A simple asterisk configuration with a single digit dialplans for a toddler to learn how to use an analogue phone.
Watch a demo of the phone on youtube:

Build with:
$ sudo build.sh
The build script builds, configures, and starts asterisk.
This asterisk deployment is meant to run on an environment that doesn't support docker. It can be developed in an lxd container.
When the phone is picked up, the PAP2 will dial the number 1. The dialplan
will answer when any number is dialed. The Paw Patrol input is played, then
the dial plan goes into an infinite loop: it waits for input. If the input is
in 1 through 6 (inclusive), a pup catch phrase is played, then it goes back to
waiting for input. If the input is unexpected, then go back to the waiting for
input state.
To configure a Linksys PAP2 to connect to Asterisk:
| Configuration Page | Key | Value | Source of value in Asterisk |
|---|---|---|---|
| Line 1 | SIP Port | 5060 | (Default value) |
| User ID | 6001 | /etc/asterisk/pjsip.conf: Group name and 6001.username=6001 |
|
| Password | unsecurepassword |
/etc/asterisk/pjsip.conf: 6001.password=unsecurepassword |
|
| Proxy | asterisk |
The hostname of the machine running asterisk | |
| Dial Plan | P0<:1> |
Auto dials the extension 1 |
Connect to the Asterisk console with
sudo asterisk -r
Wave files must be mono and sampled at 8Hz. The wav with a 16 bit sample width sounds much better than a wave with an 8 bit sample width. To take any wave and convert it to mono and resample it, execute:
sox $INPUT --channels 1 --bits 16 --rate 8000 $OUTPUT
