Steps
Enable the HTTP server in http.conf (enabled=yes, default bindport 8088) — ARI is disabled by default.
Define an ARI user in ari.conf (type=user, password, read_only as needed).
Route a call into ARI from the dialplan using Stasis(app-name[,args]) — the channel is ejected back to the dialplan immediately if no websocket for that app is connected.
Connect a websocket to /ari/events with an api_key query param and app name to receive StasisStart/StasisEnd and other subscribed events.
Control the channel via REST calls under /ari/channels/{channelId}/... (e.g. play, answer, hangup) using HTTP Basic auth.
Known gotchas
If no app is listening on the websocket when Stasis() runs, Asterisk immediately returns control to the dialplan — the channel never reaches ARI.
StasisEnd means ARI no longer controls the channel — don't issue further REST commands against it afterward.
ARI is off by default in http.conf; a fresh install needs explicit enabling before any ARI call will work.
