iDIRECT and DTECH LABS Successfully Test WHISPER - VoIP System to Provide Optimized VoIP Performance over the iDirect VSAT Platform

 


14 Aug 2007 | Results show VoIP call capacity increased by up to 600 percent, bandwidth efficiency boosted by more than 30 percent


 iDirect Inc (iDirect) and DTECH LABS Inc. today announced that the DTECH WHISPER™ VoIP System has been successfully tested on the iDirect iNFINITI VSAT broadband platform. The integration of the WHISPER system with the iDirect line of satellite hubs and remotes can provide end users with up to a 600 percent increase in VoIP call capacity over a single remote iDirect satellite link. The system can also reduce the amount of bandwidth required to support standard VoIP traffic by more than 30 percent.

With its reliance on large numbers of small, delay sensitive packets, VoIP traffic can quickly stress the resources of a remote satellite link. The WHISPER VoIP System, based on DTECH’s small-footprint, high-performance integrated hardware platform, is powered by VX Software from Network Equipment Technologies to deliver greater network efficiency through packet consolidation, header compression, and call consolidation.

This feature set reduces the number of packets and overhead required to support a VoIP call. A 1.5 Mbps iDirect satellite link can support more than 150 simultaneous VoIP calls, while a 3 Mbps remote link can support more than 250 simultaneous VoIP calls. The combined increase in calls per packet with the reduced bandwidth required allows network operators to utilize the same space segment they currently lease to provide a more robust voice network and greater capacity for data traffic.

DTECH LABS presently offers integrated iNFINITI/WHISPER solution sets in its line of Secure Mobile Communications Systems. Detailed test results can be obtained from both iDirect and DTECH LABS.

“Our combined customer base has been placing an increased importance, and reliance, on VoIP-based systems for their mobile and remote communications requirements. Our successful interoperability and performance testing has demonstrated the significant improvements and cost savings that can be had from an integrated iDirect/DTECH implementation.”
