### 4. Enable HTTP API Access

Activate "Packet parser camera access" in the device settings. This allows TapHome to retrieve video and status information from the doorbell.

### 5. Create HTTP User Account

Generate an HTTP user with credentials (username and password) that will be used in TapHome as access credentials for authentication.

### 7. Configure User Phone Number

Set the user's phone number using the following format:

**sip:nnn@CoreIpAddress**

Where:
- `nnn` is the SIP extension number
- `CoreIpAddress` is your TapHome Core unit IP address

### 10. Set Quick Dial Button

Configure the ring button with the following settings:

- Set button to call a predefined user
- Set button function **during call to hang up**

### 11. Establish Static IP Configuration

Configure either:
- MAC-based permanent IP reservation in your router, OR
- Direct static IP assignment on the device

This prevents device address changes that could disrupt connectivity.

Example static IP: 192.168.100.170
