A CPE is Most Often Required Anyway A SIP Proxy Based E-SBC, also routing media, can do it all Such are also used for security, SIP normalization, QoS, failover and features And while routing SIP, it can add the functions found in Soft Switches Centralized SBCs doing the NAT traversal, require an individual pipe (e.g. MPLS or other “VPN”) to the each LAN (security concern also) …often ending up in an expensive Telco deployed CPE anyway Handling many users, makes it a critical point of failure – Duplication and failover capability by an E-SBC is often required
