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.
