This test suite offers key functions such as proxying SIP messages from the subscriber to the IMS network, establishing IPSec tunnels between the subscriber equipment and IMS network and the protection of the IMS core against SIP message floods.
Since the P-CSCF acts as a conduit for the user interactions with the IMS core, the ability of the IMS core to provide IMS services such as Presence, Voice Calls, IP Centrex service and Conference services can be negatively impacted by the P-CSCF.
The P-CSCF solution focuses on testing these key functions to ensure the IMS network reliability. It emulates the IMS subscribers supporting IMS AKA and IPSEC, and the rest of the IMS core network, which includes the I/S-CSCF and HSS on a single test platform.
