A public accommodation responds to calls from a telecommunications relay service established under Title IV of the ADA in the same manner as other calls; it may use relay services in place of direct telephone communication (36.303(d)(3)) and need not use a TTY (36.303(d)(5)); where it offers outgoing calls on its equipment on more than an incidental basis, it makes accessible telephones, TTYs or equivalent products available (36.303(d)(2)).
