Initialize the Plugin

• Before you can make or receive calls, you need to initialize the Linphone plugin and request the necessary permissions.

final _linphoneSdkPlugin = LinphoneFlutterPlugin();

Future<void> initLinphone() async {
  await _linphoneSdkPlugin.requestPermissions();
}

Login

• To start using Linphone, you need to log in with your SIP credentials.

Future<void> login({
  required String username,
  required String password,
  required String domain,
}) async {
  await _linphoneSdkPlugin.login(userName: username, domain: domain, password: password);
}

Make a Call

• Initiate a call by specifying the recipient’s number.

Future<void> call(String number) async {
  await _linphoneSdkPlugin.call(number: number);
}

Receive a Call

• You can listen for incoming calls and handle them accordingly.

_linphoneSdkPlugin.addCallStateListener().listen((CallState state) {
  if (state == CallState.IncomingReceived) {
    // Handle incoming call
  }
});

Hang Up

• End an ongoing call.

Future<void> hangUp() async {
  await _linphoneSdkPlugin.hangUp();
}
