Cisco ASR 5000 Series Product Overview ▄
OL-22938-02
The feature allows simultaneous support of IETF SIP and 3GPP/3GPP2 IMS/MMD clients.
MSRP Support
The SCM supports Message Session Relay Protocol (MSRP) session and page modes.
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.
