## Symptom

The phone rings, often at night, with calls from short numbers such as 100 or 1000, or from an IP address. When you answer, nobody is there.

## Likely cause

These calls come from SIP scanners: programs that probe the internet for phones and adapters with weak security. They don't come through the PBX: they reach the phone directly, because the phone accepts direct IP calls by default.

## Fix

Set the phone to accept calls only from its own SIP server:

1. Type the phone's IP address into a web browser (press **OK** on the phone to see it) and sign in. The default username and password are both `admin`.
2. Go to **Features** › **General Information** and scroll down.
3. Turn **Allow IP Call** off.
4. Turn **Accept SIP Trust Server Only** on.
5. Click **Confirm**.

The phone still makes and receives normal calls through the PBX. [Auto-provisioned](https://kb.voipcloud.online/au/phones-and-apps/yealink/auto-provisioning/) phones get both settings from the PBX, so they shouldn't need this change.

## Also check

- Change the phone's web interface password from the default `admin`. On an auto-provisioned phone, set it with **Replace default Yealink web portal passwords (recommended)** in the SIP device's **Yealink settings**.
- Check your network setup against [Network requirements](https://kb.voipcloud.online/au/getting-started/network-requirements/).

## When to contact support

If ghost calls continue after these changes, [open a support ticket](https://kb.voipcloud.online/au/support/support-tickets/) with the times of the calls and the numbers shown.
