Softphone

You can use a softphone app to connect to Asterisk from your phone.

Here are some recommended apps:

Linphone

PUSH

To improve battery life you can use a PUSH message to wake up and register the softphone app if it supports it. You can send PUSH messages trough the Home Assisant companion app. Here is how to do it.

caution

Make sure your extension has quality=yes set, otherwise Asterisk thinks the extension is already online.

First Home Assistant needs to know when you are getting called. This can be done with the Asterisk integration or with a webhook in the dialplan like this example:

extensions.conf
exten => 8003,1,Set(CURL_RESULT=${SHELL(curl -X POST http://localhost:8123/api/webhook/push_sip)%7D)
exten => 8003,n,Wait(4)
exten => 8003,n,Dial(SIP/8003,30,rt)

Then you can make a automation to send the message to the softphone app.

tip

You can find the intent_class_name with a app called Shortcut Maker.

Linphone example:

Automation
- alias: Send push to activate app
  initial_state: 'on'
  trigger:
    - platform: webhook
      webhook_id: "push_sip" 
  action:
  - service: !secret notify_ha_fabio
    data:
      message: command_activity
      data:
        channel: com.basip.app
        tag: android.intent.action.MAIN
        intent_class_name: org.linphone.CallActivity
        priority: high
        ttl: 0
