To install these, simply run the following 8 | from your command line. 9 | ```` 10 | npm install 11 | ```` 12 | 13 | # Asterisk configuration 14 | In order to use ARI applications, you will need to enable Asterisk's HTTP server, as well as enabling ARI. A simple 15 | http.conf file you can use would be the following 16 | ```` 17 | [general] 18 | enabled = yes 19 | bindaddr = 0.0.0.0 20 | bindport = 8088 21 | ```` 22 | A simple ari.conf file you can use would be the following 23 | ```` 24 | [general] 25 | enabled = yes 26 | allowed_origins = * 27 | [asterisk] 28 | type = user 29 | password = asterisk 30 | ```` 31 | Note that the code in the hide 'n' seek application has the built-in assumption that they can use ARI as user "asterisk" 32 | with password "asterisk". If you wish to use a different username and password combination, you will need to set ari.conf 33 | to use your desired username and password, and alter the ````client.connect()``` line in client.js to use the appropriate 34 | HTTP URI, username and password you would like. 35 | 36 | Once you have ARI configured, you will need to provide a way for incoming calls to reach your ARI application. The 37 | application name is "hide-n-seek". It is suggested that you provide two entry points to the application, one for hiders 38 | and one for seekers. The following is a suggested dialplan: 39 | ```` 40 | [default] 41 | exten => 500,1,NoOp() 42 | same => n,Stasis(hide-n-seek,hider) 43 | same => n,Hangup() 44 | 45 | exten => 501,1,NoOp() 46 | same => n,Stasis(hide-n-seek,seeker) 47 | same => n,Hangup() 48 | ```` 49 | With this setup, callers who dial 500 will be hiders, and callers who dial 501 will be seekers. 50 | 51 | # Running the application 52 | Once you have Asterisk configured, and you have the prerequisites installed, running the app simply requires you to start 53 | Asterisk, and then run the following with HOST and PORT set to your Asterisk HOST and PORT 54 | ```` 55 | export HOST=http://localhost 56 | export PORT=8088 57 | node app.js 58 | ```` 59 | from your checkout of this repo. The client will connect to Asterisk and will be ready to accept incoming calls. 60 | 61 | # Viewing the game from a browser 62 | Point your browser at http://localhost:3000 63 | 64 | Enjoy! 65 | -------------------------------------------------------------------------------- /app.js: -------------------------------------------------------------------------------- 1 | 'use strict';
