THN Thinkengine Networks,

ThinkEngine Networks, Inc. (AMEX: THN) today announced that O1 Communications has selected the VSR1000 to power its new audio conferencing service. The new service offers customers reservationless conference calls in the first phase and soon will enable the use of enhanced features such as call recording, PIN administration and other call management functions. O1 offers the service to new and existing enterprise customers and will also private label the solution as it has done for providers such as FreeVoiceConferencing.com. �Our experience with a home-grown product proved to lack scalability, so we searched the market for a scalable, flexible solution,� said Brad Jenkins, President and CEO of O1. �ThinkEngine�s VSR1000 was the perfect fit. It�s highly scalable, going to 968 ports in a 1U. It also gives us lots of flexibility being able to support both TDM and VoIP in the same chassis, and is extremely easy to operate. We literally had calls up and running within a day.� The O1 and ThinkEngine teams worked very closely through the decision process, defining the needs for the platform and ultimately customizing it to O1�s specifications. This was a deciding factor in the choice of ThinkEngine and the VSR1000. �Customers like O1 understand the price-performance equation the VSR1000 offers,� said Mike Wixon, VP of Product Management at ThinkEngine. �With built-in TDM and IP support, customers have the flexibility to deploy and migrate traffic between TDM and IP at will. In addition to richly featured reservationless conferencing, O1 and ThinkEngine plan to work together to address new markets and revenue opportunities.�ThinkEngine�s graphical Call Flow Designer tool will be employed to rapidly implement these new services, leveraging the VSR1000 platform for multiple services.� About ThinkEngine Networks: ThinkEngine Networks is a leading provider of TDM and IP capable conferencing bridges and media servers.
