Sip.js Reconnection Issue when Web socket connection Lost or Network connectin lost
I am facing an issue with reconnection handling in SIP.js when the WebSocket connection is lost or the network is disconnected. After a disconnection, the onDisconnect delegate is triggered, but the UserAgent doesn't reconnect properly, and I can't maintain registration automatically.
const transportOptions = {
server: "wss:///ws",
traceSip: true,
iceCheckingTimeout: 35000,
register: true,
stunServers: ["stun:stun.l.google.com:19302"],
turnServers: [
{
urls: "t",
username: "",
credential: "",
},
],
connectionTimeout: 5,
maxReconnectionAttempts : 100,
reconnectionTimeout: 4,
keepAliveInterval: 10
};
const handleRegister = (event) => {
const uri = UserAgent.makeURI(sip:${sipUri}@);
const userAgentOptions = {
authorizationUsername: sipUri,
authorizationPassword: "",
transportOptions,
uri,
delegate: {
onInvite,
onDisconnect: (error) => {
alert("disconnected")
console.log("Network connectivity lost");
if (!error) {
console.log("User agent stopped");
}
},
onConnect: () => {
alert("connected")
handleRegister();
console.log("Network connectivity established");
},
}
};
const ua = new UserAgent(userAgentOptions); setUserAgent(ua);
ua.start() .then(() => { const registerer = new Registerer(ua); return registerer.register({ requestDelegate: { onAccept(response) { isRegistering = false; alert("registerred successfully") console.log("UserAgent registered successfully", response); }, onReject(sip) { isRegistering = false; // Reset flag on failure console.log("UserAgent registration failed", sip);
},
},
});
}) .catch((error) => { isRegistering = false; console.error("Error starting the UserAgent:", error); }); } I’ve reviewed the SIP.js documentation and attempted to use the onDisconnect and onConnect delegates for handling reconnections, but I'm unable to achieve reliable re-registration.
Any guidance or recommendations would be greatly appreciated.
You have to call reconnection method inside onDisconnect delegate. Like,
const reconnectionAttempts = 3;
const reconnectionDelay = 4;
let attemptingReconnection = false;
let shouldBeConnected = true;
userAgent.delegate.onDisconnect = (error) => {
if (error) {
attemptReconnection();
}
};
const attemptReconnection = (reconnectionAttempt = 1)=> {
// If not intentionally connected, don't reconnect.
if (!shouldBeConnected) {
return;
}
// Reconnection attempt already in progress
if (attemptingReconnection) {
return;
}
// Reconnection maximum attempts reached
if (reconnectionAttempt > reconnectionAttempts) {
return;
}
// We're attempting a reconnection
attemptingReconnection = true;
setTimeout(() => {
// If not intentionally connected, don't reconnect.
if (!shouldBeConnected) {
attemptingReconnection = false;
return;
}
// Attempt reconnect
userAgent.reconnect()
.then(() => {
// Reconnect attempt succeeded
attemptingReconnection = false;
})
.catch((error) => {
// Reconnect attempt failed
attemptingReconnection = false;
attemptReconnection(++reconnectionAttempt);
});
}, reconnectionAttempt === 1 ? 0 : reconnectionDelay * 1000);
};
i dont hear anything on when an outgoing call not hearting early media any issue on this
After network reconnection (e.g., switching from Wi-Fi to mobile data), the WebSocket and SIP session reconnect successfully. However, even though the call continues and ICE renegotiation completes without errors, audio is not heard on either side post-reconnection.
I have the same issue - It seems that the local web RTC connection remains in place when the connection is lost and then recovered. There should be a renegotiation or some kind of web RTC rebuild to hook up the session after the reinvite.
