Common questions

Can I keep my business number?

Yes. You don't move your number anywhere. Lightspire gives you a second Australian number, and you divert your existing number to it. Your customers keep ringing the number they know.

How it works

  1. You get your Lightspire number in the dashboard. See Get your Australian number.
  2. On the phone your customers ring, you dial a short code that diverts calls to your Lightspire number.
  3. Your agent answers. Turn the divert off with another code whenever you like.

You choose what gets diverted: every call, or only the calls you don't answer. Most owners start with the calls they don't answer, so their phone rings first.

The codes

Put your Lightspire number in place of {your number}, with no spaces, starting with 0. Your Phone number page shows the same codes with your number already in them.

Phone Every call Calls you don't answer Turn it off
Telstra mobile **21*{your number}*11# **61*{your number}*11# ##21# or ##61#
Telstra home phone (nbn) *21{your number}# *61{your number}# #21# or #61#
Optus mobile **21*{your number}# **61*{your number}*20# ##002# (all)
Vodafone mobile **21*{your number}# **61*{your number}# ##002# (all)

Telstra mobiles divert a call you haven't answered after 15 seconds. On Optus, the 20 is how many seconds it rings first.

Optus doesn't publish divert codes for its home phone, so ask Optus to forward it to your Lightspire number. On a business phone system, set forwarding in the system itself or ask your phone provider. Vodafone prepaid can't forward to another number; it needs a plan.

The full steps are in Divert your calls to Lightspire and Divert a landline.

What diverting costs

That's between you and your carrier. Telstra says forwarding is included on plans with unlimited calls, and Vodafone says forwarding within Australia is free on a plan. On anything else, check with your carrier.

If you stop using Lightspire

Dial the turn-off code on your phone and calls ring through to you as before. Your own number never left you.

Your Lightspire number is different: it's yours while you subscribe. When your subscription ends, it's released after a short grace period and may go to someone else. If you want to keep it, email support@lightspire.ai before you cancel.
