Heh, I was right ;)
Check this:


8.1.3. Voice Transmit Mode
Voice Transmit Mode is entered when the DTE issues the #VTX command because
wants to transmit voice data. This mode is typically used when playing back
greeting messages or previously received/recorded messages.

8.2.1. Call establishment - Originate
Directed Originate (Dial as a specific modem type)
The modem dials and reports call progress to the DTE, which reduces to
reporting NO DIALTONE, or BUSY.

8.2.7. Voice Playback
To effect playback of a message recorded via a handset or microphone, or of
message recorded during a voice call, the DTE must configure the modem for
Voice Mode (#CLS=8) and select the proper relay setup (#VLS) to instruct the
modem whether to use the handset or speaker. When a device other that the
telephone line is selected, the modem immediately enters Online Voice
Mode (indicated by VCON). When the DTE decides to play the message, it
issues the #VTX command, and the modem immediately switches to Voice
Transmit Mode. Since the speaker or handset is already switched in, the
modem immediately issues the CONNECT message indicating that the modem is in
Voice Transmit Mode and is expecting Voice data from the DTE.

So... You have to use any kind of rockwell based modem. Or get the
documentation for your modem.
