How to use OZEKI VoIP SIP SDK 1.9.2

To use OZEKI VoIP SIP SDK 1.9.2, you need to have Visual Studio 2010 or newer and a PBX installed on your PC (e.g.: Ozeki Phone System). You also need to have a connected softphone or a SIP account to make and receive calls.

After you have installed the NuGet Package Manager, you can download the project by Package Manager Console. You will see the added new VoIP SIP SDK Reference, and two added class files (CallHandlerSample.cs, TestCall.cs). The CallHandlerSample.cs file contains the code for managing making and receiving calls. The TestCall.cs file contains the code for testing the functionality of the project.

The following code snippet shows how to initialize the softphone object and register it to a SIP server:

private void InitializeSoftPhone (string registerName, string domainHost) softPhone = SoftPhoneFactory.CreateSoftPhone ( SoftPhoneFactory.GetLocalIP (), 5700, 5750, 5700); softPhone.IncomingCall += softPhone_IncomingCall; phoneLine = softPhone.CreatePhoneLine (new SIPAccount (true, registerName, registerName, registerName, registerName, domainHost, 5060), new NatConfiguration (NatTraversalMethod.None)); phoneLine.PhoneLineStateChanged += phoneLine_PhoneLineInformation; softPhone.RegisterPhoneLine (phoneLine);

The following code snippet shows how to make a call to a specified number:

private void PickUpButton_Click(object sender, EventArgs e) if (phoneLineInformation == PhoneLineState.RegistrationSucceeded) if (!string.IsNullOrEmpty(dialNumber)) call = softPhone.CreateCallObject(phoneLine, dialNumber); call.CallStateChanged += call_CallStateChanged; call.Start();

The following code snippet shows how to accept an incoming call:

private void softPhone_IncomingCall(object sender, VoIPEventArgs<IPhoneCall> e) InvokeGUIThread(() => MessageBox.Show("Incoming call from: " + e.Item.DialInfo.ToString()); ); call = e.Item; WireUpCallEvents(); call.Answer();
