Is anyone else having this problem? The screeching starts when the caller presses "9" to begin a new dictation. If they dictate over the noise, the recording sounds fine; I do not hear the noise when transcribing. It only happens to callers on Verizon phones (landline or cell) or T-Mobile. AT&T and Credo callers get through w/o any problem. NCH Tech was unable to solve the problem for me. They claim only one other user in the U.S. is having this issue. Thanks all!
