A system and a method are disclosed for facilitating sending of DTMF (dual-tone multi-frequency) signals to a destination after connecting to a system by placing a phone call. An entry associated with an application running on a mobile computing device is automatically scanned to detect a telephone number and any string of characters associated with the telephone number. The mobile computing device presents one or more candidate strings of characters that are associated with the telephone number. A user may select the strings of characters to send the DTMF signals after connecting to a destination telephone system. By automatically extracting and displaying the string of characters associated with the telephone number, the user's manual operation associated with accomplishing a task on a remote telephone system is minimized.
