Description

              Text over IP (or ToIP) is a means of providing a real-time text service that operates over IP-based networks. It complements Voice over IP (VoIP) and Video over IP.

Real-time text is streaming text that is transmitted as it is produced, allowing text to be used conversationally. Real-time text is designed for conversational use where people interactively converse with each other.

Real-time Text over IP can be used:

v      By people with hearing loss or speech impairments to communicate with non-disabled and deaf or hard of hearing or speech impaired people.

v      To provide real time captioning of a voice conversation for people with a hearing loss. See also captioned telephony in Telecommunications Relay Service
