Client CSDVRS provides video relay services for the deaf and hard of hearing community in the United States. By 2001, they were the nation’s only 24/7 provider, and also the first to offer Spanish VRS, video mail, and Personal 800 Number.
Product Video Relay Service (VRS), allows deaf and hard of hearing people to communicate with hearing people via an interpreter at a CSDVRS call center. Using a video–enabled device (a special video phone, or soft–phone on a PC) and a digital connection, the deaf or hard of hearing person visually communicates (e.g. using American Sign Language–ASL) with the interpreter who then verbally communicates with the hearing person over a traditional audio phone call. The interpreter is specially trained and assures complete confidence to both parties on the call. Of course, hearing people can also call a user of the VRS system.
Project CSDVRS approached Magpie for our SIP (Session Initiation Protocol) technology experience and expertise with communication–enable applications. Their system was H.323 based and they were in the process of evolving to SIP.
Outcome Magpie reviewed, assessed, and provided recommendations on the CSDVRS SIP architecture directions. Magpie then implemented a SOAP interface to Neustar’s iTRS ENUM database to keep it up–to–date with telephone numbers of CSDVRS customers. In addition, Magpie developed a proxy capability to keep the Intrado database updated for accurate routing of VRS 911 calls to the appropriate PSAP. And finally, Magpie implemented configuration managers for automated provisioning of their Z video phones along with some video phone device verification testing.
Magpie’s SIP, 911, and extensive telecom experience contributed to the successful release of the CSDVRS SIP based service. The Vice President of Product Development at CSDVRS commented, “Over the past 10 months, I have had the opportunity to call upon Magpie’s services for architectural design, software development and systems testing. The Magpie management team and development team were always very responsive, very knowledgeable, and very experienced. We were developing a SIP platform for the very first time and their expertise was extremely valuable. They met tight schedule commitments and delivered quality software.”
