+# Setting Up the sip_notifier Service
+
+The add-on is running, but you need to add the service to Home Assistant manually.
+
+## Add to your `configuration.yaml`
+
+Add this to `/config/configuration.yaml`:
+
+```yaml
+rest_command:
+  sip_notification:
+    url: "http://088d3b92-sip-notifier:8099/send_notification"
+    method: POST
+    content_type: "application/json"
+    payload: >
+      {
+        "destination": "{{ destination }}",
+        {% if audio_url is defined %}"audio_url": "{{ audio_url }}",{% endif %}
+        {% if message is defined %}"message": "{{ message }}",{% endif %}
+        "duration": {{ duration | default(30) }}
+      }
+```
+
+## Restart Home Assistant
+
+Settings → System → Restart
+
+## Usage
+
+After restart, use the service:
+
+```yaml
+service: rest_command.sip_notification
+data:
+  destination: "+15551234567"
+  message: "Hello from Home Assistant!"
+  duration: 20
+```
+
+Or with audio URL:
+
+```yaml
+service: rest_command.sip_notification
+data:
+  destination: "+15551234567"
+  audio_url: "https://example.com/alert.mp3"
+  duration: 30
+```
+
+## Alternative: Create a Script
+
+If you prefer a more friendly name, add this to `configuration.yaml`:
+
+```yaml
+script:
+  sip_voice_notification:
+    alias: "Send Voice Notification"
+    description: "Place a SIP call and play audio"
+    fields:
+      destination:
+        description: "Phone number (+15551234567)"
+        example: "+15551234567"
+        required: true
+      audio_url:
+        description: "HTTP(S) URL to audio file"
+        example: "https://example.com/alert.mp3"
+        required: false
+      message:
+        description: "Text message for TTS"
+        example: "Emergency alert"
+        required: false
+      duration:
+        description: "Call duration in seconds"
+        example: 30
+        default: 30
+    sequence:
+      - service: rest_command.sip_notification
+        data:
+          destination: "{{ destination }}"
+          audio_url: "{{ audio_url | default('') }}"
+          message: "{{ message | default('') }}"
+          duration: "{{ duration | default(30) }}"
+```
+
+Then use:
+
+```yaml
+service: script.sip_voice_notification
+data:
+  destination: "+15551234567"
+  message: "This is a test"
+```
+
+## Example Automation
+
+```yaml
+automation:
+  - alias: "Water Leak Alert"
+    trigger:
+      platform: state
+      entity_id: binary_sensor.water_leak
+      to: "on"
+    action:
+      - service: rest_command.sip_notification
+        data:
+          destination: "+15551234567"
+          message: "EMERGENCY! Water leak detected!"
+          duration: 40
+```
+
+## Troubleshooting
+
+### Service not found after restart
+
+1. Check configuration.yaml syntax
+2. Check Home Assistant logs for errors
+3. Verify add-on is running (Settings → Add-ons)
+
+### Call fails
+
+Check add-on logs:
+Settings → Add-ons → SIP Voice Notifier → Log
+
+Look for SIP connection errors or audio conversion issues.
