Inter Chassis Session Recovery
• Provides 1:1 redundancy in case of failures
• Uses propriety Service Redundancy Protocol (SRP) over TCP link
• Needs a separate context for SRP
• Configuration must be identical
• Tasks peers between two chassis
• Session states are synchronized between the chassis pair
• Session states checkpoint starts after 60 seconds for call establishment
