KT Chooses Acme Packet SBCs for International VoIP Peering Service
By Niladri Sekhar Nath, TMCnet Contributing Editor
Korea Telecom (News - Alert) announced today that it’s selected Acme Packet’s Net-Net session border controllers for its international VoIP peering service.
Located at interconnect borders with the company’s wholesale customers, Acme Packet’s (News - Alert) Net-Net session border controllers are capable of satisfying Korea Telecom’s critical security, service reach maximization, SLA assurance and revenue and cost-optimization requirements, according to the companies.
At these borders, Net-SAFE, Acme Packet’s security framework, provides denial of service attack prevention, access control and topology hiding required to protect KT’s (News - Alert) VoIP core network, company officials say.
The Net-Net SBCs also arbitrate differences between VoIP networks, including bridging overlapping IP address spaces and interworking and normalizing signaling protocols, according to the company. Using SIP and H.323 signaling, as well as SIP-H.323 interworking, on Acme Packet’s SBCs, KT will be able to take full advantage of the number of networks it can connect to and minimize required changes to its core VoIP network, according to Acme Packet.
“By taking advantage of KT’s strong global presence and the controls provided by Acme Packet’s SBCs, our domestic and international service provider customers can lower costs by leveraging our IP service infrastructure,” said Eun-Sik Shin, director of network group for KT.
