Acme Packet, the leader in session border control solutions, announced that Brasil Telecom, the third largest fixed line service provider in Brazil, has selected its 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.

Brasil Telecom is using Acme Packet's Net-Net SBCs to provide trusted, high-quality delivery of business and residential VoIP services throughout Brazil. 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.

"In our rigorous lab testing, Acme Packet demonstrated its SBC can deliver the rich set of functionality that we require to support our services," said Marcelo Frasson, Network Planning Director at Brasil Telecom. "With its local support, Acme Packet is helping us to deliver high-quality, revenue-generating real-time voice and multimedia IP services to our existing customers as well as attract new customers with premium offerings like instant messaging and presence services."

"This deployment demonstrates our leadership and commitment to the South American region in general and Brazil in particular," stated Andy Ory, president and CEO, Acme Packet. "In addition to our sales and technical support through global partners, Acme Packet is present in Brazil to give complete support to customers like Brasil Telecom."
