Korea Telecom (KT (News - Alert)), Korea's integrated wired and wireless communications service provider, has announced it is extending its relationship with Acme Packet and will deploy Acme Packet's (News - Alert) Net-Net session border controllers (SBCs) for their international VoIP peering service.

 

A session border controller (SBC) is used to mediate the differences in various IP networks and to provide security, quality and cost control at the border of these networks.

 

Acme Packet session border controllers deliver critical control functions to enable trusted and supreme communications which includes; voice, video and multimedia sessions across IP network borders.

 

As per the latest announcement, Acme Packet’s Net-Net SBCs are deployed to support five VoIP and IMS projects at KT.

 

KT is using the Net-Net Session Director, deployed in KT’s international switching center in Seoul, to securely interconnect with over 30 domestic and international service providers.

 

Upon completing trials in 2007, Acme Packet’s Net-Net SBCs were chosen for KT’s international VoIP interconnect service.

 

An Acme Packet customer since 2005, KT uses Acme Packet SBCs to support its residential and business VoIP services and domestic VoIP interconnects, which went into production earlier this year.

 

“From years of experience using Acme Packet’s session border controllers, KT is very familiar with the comprehensive security and control features they provide to our network,” said Eun-Sik Shin, Director, Network Group, for KT.

 

“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,” added Shin.

 

Acme Packet’s Net-Net SBCs completely satisfy KT’s critical security at the interconnect borders thereby assuring service maximization, SLA assurance and revenue and cost optimization requirements.

 

Using SIP and H.323 signaling, as well as SIP-H.323 interworking, on Acme Packet’s SBCs, KT is able maximize the number of networks it can connect to and minimize required changes to its core VoIP network.

 

“Large, international service providers like KT are accelerating the worldwide trend of offering VoIP interconnects to other service providers for PSTN or IP termination, bringing cost savings and increased revenue opportunities to both,” said Seamus Hourihan (News - Alert), vice president of marketing and product management.
