# Assigning phone numbers

![Telephony step in campaign wizard for assigning numbers.](https://mintcdn.com/callaro-docs/Rn-efrjnSIS1s0ID/images/campaigns/assign-numbers.png?fit=max\&auto=format\&n=Rn-efrjnSIS1s0ID\&q=85\&s=c348b71b8bbc4aa775e4676958e8850a)

# Assigning Phone Numbers to a Campaign

**There is no separate “launch checklist” page in the app** — see [Campaign launch checklist](https://help.callaro.ai/campaigns/campaign-launch-checklist.md) for the human checklist aligned to **Create campaign** and actions on **campaign detail**. **Assigning numbers** for new or edited bulk campaigns happens in the **Telephony** step of the campaign wizard, not on a standalone “assign numbers” screen.

Numbers affect **answer rates**, **trust**, and **carrier / reputation health** from the first dial. Deliberate telephony setup makes performance interpretable; accidental pools make every later diagnosis noisy.

**In the product**

* [Wizard Step 2: Telephony](https://help.callaro.ai/campaigns/wizard-step-2-telephony.md)
* [Spam-flagged numbers playbook](https://help.callaro.ai/phone-numbers/spam-flagged-numbers.md)

## Before you start

* Know **campaign geography** and **audience regions**.
* Numbers are **provisioned** in your workspace / telephony connection.
* You will **monitor health** during the pilot (answer rate, spam flags).
* Prefer a **small pool** first unless you already trust the numbers.

## Who should own this

1. **Sales Ops:** picks pool composition and monitors early metrics.
2. **SDR leadership:** aligns caller ID strategy with audience expectations.
3. **Admin / telephony owner:** provisioning, caps, escalations.

## Assign numbers step by step (wizard)

1. Open **Create campaign**, or **Edit** a draft. You can also start from a **template** or **clone** an existing campaign when the product offers those options on the first screen.
2. Move to the **Telephony** step (second step in the six-step flow).
3. Choose the **telephony connection** if the screen asks — numbers may belong to different providers; in-app copy notes that **provider comes from the number** you select.
4. Pick **Primary / From** and add one or more numbers to the **campaign pool**. You must have **at least one** number in the pool before **Next** is available.
5. Read any **capacity** or pool hints on the step; after launch, pair those with **dispatch health** and [Troubleshooting: not dialing](https://help.callaro.ai/campaigns/wizard-troubleshooting-not-dialing.md).
6. Complete **Audience → Schedule → Outcomes → Review**, save, then **Launch** from **campaign detail** when ready.

## What the important decisions mean

1. **Single vs. pool:** One number simplifies a **pilot**; a **small pool** spreads load once behavior is trusted.
2. **Local presence:** Regional alignment can help pickup; misaligned IDs can hurt trust.
3. **Labels / naming:** Operational clarity when multiple business lines share a tenant.
4. **Health:** Remove or rest **flagged** numbers before scaling (see [Spam-flagged numbers](https://help.callaro.ai/phone-numbers/spam-flagged-numbers.md)).
5. **Rotation discipline:** Add numbers **intentionally**; measure outcome impact instead of assuming more IDs always help.

## What good looks like

* Assigned numbers match **audience geography** and **brand** expectations.
* The team can explain **why** those numbers were chosen.
* Early metrics are **stable enough** to iterate script and schedule.
* **Dispatch health** does not show persistent **capacity** or **connection** surprises tied to the pool.

## Common mistakes and troubleshooting

* **Next** stays disabled on Telephony — add **at least one** number to the pool.
* **No numbers listed** — provision or import numbers for the connection first ([Adding phone numbers](https://help.callaro.ai/phone-numbers/adding-phone-numbers.md)).
* Poor answer rates — check **region fit** and **schedule** before rewriting the script.
* Spam flags — shrink pool to healthy IDs and follow the spam playbook.
* Unclear ownership — fix **labels** and documentation before scaling spend.

## Final checklist

* **Telephony** step shows the intended **primary from** and **pool**.
* **Pilot** size matches telephony risk tolerance.
* **Health owner** named for the first live hours.
* **Launch** still uses the actions on **campaign detail** after you save the wizard.
