Brasil Telecom, the third largest fixed line service provider in Brazil, has selected Acme Packet’s Net-Net session border controllers (SBCs) for VoIPfone service, a SIP-based business and residential VoIP offering. The Net-Net SBCs are also deployed in Brasil Telecom network supporting Multiconferencias, an IP-based multimedia conference service.
The Acme Packet session border controllers are providing access control and complete network topology hiding for confidentiality and attack prevention. The denial of service (DoS) protection includes session agent DoS protection for protecting the service provider’s infrastructure (e.g., SIP servers, softswitches, application servers, media servers or media gateways) and session border control DoS protection, an autonomic self-protection against malicious and non-malicious DoS attacks and overloads. To extend its service reach, Brasil Telecom is using features including support for overlapping address using VLANs and Acme Packet’s adaptive hosted NAT traversal mechanism.
