Activating Tone Dialing (DTMF Suffix Dialing)

You can transmit dual-tone multifrequency (DTMF ) signals to control devices such as an answering machine or automatic information system. 

Step by Step
	You have set up a connection.
	Enter the code.
	You can use the keys "0" through "9", "*", and "#" to transmit DTMF signals.    Ending the call also deactivates DTMF suffix-dialing. Your system may be configured so that you can start DTMF suffix-dialing immediately after setting up a connection.
