The NFXGamma.dll in this zip file allows the DTMF answer 
tone to be disabled on all GammaLink fax cards which support
the DTMF answer tone.

Symptoms:  With the Brooktrout fax cards there is a radio 
button on the device profile to disable the DTMF answer tone.
How is this accomplished with a GammaLink fax card?

Note: This patch will only work on Fax for Domino R4.1.
If using Fax for Domino R4.0, please upgrade and then apply 
the patch.
