Brasil Telecom opted to deploy Acme Packet's Net-Net session border controllers (SBCs) to introduce VoIPfone service, a SIP-based business and residential VoIP offering. The companies made the announcement on Monday. The Net-Net SBCs were also deployed in Brasil Telecom network supporting Multiconferencias, an IP-based multimedia conference service.
Brasil Telecom is using Acme Packet's (News - Alert) Net-Net SBCs to provide the delivery of business and residential VoIP services throughout the South American country. The Acme Packet session border controllers provide access control and network topology hiding for confidentiality and attack prevention.
"In our rigorous lab testing, Acme Packet demonstrated its SBC can deliver the rich set of functionality that we require to support our services," stated 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."
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.
"This deployment demonstrates our leadership and commitment to the South American region in general and Brazil in particular," said Acme Packet's president and CEO Andy Ory in a statement. "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."
The VPF ENUM Registry resolves E.164 numbers to URIs and the VPF SRV Registry resolves domain names to specific IP addresses for call routing. VoIP calls terminated using these registries stay on IP networks end-to-end, bypassing the PSTN, and can be completed at no cost to VPF members.
