No, Zoom USB TAPI modems WILL NOT work with WIN-911. The Zoom modems will be able to understand DTMF dial tones, but they do not have any sound; even after switching the Sound Source from Runtime Voice Synthesis to Text to Speech WAV files in WIN-911 V7 Configurator. 



They are also not compatible with: 

Windows OS newer than Windows 7 

The newer version of WIN-911 due to the chipset changes 


If you still want to use the Zoom modem, there are new drivers available that may get the modem to work properly but this is very 50/50 at best, depending on the model of the modem.
