Zoom Voice Modem - no audio

    I have a Zoom 3025C Voice Modem and some telephone answering software. When a
    call comes in, the modem answers the line but when the message is playing to
    the caller, there is no audio (i.e. the caller hears no message). I have
    tried a couple of answering machine programs but they all have the same
    problem. Called ID works fine but just no sound for the outgoing message over
    the modem.
    Anyone else seen this problem in Vista? It all worked fine in XP and I also
    tried setting the program for XP compatability mode but still have the audio
    problem.

    Same exact problem with Conexant D850 56K v.92 DFVc Modem.
    No outgoing greeting but can record incoming message.

    Stuart... I ran across a Vista driver for your Zoom modem.

    http://voicent.com/kb/index.php/sup...updated-zoom-modem-driver-for-microsoft-vista

    Please post back and let me know if this fixes your outgoing greeting
    (silence) problem. If it does I will search the world for this modem.

    sorry forgot to reply. The new drivers did not fix the problem. I see the
    same problem with several different telephone answering programs.

    Thanks anyway.

    Vista handles audio differently than XP or its predecessors. Unless
    Zoom comes up with a fix, don't expect the audio features of the modem
    to work as they did in those systems.

    Actually, I developed my own telephone answering application for XP and when
    I recompiled for Vista the audio problem showed up. Do you have any pointers
    about what changed in Vista for TAPI so I can fix my application? Or would it
    still be a driver problem that Zoom or Conexant has to fix?

    Stuart, if you ever learn anything about this problem please post back. I
    have exactly the same symptoms as you do with my answering machine software.

    One Win32 telephony product that does work with the Zoom 3025C and
    Voicent's Vista driver is Communicate!. At least it works for me. Other
    products have the same problem indicated by others - no outgoing
    message.

    Thanks for the tip. I'm still looking for a solution.
    When you installed this software in Vista did the answering machine
    functions work immediately? Did you have to patch? Did it require the Zoom
    Vista driver before functions worked? Did you at first have the no outgoing
    greeting problem?

    Have you gone into Control Panel>Sounds and checked to see if the voice modem is
    listed there? (Make sure to right click the windows and select Show Disabled
    Devices and Show Disconnected Devices.)

    No the modem is not listed. Only thing there is "Speakers / Headphones". In
    Vista device manager under "Sound, video and game controllers" I do have
    "Unimodem Half-Duplex Audio Device" listed. It's properties indicate the
    device is working properly.

    I dual boot and under "XP / Sounds and Audio Devices Properties / Hardware"
    I have "Unimodem Half-Duplex Audio Driver" listed. Under its properties
    "Modem Wave Driver" is listed. The modem works fine in XP.

    I can't find a reference to "Modem Wave Driver" anywhere in Vista. I thought
    that in the past I had found that somewhere but can't find it now.

    However (in Vista) my answering machine software is able to record incoming
    messages but will not send audio (greeting) out through the modem. I have
    researched this extensively in Feb / March but sort of gave up and just boot
    to XP to use this software. I would like to find a solution. I would buy a
    new modem if I knew of a model that would work with Vista.

    Do you have XP installation disks?
    Tried running the software in XP compatibility mode?
    Any Vista drivers from Zoom's site?
    Anything from Window's Update?
    Tried uninstalling the Audio Driver in Device Manager, rebooting and letting
    Vista reinstall the driver?

    Modem is Conexant D850 56K V.92 DFVc Modem
    Vista prefers to install a generic modem driver that has no voice
    capabilites.
    I have not tried removing the "Unimodem Half-Duplex Audio Device" from
    device manager. But it was installed with the Conexant driver. I tried at
    least 5 different Conexant drivers and only one of them gave me any voice
    capabilites at all with Vista.
    I've heard that certain Zoom modems work with this type of software. (with
    updated Vista driver) I've been leary of ordering one for fear it still
    wouldn't work and then I'm out more $$. Vista has already cost me much more
    than the $160 for the DVD.
    I'll have to do more research as maybe there are new drivers out there since
    the last 6 weeks.

    Thanks for helping out.

    Hi Stuart,

    It could be the builtin DRM features in Vista that may consider the
    modem an unsafe audio output and thereby refuses to play audio through
    it.

    Even a driver update from Zoom would not solve this problem.

    I am having more or less the exact same problem with Windows Vista 64
    bit (but with a different modem).

    This is a known problem with all voice modems that use the Conexant chipset.
    And most do. There is no fix.
