When I had called IRS (Internal Revenue Service) thru video relay service that I have questions regarding about refund checks. When I called them through HOVRS, IRS asked if HOVRS are using federal interpreters, and the interpreter says, "No, we are not federal interpreter." They said they won't talk to me unless they talk to me on TTY. I told them I don't have TTY and VP is the only way I can communicate with hearing people is through VRS. I tried to use TTY software using Nextalk but still it won't work with Nextalk because it had to hear if there is TTY is on the phone. I did tap the space bar so the computer can hear the TTY but it hung up on me. Why IRS won't talk to video relay interpreter if I am only one here to see the interpreter?? Anyone has problem talking with IRS using video relay?? Why do they need federal interpreter??
