10.16 Sending DTMF signals  
During a conversation you sometimes have to send DTMF signals, such as with a voice server, an 
automated attendant or a remotely consulted answering machine. 
By default during a communication, your telephone in SIP mode is configured to send codes in voice 
frequency: enter these codes directly using the keys on your telephone. 
For more information regarding this configuration, contact the person in charge of your installation.
