Cisco SBC
Portfolio
• Network privacy (Proxy/NAT equivalent)
Provides the ability to “Peer” with other networks and only provide a single address/port hiding internal topology of a
SP Network
• Billing / CDR Normalization
With TDM or IP Trunks SP require a trusted device for CDR generation, IP-to-IP GW performs this function at the
edges of a SP network
• Quality of Service (QoS) / CAC Features
Configure Max. # of calls / Total BW on per call and aggregate to a peer
(Re) Mark TOS / DSCP Traffic from foreign service providers
• Interworking for call signaling and bearer level features
Interwork signaling protocols and codecs between networks
Networks in Protocol Transition: Transition from H323 to SIP based call control
• Security / DOS
Ability to deliver secure voice on an end-to-end basis (SRTP Transcoding in future)
Integration with the Cisco Threat Defense Initiatives with STG

Why Cisco Multiservice IP-to-IP GW SBC?
• Integrated into Cisco IOS® – no additional OPEX to operate
Cisco SBC
• No additional hardware CAPEX – As IP interconnects grow, reposition TDM-to-IP gateways to IP-to-IP gateways
• Enhanced DSP technology – ability to perform transcoding,
rich codec support, DTMF interoperability
• Rich signaling functions on call legs by applying TCL IVR or
VXML services
• Rich media functions – rotary, fax interoperability, modem
interoperability
• Customers can enable routing, voice GW, security and SBC
functions with LI on an IOS platform
