ABSTRACT:
A user device and a control system operate to register a user with a communication system. The user device receives a user input requesting registration and transfers call tones to a telephone to initiate a telephone call. The control system answers the telephone call and transfers answer tones. The user device receives the answer tones and transfers user identification tones. The control system receives the user identification tones and a telephone number for the telephone. The control system processes the user identification tones and the telephone number to transfer acceptance tones over the telephone call and to transfer a route instruction to direct communications for the user to a communication device associated with the telephone number. The user device receives the acceptance tones and indicates successful registration to the user.
