Will my phone still ring first on AT&T or Cricket?

Yes. These steps set up conditional forwarding: your phone rings first, and only calls you don't answer, or that arrive while you are busy, are sent on. They do not forward every call.

Where do I get the number to forward to?

When you start a DispatchAI trial you are given your own DispatchAI number. Put that number wherever the steps show [your DispatchAI number].

It didn't work. What should I check?

Codes are carrier- and plan-dependent and can fail silently when mistyped. Re-enter the code, test with a real call, and if it still doesn't take, ask your carrier to enable call forwarding on your line.

Forward Only Missed Calls on AT&T or Cricket

Step-by-step: send only unanswered and busy calls to your answering service on AT&T or Cricket, keep your own phone ringing first, and check it worked.

What this does

On AT&T or Cricket, these steps send only the calls you don't answer to your answering service. Your phone rings first and your business number does not change. Replace [your DispatchAI number] with the number you are given when you start a DispatchAI trial.

Steps

On iPhone, turn off Live Voicemail first: Settings → Apps → Phone → Live Voicemail. Apple says it stops carrier no-answer forwarding from working, and iOS updates can switch it back on.
Open your phone's dialer.
For calls you don't answer, dial: **61*[your DispatchAI number]*11*20# then press call. (The 20 is how many seconds your phone rings first — you can use 5 to 30.)
For calls that come in while you're already on the phone, dial: **67*[your DispatchAI number]# then press call.
You should see a short confirmation message on screen after each one.
Check it took: dial *#61# and press call — the screen should show [your DispatchAI number] as where unanswered calls go. If it shows voicemail or another number, dial ##61#, then set it again.

To turn it off

Dial ##61# to turn off no-answer forwarding, and ##67# for busy forwarding.

Codes depend on your carrier and plan. If something doesn't take, your carrier's support line can set it up in a couple of minutes. See the call forwarding overview for the other carriers.
