Sip.js Reconnection Issue when Web socket connection Lost or Network connectin lost

[m-yunus]

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.

Is there any solution on this, How to handle the same ?

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);
};
