A voice modem is device capable of playing and recording audio over a telephone line. Modems are originally made for data or fax communications. These modems cannot be used with Voicent software. A voice modem is usually marked as Data/Fax/Voice modem.
Please note that supporting V.90 or V.92 data transmission standards does not imply your modem is voice capable. A good indication of voice capability is the inclusion of voice mail software in the modem package.
If you receive an error message “Fail to detect a voice capable modem” during installation or during Voicent Gateway startup, your computer does not have a voice modem. Without a voice modem, Voicent software cannot continue.
