SYMPTOMS
When you are using the Microsoft Phone software on a Compaq Presario computer, you cannot send DTMF tones while using Speaker Phone.



CAUSE
DTMF tones are disabled while using Speaker Phone because of problems with the Presario's preinstalled modem. Sending a DTMF tone while using Speaker Phone would turn off Speaker Phone, hanging up the call.



MORE INFORMATION
DTMF, or touch-tone, is a method used by the telephone system to communicate the keys pressed when you dial. Pressing a key generates two simultaneous tones, one for the row and one for the column. These are decoded by the exchange to determine which key was pressed.
