Presence Enabled
With its high transaction setup rate, this is an ideal solution to handle a large number of messages generated by presence
signaling. CSCF supports all the presence RFC extensions and signaling and interoperates with several presence servers.

Redirection
The SCM supports response to 3xx redirect messages. In addition to supporting redirection as per 3GPP, it supports call
redirection to other chassis in the network (based on configuration) in case of system overload.

Redundancy and Session Recovery
When enabled, provides automatic failover of existing CSCF sessions due to hardware or software faults.
The system recovers from a single hardware or software fault with minimal interruption to the subscriber’s service and
maintains session information to rebuild sessions if multiple faults occur.

Registration Event Package
A set of event notifications used to inform SIP node of changes made to a registration.
Signaling Compression (SigComp)
SigComp compresses SIP call setup messages and is supported on the P-CSCF component. This reduces bandwidth
demands on the RAN and reduces setup times.

SIP Denial of Service (DoS) Attack Prevention
The A-BG provides a scalable proxy network and a distributed Network Address Translation (NAT) network which
effectively mitigates DoS attacks.

Prevents a variety of DoS attacks specific to CSCF and SIP technology.
SIP Intelligence at the Core
The SCM provides operators with an easy on-ramp for deploying SIP-based subscriber services while supporting
various network control operations that provide the necessary intelligent control to insure a robust, carrier-class
subscriber experience is achieved in this always changing multimedia environment.

When integrated into Cisco's session-aware Home Agent or GGSN platform, the SCM becomes the first SIP hop in the
network, allowing operators to monitor and control all SIP-based sessions and execute additional value-added functions.
