Objectives of the projectSupply telecommunication providers with

the ability to:

Provide a service of call authorization for their clients.

Provide a service of secured communication to their clients.

Provide the ability for dynamic configuration of call authorization rules by the users of that service.

CCA – Communications Control ApplicationThe CCA is an event driven application that

runs on a JSLEE server.

It provides several services for telecommunications clients

In order to create an application for which services can be added easily, the following architecture was selected for the CCA:

CCA classes Description

Authorization, Availability and Security SBB's all handle the INVITE event.

In order to control the order in which they handle it, their priority is defined.

Each of these SBB's can prevent the handling of that message by the following SBB's

CCA classes Description (cont’d)

The ReadinessSBB waits for a reply of successful configuration of IPSec from the enablers of the caller and callee.

RedirectSBB sends a REDIRECT response to the caller with the callee's IP.

For communication with the Enabler, the SIP protocol is used as well.
