Session Stateful Proxy

The session stateful proxy mode:

• Maintains dialog state as a proxy.
• Includes BYES (though cannot be inserted)
• Keeps transaction state (timers and retransmission)
• Provides per-session information such as session counters per session agent, RADIUS STOP accounting record generation, CALEA CDC generation.
• Enforces session restrictions (32k) because of state management.
• Does not provide media management. There is no CALEA CCC.
• Routes full sessions with transaction timers with local policy routing and ENUM routing.
