# FritzAB2Matrix

__FritzAB2Matrix__ reads out the answering machine (_TAM_) of a _Fritz!Box_ in your LAN and posts the messages into a private chat in the __matrix__ network. While you could let your _Fritz!Box_ send the messages by mail - unencrypted of course - the matrix chat is __e2e encrypted__. Which kindly acknowledges the privacy of any caller that leaves a message for you.

Uses the python based cmd-line-tool [matrix-commander](https://github.com/8go/matrix-commander) so the matrix-commander.py in this repo is just a copy of that file to ease testing.
## Features
 * Since _v0.1.1_ __Multitam__ is integrated so that you can check multiple answering machines __and__ post the messages to different matrix rooms. (Use _FRITZ\_TAM_ variable in .env file)
 * Set _FRITZ\_CALL\_WATCH_=True if you want to receive a message everytime you miss a call.
## Installation
If you like to test this repository you are recommended to use one of the following two options.
### Necessary preparations for both cases
 * Create a new user (e.g. "fritzab") in your _Fritz!Box_. **Don't use your default admin account!**
   * This user needs only the privileges regarding voice messages and to read from box's storage.
   * As you only need to access the _FRITZ/voicebox/rec/_ path you should remove the right to read and write everything and add only this path and only with reading privilege.
     * __Beware!__ If you use a USB device as expanded storage for your _Fritz!Box_ and allowed the TAM to use it for storing more messages you will need another path (e.g. _Storage-01/FRITZ/voicebox/rec/_). You also have to add the FRITZ_VOICEBOX_PATH variable in your _.env_ file (see below) according to that difference.
 * You have to activate __Call Monitoring__ on your _Fritz!Box_ by using one of the connected phones and call `#96*5*`.
   * Call monitoring watches the box and the __FritzAB2Matrix__ is triggered every time a call disconnects.
   * If you cannot activate Call Monitoring the only way to use __FritzAB2MAtrix__  will be to have a cron job call it regularly. 

### virtualenv
 * Create a new folder wherever you like in your home directory.
   * Make it a virtual environment by `python3 -m venv <new folder>` and `source <new folder>/bin/activate`.
   * `cd <new folder>`
 * Clone the repo.
 * Inside the repo run `pip install --upgrade pip && pip install -r requirements.txt`
 * Create an `.env` file with your favourite editor:
 ```
FRITZ_USERNAME="fritzab2matrix"
FRITZ_PASSWORD="S0meSecretPa5sw02d"
FRITZ_IP="192.168.178.1" 
FRITZ_TMP="/tmp" 
# FRITZ_VOICEBOX_PATH="fritz.nas/FRITZ/voicebox" 
FRITZ_TAM='{"0" : "!roomhash1:matrix.org", "1" : "!roomhash2:matrix.org"}' 
FRITZ_CALL_WATCH=False
 ```
__.env__

 *
    * Adjust it according to your data.
 * For matrix-commander.py to work you need to run it manually the first time by `python3 matrix-commander` and follow the emerging dialog by putting in your matrix account data.
 * After all that you can finally run `./fritzab2matrix.py` and your TAM messages should be posted in the chosen matrix chat.
### Docker
Provided you have docker and docker-compose installed on your system:
 * Clone the repo and cd into it.
 * Create the above mentioned `.env` file.
 * Run `docker-compose -f docker/docker-compose.yml build` and watch docker work some minutes.
 * After that slightly edit the `docker-compose.yml`
   * and add
```
  
   volumes:
      - ../.:/app
```
 *
   * so that your repo is used as volume for the `/app` folder. So everything you change in the repo's folder will affect the docker container.
 * For __matrix-commander.py__ to work you need to run it manually the first time by `python3 matrix-commander` and follow the emerging dialog by putting in your matrix account data.
   * With docker that means that you need to open an _interactive shell_ in the running container (`docker-compose -f docker/docker-compose.yml exec app /bin/bash` and run this command there.
   * Follow the appearing dialog and input your matrix account data.
 * After all that the running docker container should watch your box and your TAM messages should be posted in the chosen matrix chat.
