How to forward your business line (without porting your number)

The biggest objection we hear is not price. It is “I am not moving my number.”

You do not have to. Nothing about adding an AI receptionist requires porting, and we would talk you out of it if you asked. Your number stays exactly where it is, with the carrier you already pay. All you change is where unanswered calls land.

Here is every way to do it, in order of how much control it gives you.

Option 1 — Unconditional forwarding (the ten-second version)

This sends every call to the AI line the moment it is switched on.

• Turn on: dial *72, then the AI number, then call
• Turn off: dial *73

That is it. Most owners do this at closing time and reverse it in the morning for the first week, until they trust it enough to leave it on.

Works on: almost every US landline, VoIP line and mobile carrier.

Option 2 — Busy and no-answer forwarding (what you actually want)

This is the setting that recovers the most money, and it is the one nobody knows exists. It forwards a call only when your line is busy or nobody picks up. Your office answers everything it can; the AI catches the overflow.

• Forward when busy: *90 + number
• Forward when unanswered: *92 + number
• Cancel busy forwarding: *91
• Cancel no-answer forwarding: *93

Set both and you have continuous coverage with zero change to how your team works. The phone rings on the desk exactly as it does today. It just stops falling on the floor.

Codes vary slightly by carrier. If *90 does nothing, search “conditional call forwarding” plus your carrier name — every provider supports it, they just bury it in the portal.

Option 3 — Ring count on no-answer forwarding

Most carriers let you set how many rings pass before the forward triggers. Four rings is the sweet spot: long enough for your CSR to grab it, short enough that the caller does not start wondering.

On VoIP systems (RingCentral, Ooma, Vonage, Grasshopper, 8x8) this is a dropdown in the admin panel, usually under Call Handling → Rules. On a mobile carrier it is often fixed at three or four rings and cannot be changed.

Option 4 — Time-based routing in your VoIP portal

If you are already on a hosted phone system, skip the star codes entirely. Every one of them supports a schedule:

1. Open Call Handling, Auto-Receptionist or Answering Rules
2. Create a rule for after business hours
3. Set the destination to External number and paste the AI line
4. Add a second rule for holidays, which is the one everyone forgets

This is the cleanest setup because it needs no human to remember anything at 5pm on a Friday.

Common snags, and the fix

“It rings once then drops.” Your carrier is rejecting the forward. Nine times out of ten the AI number was entered with a 1 when the carrier wants ten digits, or without a 1 when it wants eleven. Try the other format.

“Callers hear my voicemail instead.” Your voicemail is answering before the forward triggers. Lower the voicemail delay, or raise the forwarding ring count so the forward wins the race.

“My mobile forwards but my office line does not.” They are separate services with separate settings, even on one bill. Configure each.

“I use a call-tracking number for ads.” Point the tracking number at the AI line rather than at your main line. You keep attribution and the call still gets answered.

How to test it in two minutes

1. Switch the forwarding on.
2. Call your main number from your mobile.
3. Book a fake appointment. Give a real-sounding address in your service area.
4. Check that the confirmation text arrives and the job appears on the calendar.
5. Delete the test job.

Do this once before you rely on it. Do it again the first Monday after any phone system change, because carrier settings silently reset more often than they should.

Undoing everything

*73 and *93. Two dials, and you are exactly back to where you started, with the same number, the same carrier and the same contract.

That is the reason we never ask anyone to port. A setup you can reverse in ten seconds is a setup you can try tonight without a meeting about it.
