A Uniform Numbering Scheme for VRS Users and Providers North American Numbering Council January 24, 2006
VRS Overview Video Relay Service (VRS) is a form of Telecommunications Relay Service that enables persons with hearing disabilities who use American Sign Language (ASL) to communicate with voice telephone users through video equipment rather than through typed text. • Users are able to more fully express themselves through facial expressions and • body language, which cannot be expressed in text. • Calls flow back and forth like hearing calls • and both users have the ability to “interrupt”. • Because of more natural flow, the same conversation • is typically shorter in VRS than text-based TRS. • VRS Calls may be between ASL and either English • or Spanish. 2

Functional Equivalence Issue • System Works Fairly Well for Deaf-initiated Calls. • Hearing-initiated Calls Are More Problematic. • Hearing User Must Know: • Which VRS Provider to Contact; • The Type of “Identifier” Used by that provider; • Psuedo Phone Number • “Extension” Number • User Name • IP Address • The Specific Identifier for the Deaf Party • E911 PSAP Call-back Issue 7
VRS and the NANP • Placing VRS Endpoints on the NANP would approach functional equivalency for Deaf and Hard-of-hearing. • Hearing User Dials Deaf User’s Unique 10-digit Telephone Number. • Carrier Identification Code used to Route to Appropriate VRS Provider. • Similar Implementation to VoIP. 8
