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.
