Forwarding does not change your number and does not port anything. It tells your carrier's network where to send a call under a condition you choose: every call, or only the ones you do not answer, or only when your line is busy. It is switched on with a short code dialed from the phone itself, and switched off the same way, usually in under a minute.

Two ways to forward

  • Forward every call (unconditional). Your phone stops ringing; the other number takes everything. Use it when you want the interruptions gone.
  • Forward when unanswered or busy (conditional). Your phone rings first, exactly as today. Only when you are on another call or do not pick up within a few rings does the call roll to the other number instead of voicemail. Use it when you like answering yourself and want a net under the calls you miss.

In the codes below, [number] is the ten-digit destination number with no spaces, for example **21*2125550123#. Dial it, press Call, and wait for the confirmation tone or message before hanging up. Every code was read from the carrier's own support page on 2026-09-02; carriers change these occasionally, so if your carrier's page disagrees with this one, the carrier wins, and we would like to know: hello@ansurra.com.

Forwarding questions.

Should I forward every call or only unanswered ones?

If you want your day back, forward everything. If you like answering when you can, use the unanswered / busy codes: your phone rings first and only rolls over when you do not pick up. Both are reversible with one more code.

Does forwarding change my number?

No. Your number stays with your carrier and on your phone. Forwarding only tells the network where to send calls you do not take. Nothing is ported.

Does it cost anything?

On most US plans forwarding itself is free and forwarded minutes count like any other call. Some Canadian plans (Bell Mobility, TELUS) bill forwarding as an add-on or per minute; the carrier notes above say which.

How many rings before an unanswered call forwards?

Usually four to five, set by the carrier. T-Mobile lets you change the delay in the app; on most others it is fixed.

The code did nothing. What now?

Wait for the confirmation tone or message before hanging up; some phones need you to press Call after the code. If it still fails, the feature may be disabled on your plan: the carrier app or a support call switches it on.

Can I forward to a receptionist service?

Yes, that is the common use. You forward to the number the service gives you; with Ansurra that number is bound to your own AI receptionist and you keep your existing line.

Forward the calls you miss to a receptionist that answers.

Ansurra picks up 24/7, books on your calendar and emails you every detail. Two free test calls, then plans from $29 a month.
