Accessibility
As much of the TRS system, particularly the Internet Relay Services, is open for public use; it is possible for anyone with the proper equipment to place calls. This includes people who are not members of the original intended user group, who are Deaf, Hard-of-Hearing, or Speech–Disabled. Some such users have noted its usefulness in making long-distance or local calls free of charge and without a telephone. Some providers have implemented long-distance billing, which bills long-distance calls just like a regular telephone. Providers defend the accessibility even to people who have neither hearing nor speech disabilities as a necessary evil. This is because the principle of "transparency" - the belief that the operator and the mechanics of relay should generally go as unnoticed as possible in the call - requires that relay be as easy to use as a normal telephone, which does not require any kind of verification for Hearing people to use. Leaders in the Deaf community defend this decision and generally retain strong support among service users with hearing and speech disabilities.
