Тестируем ARI Websocket

 yum install nodejs npm --enablerepo=epel

 npm install -g wscat

 npm install -g ws

# wscat -c ws://echo.websocket.org
connected (press CTRL+C to quit)
>

Подключимся к Asterisk при помощи wscat

 wscat -c "ws://localhost:8088/ari/events?api_key=test:test_password&app=hello-world"

[root@localhost ~]# wscat -c "ws://localhost:8088/ari/events?api_key=test:test_password&app=hello-world"
connected (press CTRL+C to quit)

Инициируем вызов через созданный контекст

    -- Executing [1776@from-test:1] NoOp("SIP/1000-0000023e", "") in new stack
    -- Executing [1776@from-test:2] Answer("SIP/1000-0000023e", "") in new stack
    -- Executing [1776@from-test:3] Stasis("SIP/1000-0000023e", "hello-world") in new stack

wscat отобразит событие StasisStart

При помощи curl скажем Asterisk воспроизвести hello-world, где 1429608436.4119 - «id»: «1429608436.4119» - StasisStart
