After getting started, this page exists to discuss some utilization possibilities of the C# Callback form using the Ozeki C# SIP VoIP softphone source. Learn how you can utilize this example before you start configuration steps.

The Ozeki Callback Form sample program is intended to represent how to connect two phone calls by Ozeki VoIP SIP SDK.

For better understanding of its utilization let's see a simple example for using a Callback form:

In which cases a Callback form can be used and two calls need to be connected?

If a business is involved in selling products or services, there should be a website for this purpose (representing the products, the services, the company, etc.). For providing more appropriate information for customers it is possible to contact them via telephone. Live conversations have their own advantages. You can interact with customers and give the right answers according to their interests. For this purpose introducing a Callback form is a good idea.

You can place a callback form to your website. In this way, website visitors can fill the query form, provide a summary of the products/services they are interested in and enter their phone number. Therefore, their request can be directed to one of the experienced sales/support engineers.

When the Callback form is filled, the SDK calls the intended operator and the person who needs information at the same time. If both calls are accepted, then the SDK connects the two lines. In this way, the operator and the person who needs information can talk to each other.

This sample program represents this connection by using Ozeki VoIP SIP SDK. For implementing this solution you need to meet the following technical prerequisites:

  • Technical knowledge to introduce Ozeki SDK: It does not require any special knowledge. Basic knowledge for C# programming is a further help.
