Detecting Ring events when the modem is in Voice mode (fclass=8)

Dec 23, 2010 at 8:22 PM

Hello there,

I'm running into a problem detecting Ring events when then modem is in Voice mode (fclass=8).

Is it possible to do this?

I'm using a Multitech MultiModem MT5656ZDX-V in conjunction with the Microsoft Windows driver.

In the driver modem properties i pass in the following initialization parameter:

at+fclass=8;+vgt=200;+vtd=25;

fclass=8 - sets the device to voice mode, so I can increase the volume

vgt=200 - increases the volume

vtd=25 shorten Beep Tone Duration Timer, I'm doing this because i think it helps avoid problem detecting button press events ...

Is there a better way of doing this?

When I remove the above parameters from device manager ~Advanced tab, the ring event works. However, I use these parameters to increase the volume and shorten the tone duration.

Can someone with more experience with this stuff help me out???

Thanks,

Tony
