# Routing filters

Routing filters split a call flow into paths, so each call goes to the destination that fits when it arrives or where it comes from. This page covers the Time of Day, Day of Week and Caller ID Prefix filters.

> **Warning:** The Time of Day, Day of Week and Caller ID Prefix filters are available on Marketing and Agency plans only.

## Route by time of day

> **Note:** To route calls based on day of week instead, see: [Route by day of week](https://help.nimbata.com/call-handling/routing-filters#route-by-day-of-week).

The **Time of Day** filter lets you route calls to different destinations depending on when they arrive. For example, business-hours calls to your sales team and after-hours calls to voicemail or an on-call mobile.

1. **Open the Call Flow Builder**

   - Go to [Call handling > Call Flows](https://app.nimbata.com/call-handling/call-flows).
   - Click **+ Create**.

2. **Add the Time of Day filter**

   - Click the **+** button on the canvas.
   - Select **Time of Day** from the Filters menu.

5. **Configure time ranges and destinations**

   - On each Time of Day block, set the start and end time for that branch (for example, 09:00 to 18:00 for business hours, 18:00 to 09:00 for after hours).
   - On each Dial action, select the destination number for that time window.

   ![On each Dial action, select the destination number for that time window.](https://help.nimbata.com/_astro/04-image_1iv2pdi.W-e_cDUI_Z1aXB6z.webp)

🎉 Done. Calls will now be forwarded to the correct destination based on the time they arrive.

## Route by caller location

The **Caller ID Prefix** filter reads the first digits of an incoming caller's number (country code or area code). Then, it routes the call to the destination you assign to that prefix.

This powers **Geo-routing**: the ability to send callers to a local office, regional team, or franchise branch based purely on where they're calling from.

**Common use cases include:**

- Routing Chicago-area calls (312) to a Midwest sales team.
- Sending UK callers (+44) to an international support line.
- Blocking entire country codes from reaching your numbers at all.

### How geo-routing with Caller ID Prefix works

When a call arrives, Nimbata checks the caller's number against the prefixes you've configured. If there's a match, the call follows the path you defined for that prefix. Any number that doesn't match a configured prefix follows the default "remaining" path, which you also define.

> **Tip:** You can configure as many prefix routes as you need. Prefixes can also be used to route anonymous calls, send certain regions straight to voicemail, or hang up immediately.

### Set up geo-routing

1. **Open the Call Flow Builder**

   - Go to [Call handling > Call Flows](https://app.nimbata.com/call-handling/call-flows).
   - Click **+ Create** to create a new call flow.

2. **Add the Caller ID Prefix filter**

   - Click the **+** button on the canvas.
   - Select **Caller ID Prefix** from the Filters menu.

   ![Select Caller ID Prefix from the Filters menu.](https://help.nimbata.com/_astro/01-image_1tgrs3b.CsRH3UIj_Z1nYAuk.webp)

3. **Enter the prefixes you want to isolate and define what happens to them**

   - Type the country codes or area codes you want to handle differently into the prefix field.
   - Click the **+** below that branch and select the routing action for those callers (for example, **Hang Up**, **Voicemail**, or **Dial** to a specific destination).

   - Repeat steps 3 and 4 for each additional region or country you want to handle differently.
   - Connect each new prefix branch to its appropriate routing action.
