Call Blocking

This sample uses the SIP Servlet 1.0 application programming interfaces (API) and provides a web interface that you can use to create a list of blocked incoming FROM SIP Address for specifics TO SIP Addresses. For incoming calls, the SIP servlet verifies if the caller's SIP address is on the list of addresses to be blocked by the callee. If positive, the call is blocked and a 406 (Not Acceptable) Response is sent to the caller.
