'Telefonica O2 picks Acme Packet SBCs for IMS functionality'

Telefonica O2 Germany has selected Acme Packet's session border controllers to provide key IP multimedia subsystem functionality at its access and interconnect borders. The Acme Packet Net-Net Session Director will replace an older VoIP platform and enables Telefonica O2 Germany to deploy a secure and interoperable IMS network supporting residential retail and wholesale VoIP services and IP interconnects with other service providers. Telefonica O2 Germany also uses the Net-Net SBCs to securely interconnect with other tier 1 service providers for off-net call origination and termination. Telefonica O2 Germany selected Acme Packet's Net-Net 4500 SD to meet critical 3GPP IMS functional requirements at the access and interconnect borders of its network. At the subscriber access border, the Net-Net 4500 SD integrates the Proxy-Call Session Control Function, the initial SIP signaling contact point for subscriber endpoints, and the Access Gateway Function for controlling subscriber media flows. At the interconnect border to other service provider networks, the Net-Net 4500 SD integrates the Interconnect Border Control Function (I-BCF), the SIP signaling point for sessions leaving or coming into the network, and the Transition Gateway (TrGW) for controlling associated media flows. Both the access and interconnect SBCs include a Signaling Firewall. Net-Safe, Acme Packet's security framework, provides denial of service attack prevention, topology hiding and access control to protect Telefonica O2 Germany's IMS network and ensure service availability. In addition, the Net-Net 4500 SD also provides multiple encryption capabilities, including IPsec using IMS-AKA and Transport Layer Security, for secured sessions between subscriber endpoints and Telefonica O2 Germany's IMS services network.
