Korea's Largest Mobile Operator Turns to TelcoBridges to Scale its Ring Back Tone System

SK Telecom Addresses Its Current Needs and Also Plans to Face Future Growth by Leveraging TelcoBridges’ Highly-Scalable Telecom Platform

Montreal, Canada, May 27, 2008 – TelcoBridges™ Inc., the preferred hardware and software supplier for telecom solution developers, and Alox Inc, a leading solution provider in Korea, today announced that they are working together to scale SK Telecoms Ring Back Tone system, in a manner that meets current operators demand and also provides added capacity to address SK Telecoms future growth needs.

Alox is a leading solution supplier for the telecommunication market in Korea, specializing in Ring Back Tone systems and converged telephony applications. TelcoBridges provides the industrys most scalable telecom hardware platforms. By combining Aloxs application software with TelcoBridges award-winning hardware, the two companies have delivered a new and substantially larger Ring Back Tone system to SK Telecom, which is the largest CDMA service provider in Korea.

SK Telecoms new Integrated Color-Ring Back Tone System (iCRBT) replaces a previous system that had reached its limits. The new iCRBT system provides extensive capacity (up to 256 E1s per system, with multiple systems working in tandem) enabling SK Telecom to effectively compete with other mobile operators offering similar services, while also helping to reduce their operating expenditures. TelcoBridges Voice Trunking and SS7 switching technology provides a scalable foundation – without a single point of failure – that SK Telecom needs to support millions of current and future subscribers.

“Some of the largest systems in the world are currently running on TelcoBridges hardware, and were pleased to add SK Telecom to our portfolio of customers,” said Gaetan Campeau, President of TelcoBridges. “Our platform achieves greater scalability and reliability than any other system presently on the market, which is critical for operators like SK Telecom, who seek to provide high-margin services like ring-back tones to as many customers as possible.”

SK Telecoms new iCRBT system allows the called party to select from a variety of personalized voice recordings, songs, or sound effects to be played instead of a normal ring tone. Because iCRBTs are not dependent on network technologies or handset capabilities, any mobile user is a potential client. Ring Back Tone services require the user to have a subscriber account. Next to SMS, RBTs provide the second-most profitable value added service to carriers, so the underlying technology used to support RBT systems must be highly scalable.

“Scalability and flexibility are critical requirements to SK Telecom, because they serve millions of customers, and they need to be able to roll out new services in a manner that does not disrupt their business, or their customer service,” said Alox Deputy Manager, Seung Youl Maeng. “By working with TelcoBridges, were able to implement a Ring Back Tone system that vastly improves the customer experience, while also providing the scalability needed to meet future demand in a straightforward manner.”
