The document discusses proposals for assigning telephone numbers to users of video relay services (VRS) to provide functional equivalence to emergency services and direct dialing capabilities. It describes AT&T's preference for a model where VRS users get numbers from their chosen provider, and a centralized database containing numbers and IP addresses is maintained using DNS and updated by each user's provider. This would allow any provider to directly connect with any user for VRS calls or direct dialing between deaf users.
