This Captioning Telephone allows you to “see” the phone calls you cannot hear.
It comes with a large display screen and has free voice-to-caption service to produce the text for the captions. No special equipment is required to make it work*, though a high speed Internet connection is required. One good feature is the ability to save captions for future.
The captioning function can be turned off and the Captioning Telephone will function like any other normal phone, including adjustable volume and an answer machine.captel.com for details.
