# Call routing

A call flow's routing option decides which destination numbers a call rings. This page shows how to ring several numbers at once, ring them in order until someone answers, or split calls between them by percentage.

## Ring several numbers at once

> **Note:** There is no call flow template for Multiple routing, so build it with the steps below. Sequential and Weighted routing have templates: see [Start from a template](https://help.nimbata.com/call-handling/call-routing#start-from-a-template).

The **Multiple** routing option rings several destination numbers at the same time. The first agent to pick up takes the call. This reduces wait times, distributes load automatically, and ensures callers reach a live person without being placed in a queue.

1. **Open the Call Flow Builder**

   - Go to [Call handling > Call Flows](https://app.nimbata.com/call-handling/call-flows).
   - Click **Create** (or open an existing call flow to edit it).

2. **Add the Multiple routing action**

   - Click the **+** button on the canvas.
   - Select **Multiple** from the Routing Options menu.

   ![Select Multiple from the Routing Options menu.](https://help.nimbata.com/_astro/01-image_soagmj.1tYCwWrB_1JwVcO.webp)

3. **Add destination numbers**

   - Click **Select Destinations**.
   - Add as many destination numbers as needed.

4. **Assign the call flow to tracking numbers**

   - Go to [Tracking > Numbers](https://app.nimbata.com/tracking/numbers).
   - Assign the new call flow to the relevant tracking numbers.

🎉 Done. Every call coming through those tracking numbers will now ring all destinations simultaneously until one answers.

## Ring numbers in order

> **Note:** To use the templated setup instead, see: [Sequential Call Flow template](https://help.nimbata.com/call-handling/call-routing#sequential-call-flow-template).

**Sequential call routing** directs incoming calls to your team members one by one, in a defined order. If the first person doesn't answer, the call automatically moves to the next person on the list, and so on, until someone picks up or the flow reaches its end (for example, voicemail).

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 Sequential routing action**

   - Click the **+** button on the canvas.
   - Select **Sequential** from the Routing Options menu.

   ![Select Sequential from the Routing Options menu.](https://help.nimbata.com/_astro/01-image_1cux57h.MWfrSJHj_ZQq2gB.webp)

3. **Add destination numbers**

   - Click **Select Destinations**.
   - Add at least 2 destination numbers.

   ![Add at least 2 destination numbers.](https://help.nimbata.com/_astro/02-image_yba10r.Chd83J8P_Zu3zlC.webp)

4. **Configure ring time and sticky destinations**

   - Adjust the **seconds to ring** per destination (default: 25 seconds).
   - Optionally enable **Sticky Destinations**: when active, a returning caller is routed to the same agent who answered their last call.
   - If **Sticky Destinations** are enabled, set how many days back the system should look.

5. **Assign the call flow to tracking numbers**

   - Go to [Tracking > Numbers](https://app.nimbata.com/tracking/numbers).
   - Assign the call flow to the relevant tracking numbers.

🎉 Done. Calls will now ring each destination in order until someone answers.

## Send unanswered calls onward

When a call goes unanswered at the first destination, **Sequential routing** automatically moves it to the next number on your list. Each destination rings for a defined number of seconds before the call advances, reducing missed calls without requiring any manual intervention.

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, or click an existing one to edit it.

2. **Switch the Dial action to Sequential**

   - Click the **three-dot menu** on the top-right of the **Dial** block.
   - Select **Change to Sequential**.

   ![Select Change to Sequential.](https://help.nimbata.com/_astro/01-image_14q14rh.gTPmkar2_Z1zNylE.webp)

3. **Add your destination numbers**

   Click **Select Destinations** and add all the numbers you want calls to try in sequence.

   ![Click Select Destinations and add all the numbers you want calls to try in sequence.](https://help.nimbata.com/_astro/02-image_ga0b65.DQjpKJLt_Z1jvIB9.webp)

4. **Set the ring time per destination**

   - Choose how many seconds the call rings at each destination before advancing to the next.
   - Optionally rename the call flow for easy identification.

5. **Assign the call flow to tracking numbers**

   - Go to [Tracking > Numbers](https://app.nimbata.com/tracking/numbers).
   - Assign the call flow to the relevant tracking numbers.

🎉 Done. Unanswered calls will now automatically try the next destination in your sequence.

## Split calls by percentage

> **Note:** To use the templated setup instead, see: [Weighted Call Flow template](https://help.nimbata.com/call-handling/call-routing#weighted-call-flow-template).

**Weighted call routing** distributes incoming calls across destination numbers according to percentages you define. Use it to match call volume to agent capacity, route by skill level, or split traffic between departments.

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 Weighted routing action**

   - Click the **+** button on the canvas.
   - Select **Weighted** from the Routing Options menu.

   ![Select Weighted from the Routing Options menu.](https://help.nimbata.com/_astro/01-screenshot-2026-05-28-152251_17717oe.CliN042d_ZosGUs.webp)

3. **Add destination numbers**

   - Click **Select Destinations**.
   - Add the numbers you want calls distributed to.

4. **Set the distribution percentages**

   Adjust the percentage slider for each destination so the total equals 100%.

5. **Assign the call flow to tracking numbers**

   - Go to [Tracking > Numbers](https://app.nimbata.com/tracking/numbers).
   - Assign the call flow to the relevant tracking numbers.
