# kids_phone Raspberry Pi project for a SIP or VoIP phone for children.

## Prerequisites

### Software - linphone - linphone python wrapper - python GPIO

### Hardware - USB audio device with mic and phone plug - buttons (tbd.)

Install linphone and python wrappers for the raspi: ` sudo apt-get install linphone-nogtk wget http://linphone.org/releases/linphone-python-raspberry/linphone4raspberry-3.9.1-cp27-none-any.whl sudo pip install linphone4raspberry-3.9.1-cp27-none-any.whl Install socket_client_server sudo pip install socket_client_server`

To register the linphone client on a SIP service run the linphone command line tool: ` #> linphonec linphone> register sip:<username>@<SIP_domain> sip:<SIP_domain> <PASSWORD> This will create an rc file /home/pi/.linphonerc` which will be used a standard configuration file for __kids_phone__.

## Python GPIO modules ` sudo apt-get install python-dev`

## Configuration Webserver ` sudo apt-get install python3-pip sudo pip3 install django pydbus sudo apt-get install git sudo apt-get install gunicorn3 sudo apt-get install nginx sudo apt-get install policykit-1`

I follow [the advise from gunicorn's documentation](http://gunicorn-docs.readthedocs.io/en/19.1.1/deploy.html) and use nginx as nginx as a proxy.

## Access point for initial setup

See [SETTING UP A RASPBERRY PI AS AN ACCESS POINT IN A STANDALONE NETWORK (NAT)](https://www.raspberrypi.org/documentation/configuration/wireless/access-point.md) ` sudo apt-get install dnsmasq hostapdsudo`

## Make kids phone a daemon
