What is call routing?

Call routing decides where each call to your business number goes: which phones ring, in what order, and what happens if nobody answers. Start by forwarding every call to your mobile. Add a menu and extensions later on the same number.

Forward to your mobile

Every call rings your mobile. Unanswered calls go to business voicemail.

Add a menu & extensions

“Press 1 for Service.” Each extension rings its own phones.

Set after-hours rules

A closed-hours greeting, with calls sent to voicemail or an on-call mobile.

Give each extension its own phones, with separate after‑hours rules.

A sample setup for a three-person plumbing business. Switch to After hours to see the same number when you’re closed.

Extensions are options inside your phone system. Callers dial your business number, then press an option or enter a person’s extension, such as 101.

Send one extension to your own AI agent & ring people on the others.

Sales goes to your own intake agent from Vapi or another provider. Support rings Sarah’s mobile. The same agent can also cover after hours.

Learn how AI agent connections and after-hours routing work.

Add a greeting menu & extensions when you need them.

Type your greeting and choose a voice, or record it yourself. Give each option an extension with its own phones and voicemail recipients.

Ring phones in order or at the same time.

In order, each phone rings in turn until someone answers. At the same time, every phone rings and the first person to accept takes the call.

Ring the mobiles and landlines your team already has, with no per-user fees.

First to accept takes the call

Unanswered calls go to business voicemail.

When the ring list runs out, the caller hears your business voicemail greeting. The message is recorded, transcribed, summarized, and emailed to the people you choose for that extension.

With call announce, whoever picks up presses 1 to accept, so a personal voicemail can’t take the call. Numberline moves on to the next phone, then to business voicemail.

For an answering service, choose direct connect, and the call is handed off the moment they answer.

Set business hours & separate after‑hours rules.

Outside business hours, callers hear a closed-hours greeting. Calls go to business voicemail, an on-call mobile, or your answering provider.

Set up call forwarding in three steps.

1

Choose a greeting & menu.

Type or record your greeting. Skip the menu if every call should ring the same phones.

2

Pick the phones for each extension.

Add mobiles, an existing business phone, or a landline. Nobody needs to install anything to answer.

3

Set business hours & voicemail.

Choose who gets each extension’s voicemails and where after-hours calls go. Change it any time on the same number.

Frequently asked questions

Can I forward all calls to my mobile?
Yes. Callers hear your greeting, then your mobile rings with the business number as caller ID. If you don’t answer, the call goes to business voicemail.
Do callers have to use a menu?
A menu is optional. Without one, every call goes straight to the phones you chose, and you can add menu options later.
Can an extension ring more than one phone?
Yes. Each extension rings its own list of mobiles or landlines, one after another or all at once. Callers always dial your business number to reach it.
What happens when nobody answers?
The call goes to business voicemail. The message is recorded, transcribed, summarized, and emailed to the people you choose. With call announce, a personal voicemail can’t take the call. Numberline tries the next phone, then business voicemail.
Can my own AI agent answer one extension while a person answers another?
Yes. Connect your AI agent from Vapi or another provider and assign it to Sales. Support keeps ringing the phones you chose.
Can I keep my existing business number?
Yes, if it is eligible. Porting is free and we handle it. Your current service keeps working until the move completes. You can also start on a new number and keep both. See the porting guide.
