Forward unanswered calls from your cell phone to your Pine Mountain Voice AI number in just a few minutes.
Tap your carrier below for step-by-step instructions. You'll be dialing a short code from your phone's keypad — it takes about 30 seconds.
Go to your phone's dialer (the keypad you use to make calls).
Type the code below, replacing the placeholder with your 10-digit Pine Mountain Voice AI number:
For example: *71 5551234567
Tap the call button and wait 2–3 seconds for a confirmation tone or message.
Your phone will ring normally when a call comes in. If you don't answer, are on another call, or your phone is off, the call forwards to your Pine Mountain Voice AI number automatically.
Go to your phone's dialer (the keypad you use to make calls).
T-Mobile uses separate codes for each scenario. Dial each one, replacing the placeholder with your 10-digit Pine Mountain Voice AI number, and press Call after each:
Forward when No Answer:
Forward when Busy:
Forward when Unreachable (phone off / no signal):
After pressing Call for each code, wait for a confirmation tone or a message on your screen (e.g., "Registration was successful"). Then hang up and dial the next code.
All three scenarios are now covered. Calls will forward to your Pine Mountain Voice AI number whenever you can't pick up.
Go to your phone's dialer (the keypad you use to make calls).
AT&T supports a single code that activates forwarding for all three scenarios (no answer, busy, and unreachable) at once:
Press Call and wait for a confirmation message.
You should see a message like "Registration was successful" on your screen or hear a confirmation tone. If you get an error, see the individual codes below.
Your phone will ring first on every call. Only unanswered, busy, or unreachable calls go to your Pine Mountain Voice AI number.
Go to your phone's dialer (the keypad you use to make calls).

How to disable it:
On older iOS versions the path may be Settings → Phone → Live Voicemail. This applies to all carriers — Verizon, T-Mobile, AT&T, and Xfinity Mobile.
These features can silently block or intercept calls before forwarding activates:
Each major carrier has its own call-screening app that runs on the network level, separate from your phone's built-in settings. These can silently intercept or reroute calls to VoIP numbers like your Pine Mountain Voice AI number.
Before setting up forwarding, call your Pine Mountain Voice AI number directly from another phone. If the AI agent answers, the number is working and you can proceed with setup. If the call fails or doesn't connect, the issue is on the Pine Mountain Voice AI side — contact support before setting up forwarding.
