The SIP Toolkit contains several Samples that demonstrate particular Session Initiation Protocol (SIP) capabilities. Go to Samples Gallery from the Help Menu, then Select Technology Samples, then SIP.
To access these Samples:
Call Blocking Sample: This Sample demonstrates the use of the SIP Servlet 1.0 application programming interfaces (API). This Sample checks a list to determine if the caller is valid. If the caller is not valid, the call is blocked. If the caller is valid, the call is forwarded.
Call Forwarding Sample: This Sample demonstrates the use of the SIP Servlet 1.0 application programming interfaces (API). This Sample checks to determine if the caller is in a forwarding list and forwards the call.
Third Party Call Control Sample: This Sample demonstrates the use of the SIP Servlet 1.0 application programming interfaces (API). This sample demonstrates how to use the Converged capability by implementing a controller which sets up and manages a communications relationship between two parties.
