Table 7-7. Record a Greeting Message [Cont'd]
This tells the modem that the DTE is ready to receive a voice message at the current
compression/sampling settings.
The modem tells the DTE that it can now expect data. The modem enters Voice
Receive Mode. DTMF monitoring is still enabled as well as ADPCM data flow.
User says: "Hello, this is me, press * to skip this message. I'm happy that you have
called, so press 5 to send your fax, or you can leave your message at the beep." User
then hangs up, the message is buffered to the DTE, and the DTE waits for the
message to end. The DTE should have some kind of maximum timer running to ensure
that the user won't speak longer than some predetermined limit. Alternatively, the DTE
can require the user to enter a DTMF tone to terminate transmission of the message to
the DTE.
The modem has noticed (#VSP time out) that the user has finished. The modem
reports this while staying in Voice Receive Mode. DTMF detection and reporting is still
active. The DTE now has the entire greeting message on disk.
The user has inadvertently pressed the "*" button, but the DTE is not interested in this
presently.
The DTE issues a key abort to switch to Online Voice Command Mode.
The modem exits Voice Receive Mode and switches to Online Voice Command Mode.
The DTE did not really have to do this, but wants to make sure that it gets no more
DTMF codes from the handset. Selection of the telephone line here forces the modem
out of Online Voice Command Mode, which is equivalent to hanging up.
