A method and apparatus for facilitating a telephonic connection between a TT type device used by the hearing impaired and other receptive devices (34), such as a telephone, another TT device, a computer database, or like devices. The facilitation is accomplished by employing call trunks and a host computer (10) configured to compatibilize the differently encoded communications. A caller (22) may call the host computer (10) on a toll-free 800 line and charge the access to a prepaid electronic account. The computer prompts the caller for an account number, PIN number, a desired destination phone number, and other information. If sufficient funds are available, the computer connects the caller (22) to the desired destination (34) and charges the caller's account. The host computer (10) is also capable of compatibilizing a caller's TT device to another TT device by running handshake routines and establishing communication protocols. |
