Our hosting services are run from our own data centers, which extend across four redundant sites in Deerfield, Illinois; Chicago, Illinois; Aurora, Colorado; and Southfield, Michigan. These data centers are all interconnected by Level 3 Communications carrier-grade broadband services, and their facilities are protected by complete power backups, restricted personnel access, and environmental control systems, including chemical fire suppression. And if a larger service capacity is needed, the modular architecture of the platform makes adding a new server a simple business of plug-and-play.
Most of the data centers contain redundant telephony access points, which protect our servers against a local fiber cut. In the event that a carrier experiences an outage, all traffic can be moved to another carrier without interruption. Every detail has been provided for.
Each site is made up of a number of SIP-based VoIP processing cells. Individual servers in each cell are Intel-processor-based computers running Solaris, LINUX, or Microsoft Server 2005. These servers run numerous processes including automated speech recognition (ASR), text-to-speech (TTS), call conferencing, messaging (voicemail, e-mail, FAX, paging), call analysis, and web services, all without the need for any traditional telephone or switching equipment.
All sites are connected to multiple providers, both local and long-distance, via multiple DS3-level access points on a SONET Ring. Today, Vail has IP voice connection and PTSN connectivity with AT&T, Level(3), Global Crossing, and Verizon, as well as PTSN exclusively for Focal and British Telecom.
For Internet connectivity, Vail also runs multiple data service providers in tandem. These providers are all fully redundant, and a multi-conduit Gig-E connection links data centers. If Internet access is lost at either site, traffic is seamlessly routed via our WAN connections.
With over fifteen years of experience in the telecommunications business, Vail is ready for any possible problem's no matter how unusual. We know that "an ounce of preparation is worth a pound of cure," and we are prepared.
