone. Make sure the call reaches the InstantBook flow, voicemail, or routing path you expect.

Leave yourself a voicemail test if needed.
Confirm calls still reach the right place.
Save your provider's instructions in case you need to turn forwarding off.

Support note
