Hello @jcolp (I didn’t want to disturb you but I desperately need some help to get my code working as my deadline is about to hit). I read the other posts about externalmedia and your answers but I still can’t figure out what is wrong with my code.
I’m using Asterisk 23.1.0 for an AI agent.
What I’m trying to do is connecting ari and starting an externalmedia websocket connection for audio receiving. I’m planning to handle calls with ari and process the audio through a realtime openai session.
ari.ts
import ari, { Bridge, Client } from 'ari-client';
import "./otel"
const ASTERISK_HOST = 'localhost';
const ASTERISK_PORT = 8088;
const ASTERISK_USER = '......';
const ASTERISK_PASS = '.......';
const APP_NAME = 'audio-app';
import net from 'net';
// --- AYARLAR ---
const ASTERISK_URL = 'http://localhost:8088/ari';
const MEDIA_SERVER_PORT = 4096;
const MEDIA_SERVER_IP = '127.0.0.1';
const mediaServer = net.createServer((socket) => {
console.log('Asterisk medya sunucusuna bağlandı!');
socket.on('data', (data) => {
console.log(data.toString())
});
socket.on('end', () => {
console.log('Medya akışı bitti.');
});
});
mediaServer.listen(MEDIA_SERVER_PORT, () => {
console.log(`TCP Media Server ${MEDIA_SERVER_PORT} portunda dinliyor...`);
});
ari.connect(ASTERISK_URL, ASTERISK_USER, ASTERISK_PASS)
.then((ari) => {
ari.start(APP_NAME);
console.log('ARI Başlatıldı, çağrı bekleniyor...');
ari.on('StasisStart', async (event, incomingChannel) => {
console.log(`Çağrı geldi: ${incomingChannel.caller.number}. Analiz yapılıyor...`);
await incomingChannel.answer();
const bridge = await ari.bridges.create({ type: 'mixing' });
await bridge.addChannel({ channel: incomingChannel.id });
const externalMediaChannel = await ari.channels.externalMedia({
app: APP_NAME,
external_host: `${MEDIA_SERVER_IP}:${MEDIA_SERVER_PORT}`,
format: 'slin16',
encapsulation: 'audiosocket',
transport: 'tcp',
connection_type: 'client',
direction: 'both'
});
await bridge.addChannel({ channel: externalMediaChannel.id });
console.log('Sistem hazır! Ses akıyor, ARI kontrolü bizde.');
incomingChannel.on('StasisEnd', async () => {
console.log('Çağrı bitti, temizlik yapılıyor.');
try {
await bridge.destroy();
await externalMediaChannel.hangup();
} catch {
}
});
});
})
.catch((err) => console.error(err));
