You are on the right page for getting instructions on how to configure a C# open source VoIP softphone with WPF GUI using Ozeki SIP SDK. Follow the steps to experience how easy and efficient this sample program to use.

Just a quick check before start: Does your system meet the requirements?

Requirements

• Operating system (Windows XP; Vista, 7, 2003, 2008)
• .Net compatible development kit (e.g. Visual Studio 2010 / Visual C#)
• Minimum .Net 3.5 SP1
• SIP account from your service provider
• Ozeki VoIP SIP SDK

How to configure Ozeki WPF softphone sample program:

1. Download and extract the sample program



2. Load it into Project Visual Studio 2010



3. For the proper operation of the program a minimal configuration is required:

In the following section of PhoneWindow.xaml.cs file you need to replace some parameters:

private void InitializeSoftPhone()
        {
            softPhone = SoftPhoneFactory.CreateSoftPhone("192.168.91.42", 5700, 5750, 5780);
            softPhone.IncomingCall += new EventHandler<VoIPEventArgs<IPhoneCall>>(softPhone_IncomingCall);
            phoneLine = softPhone.CreatePhoneLine(new SIPAccount(true, "oz891", "oz891", "oz891", "oz891", "192.168.91.212", 5060));
            phoneLine.PhoneLineInformation += new EventHandler<VoIPEventArgs<PhoneLineInformation>>(phoneLine_PhoneLineInformation);

            softPhone.RegisterPhoneLine(phoneLine);
        }





In this line you need to replace the local IP address of the running system instead of "your local IP Address" section:

 softPhone = SoftPhoneFactory.CreateSoftPhone("your local IP Address", 5700, 5750, 5780);
 





Then you need to provide the user data of the chosen SIP PBX as the data of the SIPAccount object, similarly to the following line:



phoneLine = softPhone.CreatePhoneLine(new SIPAccount(true, "oz891", "oz891", "oz891", "oz891", "192.168.91.212", 5060));

4. When you are finished with it you only need to build and run the program.
