How to forward your business calls to an AI agent
You can keep the number your customers already know. Set your phone line to pass calls to your REENG agent, either always or only when you can't pick up.
Four steps
Find your agent's number
In your dashboard, open Phone Number and copy your agent's number in full, including the country code (for example +1…).
Check with your carrier first
Ask whether your line can forward to an international number and what each forwarded minute costs. Prepaid lines often can't.
Dial the code
From the phone on your business line, dial one of the codes below with your agent's number in place of NUMBER, press call, wait for the confirmation tone or message, then hang up.
Test it
Call your business number from a different phone. Your agent should answer, and the call will show up in your call log.
The codes
These are the standard GSM codes that most mobile networks follow. Not every network supports all of them or uses the same ones, so treat them as a starting point and confirm with your carrier.
| What you want | Dial | What happens |
|---|---|---|
| Forward every call | **21*NUMBER# | Every call goes to your agent. Use it when you want the agent as your full-time receptionist. |
| Forward when you're busy | **67*NUMBER# | Calls go to the agent only when your line is engaged. |
| Forward when you don't answer | **61*NUMBER# | Calls go to the agent after your phone has rung for a while. |
| Forward when you're unreachable | **62*NUMBER# | Calls go to the agent when your phone is off or out of coverage. |
| Check forwarding | *#21# | Shows whether all-call forwarding is on and where it goes. |
| Cancel all forwarding | ##002# | Switches every kind of forwarding off. |
Most businesses start with "when you don't answer" and "when you're busy", then switch to "every call" once they trust the agent.
Questions about forwarding
Will my callers dial a different number?
No. They keep calling your existing business number. Your carrier sends the call on to your agent's number, and the agent answers.
Does forwarding cost anything?
Your agent's number may be outside Nigeria. If it is, your carrier treats forwarded calls as international calls and may charge you for them. Ask your carrier for the rate before you switch forwarding on, and whether your line allows forwarding to another country at all.
What if the codes don't work on my line?
Some prepaid lines and carriers don't allow forwarding, or use different codes. Your REENG dashboard's Phone Number page shows the codes for your carrier, and your carrier's support can switch forwarding on for you.
How do I stop forwarding?
Dial the cancel code (##002# on most networks) and wait for the confirmation. Your phone rings normally again straight away.
