Quoting: 8.1.3. Voice Transmit Mode Voice Transmit Mode is entered when the DTE issues the #VTX command because it 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) VOICE 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 a 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 Command 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.
