Spring 2002 Voice on the Net

SAN JOSE, Calif.--(BUSINESS WIRE)--April 10, 2002

Award-winning product allows carriers to exchange SIP calls

across an IP link without gating through the PSTN 

Extending its lead in the hotly contested inter-carrier VoIP call peering arena, Jasomi Networks today unveiled its line of SIP to SIP gateways that enable call hand-offs between carriers and service providers that use IP to link their networks instead of the PSTN.

PeerPoint, the award-winning debut product from Jasomi Networks, solves an important and vexing problem for VoIP carriers - how to demarc a call at the edge of one carrier's network before it is passed on to another carrier. Call demarcation is important because without it, the many data streams that constitute each VoIP call cannot be correlated and controlled in a manner that allows billing and security to be maintained. Additionally, calls may need to undergo a variety of transformations as they are handed off from one carrier, and accepted by another. These transformations include network address translation, IPv4 to IPv6 conversion, digit manipulation, and QoS remarking.

Until now, VoIP call carriers wanting to exchange calls with each other securely have had to gate their calls across the PSTN, which is expensive and inefficient, and can reduce voice quality. PeerPoint lets carriers perform direct IP to IP hand-offs of SIP calls without using the PSTN, bringing a significant improvement in performance, efficiency, and economy.

PeerPoint can also protect the networks of carriers completing calls from the Internet and from instant messaging services such as those being proposed by Microsoft and AOL.

"Over the last 6 months, we've seen the interest in direct SIP to SIP call hand-offs increase exponentially among both wireless and wireline service providers," said Dan Freedman, CEO of Jasomi Networks. "PeerPoint is the first product on the market that lets carriers directly route call signaling and media flows into each other's networks without losing control of access to their own internal network, and without releasing sensitive business information such as call routes to competitors."

PeerPoint protects a carrier's VoIP networks from attack or abuse from the outside world, while enabling the ability to accept and dispatch calls efficiently across other carriers' networks. It can also ensure that sensitive business information such as call completion routes or originating and destination telephone numbers are not released to upstream or downstream competitors. For carriers that do not own all of their own PSTN gateways, PeerPoint can enforce timed call termination - particularly useful for prepaid minute resellers that want to dispatch each call to the best available completion partner.

How PeerPoint works

PeerPoint employs a back-to-back user agent technology base tied to an integrated media proxy. Each call is split into two half-calls, and PeerPoint controls the signaling and media streams of both halves. One half-call is designated as "external" to the carrier, and the other is "internal". To all of the other equipment involved in completing a call, PeerPoint appears as a call termination point in much the same way as an IP to PSTN gateway appears to terminate a call.

In a separate announcement, Jasomi Networks today unveiled its CALEA legal intercept technology platform which, for the first time, enables the many and varying IP streams that make up each VoIP call to be collected and forwarded to law enforcement agencies.

Both technologies are being demonstrated at the Spring 2002 VON Show in Seattle, April 9-11 2002 (www.pulver.com/von). Further information about these unique offerings can be found at www.jasomi.com.
