Asterisk Voicemail integration allows Home Assistant to view, listen to and delete voicemails from a Asterisk voicemail mailbox.
|
|
|
|
There are two components to the integration:
|
|
|
|
- A server that runs on the Asterisk PBX host and communicates over an open port.
|
|
- A client which can request inormation from the server.
|
|
|
|
Both parts are necessary for Asterisk voicemail integration.
|
|
|
|
The server installation is documented below. The client is [integrated inside Home Assistant](/components/asterisk_mbox)
|
|
|
|
<p class='note'>
|
|
Currently this module can only monitor a single Asterisk PBX mailbox.

### {% linkable_title Prerequisites %}
|
|
|
|
Before beginning make sure that you have the following:
|
|
|
|
- A functional Asterisk PBX setup which is using the default `voicemail` application.
|
|
- Both Home Assistant and Asterisk PBX running on the same LAN (or the same server).
|
|
- The Asterisk PBX server has Python 3.5 or newer installed.
|
|
- Administrator access on the Asterisk PBX (for python module installation).
|
|
- Account access to the `asterisk` user that runs the Asterisk PBX software.
|
|
|
|
### {% linkable_title Installation %}
|
|
|
|
1. Apply for a Google API key to enable speech-transcription services
|
|
|
|
2. Install the `asterisk_mbox_server` python module:
|
|
|
|
```bash
|
|
$ pip3 install asterisk_mbox_server
|
|
```
|
|
|
|
3. Create a configuration file for the server
|
|
|
|
As the `asterisk` user create an `asterisk_mbox.ini` file. You can place this in any directory you choose, but the recommended location is `/etc/asterisk/asterisk_mbox.ini`.
|
|
|
|
```ini
|
|
[default]
|
|
host = IP_ADDRESS
|
|
port = PORT
|
|
password = PASSWORD
|
|
mbox_path = PATH_TO_VOICEMAIL_FILES
|
|
cache_file = PATH_TO_CACHE_FILE
|
|
google_key = GOOGLE_API_KEY
|
|
```
|
|
|
|
- **host** (*Optional*): The IP address to listen on for client requests. This defaults to all IP addresses on the server. To listen only locally, choose `127.0.0.1`
|
|
- **port** (*Optional*): The port to listen on for client requests. Defaults to 12345.
|
|
- **password** (*Required*): A password shared between client and server. Use only alpha-numeric characters and spaces
|
|
- **mbox\_path** (*Required*): The path to the storage location of mailbox files. This is typically `/var/spool/asterisk/voicemail/default/<mailbox>/`
|
|
- **cache\_file** (*Required*): A fully-qualified path to a file thht can be written by the server containing transcriptions of voicemails. Example: `/var/spool/asterisk/transcription.cache`
|
|
- **google\_key** (*Required*): Your 40 characters Google API key.
|
|
|
|
Once complete, ensure this file is only accessible by the Asterisk user:
|
|
|
|
```bash
|
|
$ sudo chown asterisk:asterisk /etc/asterisk/asterisk_mbox.ini
|
|
$ sudo chmod 600 /etc/asterisk/asterisk_mbox.ini
|
|
```
|
|
4. Interactively start the server to verify it is functioning
|
|
|
|
```bash
|
|
$ sudo -u asterisk asterisk_mbox_server -v --cfg /etc/asterisk/asterisk_mbox.ini
|
|
```
|
|
|
|
Now complete the [Home Assistant configuration](/components/asterisk_mbox) and verify that Home Assistant can communicate with the server
|
|
|
|
You can use `Ctrl-c` to terminate the server when done testing
|
|
|
|
5. Configure the server to start automatically
|
|
|
|
Copy the following code into `/etc/systemd/system/asterisk_mbox.service`:
|
|
```ini
|
|
[Unit]
|
|
Description=Asterisk PBX voicemail server for Home Assistant
|
|
Wants=network.target
|
|
After=network.target
|
|
|
|
[Service]
|
|
Type=simple
|
|
User=asterisk
|
|
Group=asterisk
|
|
ExecStart=/usr/local/bin/asterisk_mbox_server -cfg /etc/asterisk/asterisk_mbox.ini
|
|
Restart=on-failure
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target
|
|
```
|
|
|
|
<p class='note'>
|
|
This assumes that your Asterisk PBX server is using `systemd` for init handling. If not, you will need to create the appropriate configuration files yourself.
