# Phone Line

> Production number, usage, and escalation for inbound answer and live transfer.

**Phone Line** is where inbound lands once Mixr assigns your number — usage visibility and the human escalation target for live transfer.

Open: [mixr.network/agents/voice/agent?section=line](https://www.mixr.network/agents/voice/agent?section=line)

Agents sections: [Voice](/product/agents/voice) · [Desk Chat](/product/agents/desk-chat) · **Phone Line**

## Settings

| Setting               | Function                                     |
| --------------------- | -------------------------------------------- |
| **Number / usage**    | Production inbound endpoint after assignment |
| **Escalation number** | Required before enabling **live transfer**   |

## Operating notes

* Numbers are assigned by Mixr after [setup](/product/voice-desk/setup); the active line appears here
* Enable **live transfer** under [Automations](/product/voice-desk/automations) only after escalation is set
* Outbound reminder calls use the Voice agent and plan minutes; they are scheduled under [Reminders](/product/voice-desk/scheduler) and reviewed in [Recents](/product/voice-desk/desk)
* Persona, knowledge, and call tools are configured under [Voice](/product/agents/voice)
