**Dial tone access** (also called DISA) lets you call your PBX from any phone, enter a PIN code, and then dial out as if you were in the office. The person you call sees your business number.

It's useful when you only have a personal or borrowed phone but need to call a customer from your company number.

## Add it to your call flow

1. Drag **Dial tone access** from the **Accept, make and divert calls** group onto the canvas and click the gear icon.
2. Enter a **Name** and a **PIN code**.
3. Choose the **Caller ID** for outgoing calls. To limit how many calls can use it at once, choose a **SIP trunk call plan (optional)** and set the **Number of channels**.
4. Click **Save**, connect an [Inbound number](https://kb.voipcloud.online/au/pbx/receive-calls/inbound-number/) to it, and click **Apply configuration**.

To use it, call that number, enter the PIN code, then dial the number you want to call.

## Settings

| Setting | What it does |
| --- | --- |
| Name | Label on the canvas. |
| PIN code | Callers must enter this before they can dial out. |
| Caller ID | The number people see when you call them through this object. Only your purchased numbers (not toll-free or shared cost). The empty option is **Keep originator's caller ID**: the called person sees the caller's own number. |
| SIP trunk call plan (optional) | Rates used for calls through this object. By default the **Primary account** call plan is used. |
| Number of channels | How many calls can go through this object at the same time. Available only after you choose a **SIP trunk call plan (optional)**. |

**Warning:** Anyone who knows the PIN can make calls charged to your account. Use a long PIN, don't share it, and put **Dial tone access** on a number that isn't published.
