Develop a new application that calls the REST interface.


Example

We can copy the following example code into an HTML file and preview it as part of a sample application. The code renders as a simple form where the user can enter two SIP URIs that represent two phones. When the Send XML button is pressed, the request is sent in XML format to the REST interface and a call is established. If the Send JSON button is pressed, the only difference is that the format of the request is JSON. The response is of the associated format and printed to a popup window. This example shows only one of the available REST interfaces.
