Hi DanR,

The basic function of a modem is to perform the analog/digital
(modulation/demodulation) exchange of data, not to support voice modulation.
That is an added feature of some categories of modems. The drivers supplied
by Vista or any other version of Windows simply allows for this, not for the
added capability. The only way it's going to work is when the modem
manufacturers write and release the necessary supporting drivers and
software.

Rick... two items in your post.
"for the most part they do not write any of their own other than for their
own hardware, or to provide basic functionality for an industry standard
device"
and...
"and the consumer is left with the option of going without a particular
function, or with purchasing new hardware"
Seems to me an industry standard device is now broken and new hardware
that works with this class of software can not be found. I've been looking
for nearly a year for a voice modem that will work with Vista.

Hi,

You're looking in the wrong place for a driver fix. Microsoft provides
drivers that are supplied to them by the device manufacturers, for the
most part they do not write any of their own other than for their own
hardware, or to provide basic functionality for an industry standard
device. They do not and have not written full driver and software sets to
support added device functionality. It's up to the device manufacturer to
fix, add to, or rewrite drivers, then supply it to Microsoft for
distribution on Windows Update. Many do not do this, some do and just
distribute them on their own. Others do not update drivers for older
devices at all, and the consumer is left with the option of going without
a particular function, or with purchasing new hardware.

Problem: My Rosewill RC-403 PCI Voice/Data/Fax modem isn't working fully
with
a number of TAPI based answering machine programs (e.g. IVM Answering
Attendant, Impulse Technology's CallStation). These programs can pick
up and
record calls but they cannot play a greeting message over the phone
line.
All a caller hears is silence while the greeting is playing. Craig
Duncan at
Impulse Technology has indicated to me in a personal communication (as
well
as on his web site http://www.imptec.com/modems.htm - see Windows Vista
section) that the problem is caused by a "bug" in Vista's Unimodem
Transform
Module that affects all Conexant based voice modems. Since most modems
on
the market today are based on the Conexant chip set, and since most
answering
machine software on the market is TAPI based, the implication is that
many
people are affected by this. In other words, it's very likely that if
someone wants to use their Vista machine to work as an answering
machine,
they'll run into this.

Questions: Is Craig Duncan right about the Unimodem driver and if so,
does
Microsoft intend to fix this soon? If not, can someone recommend a
Voice/Data/Fax modem that will support full TAPI answering machine
functionality running on Vista?
