The VPF is built as a distributed private Ethernet network. The network consists a series of Force10 Network E-Series Ethernet Switches connected by dark fiber and wavelength connections. Nodes of the VPF are located in fiber-dense co-location sites, many of which are landing sites for undersea cables stretching to different islands and continents.


VPF functions as a meet-point for service providers and enterprises to exchange voice and telephony related services. The service provides an economical traffic exchange environment where members can directly connect to each other, avoiding unnecessary delays and relays of the public Internet.


Based on VPF's Layer-2 Ethernet architecture, there is no VPF-installed voice gateway or switches between peers of the fabric. It is a pure Ethernet network supporting security and quality at the highest level. Based on this architecture, VPF is also protocol agnostic -- allowing members to communicate with any protocols of their choice.

Stealth initially introduced the VPF service to simplify the interconnect process for VoIP carriers at the tel(X) NYC 60 Hudson St Facility in Oct of 2003. By the end of 2005, the Voice Peering Fabric was installed in 9 US cities and in London. VPF is ever evolving, in an aim to help simplify the business process of carriers and enterprises, through the introduction of new features.


Members of the VPF buy and sell voice origination / termination services and ASP services with complete transparency via the VPF Minutes Market and VPF ASP Market. In April of 2004, the VPF ENUM Registry was formally introduced to our

members to route telephone calls among one another directly across the VPF without transversing the traditional public telephone network. Later in 2006, the SRV Registry was launched to enable the routing of VoIP calls using E-mail like identifiers.


VPF sees tremendous activity everyday, carrying on average over 630 million minutes on a daily basis or over 230 billion minutes annually. VPF's ENUM registry holds over 28 million unique numbers and processes over 200 million calls annually.

The VPF community consists of organizations from various industries and markets.


Majority of the VPF Members are service providers who have unique network assets that provide other members competitive services and reach to regions and cities around the world. Since the VPF takes away physical barriers in communications, many of the carriers who once were providers of one another through resellers, now are free to meet, negotiate and connect networks directly on the VPF platform.


Partners of the VPF include co-location operators, Ethernet transport providers, software and hardware vendors. VPF has been a strong influence and push for hardware vendors to enable voice products with ENUM and SRV capabilities. Success of the community as a whole relies on members help each other without prejudice in the new telecom era.


In addition to working closely with our members and partners, Voice Peering Forum is an event host by Stealth Communications two to three times a year to assist our members and partners to network and discuss latest topics and trends in voice communications. The event has been successful due to continuous support from the community. From transitioning out of TDM to covering topics relating to Net Neutrality and Web 2.0 applications, the event has been attracting top executives from leading organizations.
