Abstract
A data storage area allows a user of a wireless communication device to enter data to be processed and transmitted as a series of dual-tone multi-frequency (DTMF) tones. A wireless communication device transmits call origination over the traffic channel and can transmit DTMF tones over the traffic channel. The user may enter data into a storage area along with an indication that the entered data should be processed as DTMF tones. Data entered as DTMF tones is processed and transmitted over the traffic channel as a series of DTMF tones. A data storage area may have predetermined locations wherein data stored in the predetermined locations are processed as DTMF tones. Alternatively, a data flag or other indicator may be associated with the data to indicate processing as DTMF tones.
