Forward missed AT&T calls to an AI receptionist

AT&T uses the GSM-style forwarding codes: your phone rings first, and calls you miss roll to your AI receptionist instead of voicemail. Setup is one dialed code and takes about thirty seconds.

dial this exactlythen press call

**61*<number>#

Missed calls only (recommended). Your phone rings first. Use the 10-digit number. Replace <number>with your AI receptionist's 10-digit number.

Every call, phone never rings**21*<number>#

Set it up

1Open the phone keypad and dial **61* followed by the 10-digit forwarding number, then #, then press call.
2Wait for the confirmation message on screen.
3Call your number from another phone and let it ring out. The AI should answer after several rings.

The quirks nobody tells you

We run these setups on live business lines. These are the failure modes we actually hit.

Cricket works the same way

Cricket runs on AT&T's network and takes the same GSM codes. Some Cricket prepaid plans gate forwarding; if the code errors, ask Cricket support to enable it.

Test with a ring-out, not a glance

The on-screen confirmation only proves the network stored the rule. Place a real call, let it ring without touching the phone, and confirm the AI answers. That is the only test that counts.

Turning it off

Turn off missed-call forwarding##61#

Takes effect immediately. Knowing the off switch is five seconds away makes the on switch easier to try.

A forwarding code needs something worth forwarding to

Corex's AI receptionist answers the AT&T calls you miss, around the clock. It answers questions about your business, books the job, takes the message, and puts urgent callers through to you. Live in minutes with a local number, from $149 a month.

Common questions

Do these codes work on AT&T prepaid?

Usually yes. If a code errors out, AT&T support (611) can enable conditional forwarding on the line.

Can I forward only after-hours calls?

Not with dial codes; the carrier rule is always on. The usual pattern is to leave missed-call forwarding on around the clock, since the AI only handles what you do not answer anyway.
