What are the minimum technical requirements for CapTel service?

Asked 2 months ago
To use CapTel service effectively, users must ensure that they meet certain minimum technical requirements. CapTel phones, which are designed to provide captioning of telephone conversations, generally require a reliable high-speed internet connection or a traditional telephone line, depending on the specific CapTel device used. If a user is utilizing a CapTel phone that operates over the internet, connecting the device to a broadband service such as DSL, cable, or fiber optic is essential. Additionally, users should verify that their equipment is compatible with the CapTel service. It is also important for users to have a standard telephone service or an active broadband internet connection, as either option is necessary for the captions to be received alongside the voice audio. Furthermore, ensuring that any necessary updates or software associated with the CapTel device are installed can enhance performance and reliability. For more detailed information on specific models and connection types, users are encouraged to check the relevant sections on the CapTel website.
