IClient is the main class of the SDK that provides access to Voximplant’s functions, the VoximplantSdk.GetClient() method is used to get its instance:
VoximplantSdk.Initialize();
_client = VoximplantSdk.GetClient();
_client.Connected += ClientOnConnected;
_client.LoginSuccess += ClientOnLoginSuccess;The IClient.State property is used to get the current state of connection to the Voximplant cloud and perform the actions according to it.
private void LoginWithPassword(string login, string password) {
_login = login;
_password = password;
if (_client.State == ClientState.Disconnected)
{
_client.Connect();
}
else if (_client.State == ClientState.Connected)
{
_client.Login(_login, _password);
}
}
private void ClientOnConnected(IClient sender)
{
_client.Login(_login, _password);
}
private void ClientOnLoginSuccess(IClient sender, LoginSuccessEventArgs e)
{
_displayName = e.DisplayName;
}To initiate a call we need the IClient.Call() method. There is a CallSettings class which could contain custom data and extra headers (SIP headers).
Since the call can behave in different ways, there is a group of call events. They can be triggered by the ICall instance as the class contains all the functionality for call management.
private ICall MakeAudioCall(string number)
{
var call = _client.Call(number, new CallSettings());
if (call == null) return null;
call.Disconnected += OnCallDisconnected;
call.Failed += OnCallFailed;
call.Connected += OnCallConnected;
call.Ringing += OnCallRinging;
call.AudioStarted += OnCallAudioStarted;
call.Start();
return call;
}
private void OnCallConnected(ICall sender, CallConnectedEventArgs e)
{
Debug.Log("Call connected");
}IClient.IncomingCall event handler is used to get incoming calls.
There are two methods for an incoming call: answer and reject. An audio stream can be sent only after the answer method call.
VoximplantSdk.GetClient().IncomingCall += OnIncomingCall;
private void OnIncomingCall(IClient sender, IncomingCallEventArgs e)
{
sender.Answer(new CallSettings());
}Call can be put on/off hold
_call.Hold(true, error =>
{
if (error != null)
{
Debug.LogError(error.Value.Message);
}
