iBasis Selected by Vietnam's Largest Telecommunications Carrier to Expand Global Service

BURLINGTON, MA -- iBasis Inc., (Nasdaq: IBAS), a provider of Internet-based voice communications, announced that Vietnam Telecom International (VTI) is interconnecting with The iBasis Network. A subsidiary of the state-owned Vietnam Posts and Telecommunications Corporation (VNPT), VTI will expand its global service by leveraging iBasis' Tier 1 quality VoIP service. VTI's interconnection to iBasis will enable VTI to route its international voice traffic over The iBasis Network and allow iBasis to terminate international calls into Vietnam on VTI's infrastructure. According to the International Telecommunications Union, Vietnam is the third fastest-growing telecommunications market in the world. "As the largest carrier in Vietnam, in a rapidly-growing nation of more than 78 million people, we sought the best and most efficient global voice service available. With their extensive experience in major Asian markets and Tier 1 reliability, iBasis was our clear choice," said Mr. Nguyen Huu Khanh, deputy managing director at TI. "Our interconnection to The iBasis Network will enable us to expand our global reach while maintaining affordable, high quality service." "We are very excited at the prospects for our relationship with VTI, the telecommunications leader in a very fast-growing market," said Ofer Gneezy, president and CEO of iBasis. "VTI is taking the lead in introducing to its customers advanced services such as VoIP, which lower communications costs and expand economic growth. We look forward to providing our high quality international service to the people of Vietnam. And since Vietnam is a relatively high revenue per minute destination, as we ramp up our service with VTI over the next few months, we may see an increase of as much as 1. in our average revenue per minute (ARPM) network-wide."
